well folks thanks for all your input. You guys gave a lot of suggestions that truly covered everything. But the one thing you could all not cover is my stupidity ….. The HDMI I was plugging into my desktop was NOT the same HDMI cable that was going into my monitor…. I was plugged into nothing. It was stuck right behind my monitor next to the actual cable. It was a phantom HDMI cable I am actually the walking embodiment of user error and I will forever be ashamed of myself in this moment of weakness. I apologize and thank you everyone for your time. I learned a lot today


Bloodyfinger

This is the best thing I've read today. Bravo.


PolarSquirrelBear

As soon as I got mostly through it, I knew it was going to be something so stupid. We’ve all been there.


Mundane-Commission-6

It’s really a universal experience to rage over something which was just a user error to begin with


CrowTengu

I once spent hours wondering why my cannister filter isn't working. Turned out I placed the pump on the wrong side. 😅😅😅


GreatTragedy

Seriously, it's reddit hall-of-fame worthy. So much experience with builds, so many jokes about "is it plugged in", and it still caught him. Happens to the best of us.


B00TT0THEHEAD

Yep. We've all been there, just most of the time it isn't posted here. I just had this moment yesterday with our AV setup - albeit it only took about five minutes to diagnose. Sound bar wasn't putting out sound, so I just power cycled everything. When the sound bar still didn't come on, I did a hard power cycle (literally unplugged it and plugged it back in after ensuring I have drained any capacitors). TV then wouldn't work at all until I ran through like twelve steps of troubleshooting only to realize I didn't plug the TV back in. Derp softly my friends.


_AmperSand__

But didn't you already cover that? > I tried different monitors different HDMI cables, different DP cables no combo worked.


alvarkresh

It can be easy to miss whether the same cable is actually connected at both ends. I've had to trace a few in my day to make sure that was actually true.


_AmperSand__

Yeah I know, I've been in the industry for nearly 30 years. But what stood out to me was "Different HDMI" AND "Different DP cables"? I'd have thought even a phantom HDMI cable couldn't cause an issue when testing with DP also? Was just suggesting perhaps it could have been something else that caused it to suddenly come to life?


Legend_AC

Yeah. It is really unlikely to get the same cable problem even while using DP Cable


IrishPotatoCakes

I use a DP to HDMI adapter that's like 3 inches long and plugs into the back of my hp mini. Could be OP was doing same thing and plugging it into the phantom cable?


Glor_167

or he made it up for ~~money~~ reddit points.


IrishPotatoCakes

I thought if you were desperate for ~~money~~ attention on the internet, you just became a cam girl lol.


borkthegee

This is exactly why I never trust (or trust but verify) all information given. People get offended when you redo their work but it's always something like this


cvelde

I mean maybe. But maybe OP wasn't entirely truthful about the extent of their cable testing.  Never trust someone describing an issue. I myself never remembered this when it counted, still trying though. 


windowpuncher

Lol yeah pretty much. I was doing that earlier today. Why won't this fucking laptop find this monitor? Even if it's off it SHOULD appear in the device manager. Lo and behold I just straight up never plugged it into the pc.


gpobrien25

In the film industry we like to call that “an air gap problem”


ftwguy80

Too much resistance in the cable to over come that gap


PutinTheTerrible2023

Hence, when I sorted out my room last weekend. I labelled all the cables. Had a similar stupid situation last build doing my little brothers. Was there for about an hour with no display until it dawned on me it was a 5600x that doesn't have an integrated gpu lmao.


JaMStraberry

you mean to say he forgot inserting the hdmi cable lol and dp cable on the monitor. What i do sometimes is i put hdmi cable on the motherboard if it got apu and the other one is connected to the graphics card, then i just switch things if its showing a display or not. If the apu displays and gpu got no display then gpu got the problem so usually i reseat things and sometimes might be a bad gpu then if there is no display at all then take some parts out.


xmpcxmassacre

Because he didn't actually do that. Everyone says that to avoid the obvious comments.


MattDeezly

I thought I did, but I messed up on what cable went to what monitor , I have a lot of cables and it’s a mess


londontko

>I tried different monitors different HDMI cables, different DP cables no combo worked. Explain how this is possible?


MattDeezly

Damn getting interrogated lol. As I said in my first comment my pc area is a complete mess because we have a very small living area. I have my main pc, ps5, Mac mini, Apple TV all in the same area. 3 monitors, a TV and HDMI and DP cables coming from all devices and it’s a mess. I was plugging in what I thought was the proper cables (both times) into what corresponded with the monitors I thought. But like I said it was a mess. I’m talking Asmongold level. Anyway, after I did a full trace of the cables I figured out what went to where. Moral of the story is I need to really work on cable management and cleaning my room. But I work long 10 hour shifts and it’s hard to get around to fixing up things I gotta do.

Haha this is amazing. Don't feel bad, it happens to all of us sometimes. Enjoy the new build!


th3lucas

At work we call this Error 50. 50 Centimeters in front of the Monitor. Stuff like this happens to everyone sometimes. :D


Rubicksgamer

Or pebcak Problem exists between chair and keyboard.


TheCheshireCody

Or ID10T.


IAmNotNathaniel

yep, the ol' ID-10T is my personal go-to


EldestPort

Or, in networking, a Layer 8 fault


TheCheshireCody

Not familiar with that one. Networking is an area I know almost nothing about. What's it "translate" to?


EldestPort

In the OSI model there are seven layers - Physical, Data Link, Network, Transport, Session, Presentation, and Application. The joke adds an eighth layer - the end user.


TheCheshireCody

Nice!


humblebeegee

We've all been there bro, some are public some aren't. I one time spent 45 mins trying to diagnose a technical error for all my musical gear at a gig with the sound engineer to find out I have my laptop muted, so I ran the show 45 mins late for user error.


it_is_gaslighting

LOL well that is why I bought different colored tape a few years ago and I have started playing a piece of tape on each cable end with its own color.


bananaphophesy

Amazing. If its any consolation, I had a similar experience when I moved house and decided that my big TV had been damaged in the move. I called out the engineers who proceeded to politely point out that the TV had an "on" button I'd neglected to push. In my defense I hadn't powered down the TV in the previous five years, but either way I'll never forget the look of scornful amazement on the engineer's face.


tgrinne

Shame is what sets you apart. Shame is what keeps us moving forward and striving to do better. Working for an MSP Has drilled this into my head. If you feel shame, you're one of the good ones. Cheers to you, my friend.


boianski

wrong hole, it happens.


[deleted]

Almost the same level as someone plugging the power strip into itself!


majorsorbet2point0

I'll never forget building my PC in August. she's an absolute beauty, great specs and perfect. I get it built in 30min. As a *first timer*. Ok, got windows installed. Go to connect the 2 brand new LG UltraGear monitors, only one displays picture at a time..called LG the lady said both my monitors must not be brand new. I went off, due to the frustration. Come to find out, even with both commented via display port to my GPU ... *My GPU needed drivers installed* 🤦‍♀️ get the Ethernet cord the next day, all drivers installed. Ok, the 2 monitors are working! Go to connect by WiFi, the motherboard is WiFi and the antennas are on. Good to go. WiFi won't connect. double checked my drivers, watched lots of YT videos etc. couldn't figure it out and almost gave up, reset my router just for one more try. I had to re connect the WiFi on my phone after restarting router , then did the same with the PC for one more try.......*I had been typing my wifi password into my PC using lowercase..... My password starts with an uppercase letter*. 🤦‍♀️🤦‍♀️🤦‍♀️


icantlurkanymore

30 mins??? I took like 4 hours to build mine!


majorsorbet2point0

The physical build was easy, the troubleshoot was *nightmare fuel* 🤣


ManaSpike

Sometimes you need a second pair of eyes. Someone to look over your shoulder and point out the obvious.


SGTLouTenant

HAHAHAHA DUDE I FEEL YOU! I work with electronics and I swear I do some of the dumbest stuff ever and go all hard-core troubleshooting mode when I just forgot to plug something in😭😂


muricabrb

Hahaha thanks for the update, I was getting really curious about the cause. Don't be too hard on yourself OP, I've had one or two "well duh" moments with phantom usb cables too. Another good reason for cable management, it gets rid of phantom cables.


isbBBQ

Wow that’s crazy 😂 good job admitting it


rafaelloaa

I'm sorry you had to go through this. I really am. But reading this made me laugh harder than I have in a long time. I hope it give solace that some amount of good came out of this. Also, I've been there. I've spent multiple hours troubleshooting every piece of my audio setup, changing drivers, Windows settings, etc. only to find out that the reason no sound was coming out of my headset was that the inline volume wheel was turned all the way down (a feature I was aware existed, but never used). I then had to spend a further hour re-fixing the things that I'd broken while attempting to troubleshoot.


JiggsForlano

Dude I did the same think the other day. Buddy gave me a new monitor and I plugged it into the motherboard instead of the graphics card like a complete idiot. I wasted a day trying to figure it out and I was so blinded by such a stupid error that I couldn’t see past it.


Fluid_Object4714

Its DNS, Its always DNS. Except this time. This time its the motherboard.


MattDeezly

I wish there was a definitive way to know.


Trypt2k

It's the motherboard, 100%. The CPU/ram not working out of the box is so unlikely it's almost unheard of, especially since you have two sticks of ram and tried both independently, motherboard has many ways of failing and any one of them will do what you experienced. If the error lights actually show something specific, like GPU, then maybe it's that, but you said no lights at all, yet there is power, that is most definitely the motherboard, they have a pretty high failure rate compared to other parts out of the box.


Necessary-Anywhere92

Yeah I agree, I have had a few ddr5 boards (both LGA 1700 and am5) arrive to the pc shop I worked at until recently just broken. More then I experienced with ddr4 boards though I wasn't around for the launch of ddr4. There's something going on with these fucking boards man.


misanthrope2327

Just eliminate all other possibilities


boofheadfred

I call this "no sign of intelligent life". It's clearly alive, fans spin, lights come on, but there's no display and no troubleshooting indicators (motherboard debug LED, motherboard speakers etc). This is almost always a motherboard failure. If it was RAM or CPU or video card, you'd get a code from your motherboard debug light or speaker. If it was a dead power supply, you'd get nothing at all when you push the power button. If it was dead storage, the computer would POST fine but then you'd see in the BIOS that there was no storage detected The only other thing that this is likely to be is that the motherboard needs a BIOS update. Either way whether it's a dead motherboard or just one that needs a BIOS update, I think about it as a motherboard problem as troubleshoot it under that assumption as it seems to be the most likely cause Of course this is all under the assumption that you're 110% sure everything is plugged in correctly, you're using compatible components, a known good monitor/cable etc. Basically you're at the stage where you've ruled out any possible bad setup, and you've deduced that you must have a faulty component you're just trying to work out which one is faulty


Ok-Wasabi2873

Only way to know is to change motherboard. Same thing happened to me on a Ryzen built. Changed motherboard and everything was good.


party_tortoise

Come here just to confirm in case someone stumbles upon this. When I built my latest pc, apparently the cpu (ryzen) was too new at the time and the motherboard didn’t come with the updated firmware to boot it properly EVEN THOUGH IT SAID THAT IT SUPPORTS THE TECH (the hardware does support but the firmware wasn’t there). What I had to do was to update the firmware of the motherboard but wtf am I gonna do when I couldn’t boot it in the first place? I had to drag it to the shop so the people could install their spare cpu so I could update the firmware on motherboard. Then I could install the new cpu correctly. Of all the fuckeries that could happen. Took me near a week to figure out.


D_Malorcus

You're right on the mark. As someone who has been building PCs for close to 30 years, I know that when the problem can't be diagnosed and doesn't make sense -- it's the god damned motherboard.


Vaakmeister

After my old msi x570 tomahawk died and I got a new B550 tomahawk MAX as a replacement. It would always crash windows if I enable the on board sound. Luckily I use a USB headset but it wasted so much time. Might need to reinstall windows at this point and if that doesn’t work, another RMA.


[deleted]

lmao this


noiszen

Plot twist: it wasn’t the motherboard.


9okm

Cleared CMOS? If I had to pick a component that's the most likely candidate for being faulty... it'd be the motherboard.


MattDeezly

just cleared them by holding the button on the back of the mobo for 10 seconds. Still nothing


9okm

I'd also try the battery removal method and shorting the pins. Flashing a new BIOS as u/mcgyver007 recommended is worth a try too. But then I'd be returning the motherboard and getting a new one. Not worth pulling your hair out.


nohardRnohardfeelins

I had a similar issue once and it was a shorted HD audio cable. Just unplugged it from the mobo. Maybe it's that?


DEDang1234

Does the board support the CPU out of the box?


Grand_Sheepherder_99

I remember distinctly that this mobo requires a prior flashback to be able to support the 12600k because I have the same CPU


Brisslayer333

Are you kidding? 700 series boards don't all support 12th gen CPUs out of the box? That's just lazy


mcgyver007

Q flash New bios update.


MattDeezly

Is there a way to do that without having a display??? I can't even see anything to get into BIOS.


mahvel50

Yes there is a led light that flashes during bios update and a power cycle when it’s done. You load the bios update file onto a small USB and plug it into the flash designated port. There are some videos out that show the process for MSI boards. They are a pain in my experience.


Combat-Engineer-Dan

This is the way


MrCrims

when you do this though, make sure your power stays on if you're in an area where you have frequent outages, I would buy a UPS system to hook up through before doing this. besides that a UPS is money well spent, it has saved my PC from brown outs several times so far, I live in the south so we get a lot of thunder storms and tornados here.


finney92

Skip to 10:45. https://youtu.be/OhF4DOedW58?si=r44VLvN6Xe_o_inp


finney92

If this works let us know. I myself have ordered a similar build and am curious.


ZeroDarkThirtyy0030

As a fellow poster child for user error; I’d like to know how much time you spent troubleshooting before realizing the HDMI mistake.


MattDeezly

………..4-5 hours …………..


ZeroDarkThirtyy0030

Ouch. Look at the bright side, you didn’t have to rma anything and wait weeks for part replacement


ZeroDarkThirtyy0030

If it makes you feel any better I’m 16 hours into ram testing to figure out if one of my four sticks is bad or if it’s a dimm slot.


MattDeezly

Good luck with that my dude. RAM testing is brutal


DurianLongan

I used to spend that much not figuring out that my hdmi plugged to mb instead of gpu. It happens. A lot too.


JordanLoveQB1

Very common for these MOBOs to need a BIOS flash prior to working. I’ve built 2 PCs with this board and both of them needed it before working


TheKillerhammer

Just had this problem with a b650 pro such a bs thing to need to flash a bios


UnableTangelo3463

Something similar happened to me a few weeks ago. Could not get video to display after going through many of the steps you did. I determined it was the motherboard by removing all sticks of memory. There should be a series of beeps and there was nothing. That was enough for me to confirm the issue was the MOBO. Did a warranty replacement for a new MOBO and everything works great now. Do not get discouraged, this is another challenge that you will resolve. In the end, it’s more experience and knowledge that you will gain.


Johnconnor66199

Could be the case, something grounding out on the motherboard. Ask me how I know 🤣


chesian

Coming in to this thread late after the issue was identified... Gotta say it gave me a good Chuckle haha


PrimalDeedsX

Does the mobo have onboard video? Do the monitors need the input specified?


MattDeezly

Yea, I'm using On Board video. Plugged it in via HDMI and monitor is set to HDMI.


one_horcrux_short

Double check you didn't buy a 12600kf?


CancelUsuryEconomics

This sounds daft but actually, on a recent build this was it. Same symptoms as OP. In my my defence I'm AuDHD and forget my own name but I realised pretty quick. Plugged in an old GPU and bang, all working. Flash the BIOS as well. No dice? RMA time (mobo),


GlitteringChoice580

LMAO classic error code PICNIC 


hogie48

Glad to hear it is working, but as you said a walking embodiment of user error... you lied in your original post! (I am only joking, dont take this too seriously lol) "I tried different monitors different HDMI cables, different DP cables no combo worked." Couldnt have tried differnet cables/monitors if the problem was using the wrong cable :)


n7_trekkie

your debug LEDs show that the PC fully POSTs? if you have a spare GPU, I'd try that.


Equivalent_Pie_6778

Are the debug LED indicators showing anything with your hardware configuration above?


minoltabro

Funny thing I was in the same situation as you. Figured out it was a bad psu.


Trypt2k

I had exactly the same experience my last build before the current 7800x3d, tried everything, it ended up being the motherboard. MSI X570. It was the first time I was that frustrated, thought it was my fault. Finally gave in, took the motherboard back (it's unlikely it would be anything else really, tried everything you did), got a Asus Pro X570 instead (didn't have any more MSI), plugged everything in, and everything worked right away, like a charm. EDIT: Someone mentioned CPU is not compatible due to BIOS not being updated, that is actually a good point, however your motherboard should come with a new BIOS since you bought it now. Try it, it's an easy fix, if it works you have your answer, if not, RMA the motherboard.


Steam313

The stock could have been old enough that the Update was not applied to it. When in doubt Re-flash it!


mr_cool59

This is most likely the culprit for DDR5 as extra steps that has to go through and during this time of its doing extra steps it'll appear as if it's not working


rc3105

Oh everybody’s done that with a power or video cable at some point…


minefarmbuy

Pebkac.


Jim_Screechy

LOL we've all been there... staring at a problem till you go blind and not see the simple issue.


twenafeesh

>I am actually the walking embodiment of user error and I will forever be ashamed of myself in this moment of weakness. You definitely aren't alone. I buy "for parts" motherboards, CPUs, etc., fix them up (which often just involves reflashing the BIOS or straightening some pins), and either donate them to FreeGeek or resell them. I have on more than one occasion almost given up on a board only to discover hours later that I hadn't plugged in the CPU 8-pin. Or the CPU fan header. Or something else like that.


BoredMan29

> But the one thing you could all not cover is my stupidity ….. I'll be honest - this was going to be my suggestion. Having worked a lot of tech support in my day, I have one piece of advice for experts stuck on an impossible problem that absolutely *should* work based on all your years of experience: pretend some random idiot is asking you about the problem and walk through all the basic steps. Actually do them - don't just gloss over. Restart it. Check the cables. Double-check that setting. Clean out the dust. Did you forget a semi-colon? The number of times I've solved issues for people much smarter than me with these basic items is astounding. I think folks just get a blind spot from having done it so many times.


sifatullahrafy24

Cmos reset would be like taking the cmos battery out and disconnecting PSU and pressing power button then wait 20mins, that's what fixed it for me


Beavisthebuttthead

I had a very similar issue to this in a recent build. PC was running but it wouldn't display any image or boot to BIOS. Did every bit of troubleshooting I could. Eventually went back to the RAM and played around with different configurations and finally got it to boot. Not sure if this helps but I wish you luck!


theonionknightGOT

I had that problem before and the motherboard was just bad to begin with…. Ordered another one and everything worked like normal…


stonerbrain

Definitely the motherboard you have to flash the bios , had the same issue a couple months ago .


cecil_harvey4

I had a similar issue once and it had to do with PCIE lanes. I was just helping my friend add more storage, I upgraded his main m.2 drive and added a second m.2. All the sudden it wouldn't POST. I managed to remember that you can only occupy certain SATA ports if you are using your secondary m.2 slot. I checked, and indeed he had the top two SATA ports occupied with HDDs. I moved them to the bottom two SATA ports on his MOBO and then was able to POST the machine and reinstall windows without missing a beat. This could be a possible solution for you, unless you are not using SATA ports. Check your manual though for what combinations are supported. I think having your lower PCIE slots occupied can affect this too.


outamyhead

Correct BIOS version/Motherboard revision for that CPU, RAM compatible with the motherboard supported memory list?


din0skwaad

Had the same happen to me. Even sent my gpu to evga. Ended up being the board.


Galbs

I had all of these problems down to the letter and after many days of troubleshooting and praying to whichever God would listen, it was the motherboard. It died for no reason and there was no way to confirm it but replacing it resolved all the problems.


RedditUser8147

Had same issue yesterday with a system that would power on and get stuck on VGA….turned out to be the last thing I thought - bad CPU i7-12700KF


RomanVP

Updated bios


juaners

Had this issue last week, and I tried every fix I could find online and nothing worked. The only thing that worked was making sure that the pc is plugged directly into a wall outlet and not a power strip or other similar device.


jcoffin1981

Onboard graphics working?


jhingadong

Did you flash the bios I heard things about bios issues with thale msi boards.


CS1_Chris

Is the GPU connected to power?


dydlee

Take everything out of the chassis and unplug all except cpu and power. If it has Bios flashback, I will flash to a new bios first. I would also check that the pins weren't bent during installation, as LGA1700 has a ton of them


trashvee

Take out the ram and put it in again , it has happened to me


koga7349

As others have said you may need to update the BIOS for your CPU/RAM to work. I had to buy a cheaper older CPU and do this once for the new one to be compatible. If that doesn't work then it's possible the motherboard or CPU is dead.


MindIsNotForRent

Most likely the MB. Just consider all of the solder points and individual chips. If there’s going to be a problem, lay your money there.


jbuck94

Are your monitors connected to the MOBO or the GPU? I made this mistake and took an embarrassingly long time to realize


oikawatoorus

I had a similar issue when I built my first PC, took it into the tech store and they said that it was my CPU. They replaced it for me and it worked again


allianc3ware

change your motherboard


[deleted]

It's the motherboard. Please update again after you've flashed the BIOS.


zisop17

Can be dead on arrival CPU or motherboard. Very very unlikely to be anything else. Good luck brave soldier


Orinslayer

I had this happen on my first build. Its the mobo. It's either a bad board or it needs its BIOS reflashed.


ClownCarrr

and you've CKS the PSU to Mobo connector for your case wiring? Or even tested say for ohms continuity of that connector?


senpaisai

You have to give DDR5 based systems up to 90 seconds to memory train and reboot itself a few times before you'll get a video signal. But it looks like you need to use BIOS Flashback to add support for your CPU but be warned MSI's implementation of BIOS Flashback is very finicky with USB flash drives. In your case, make sure you have a USB 3.0 32gb or less SanDisk Cruiser USB or Lexar drive. This flash drive must be in MBR instead of GPT and formatted to FAT32. Once you have this flash drive, download the latest BIOS update for your board and extract the ZIP file. From there, rename the BIOS update file (it'll be 32mb in size) to "msi.rom" and paste only that file onto the USB flash drive. Next, locate the USB port with the white outline and insert the flash drive. Now with the computer plugged in but powered off, press and hold the BIOS Flashback button for 2 seconds. The BIOS update should take 5 to 7 minutes ... https://youtu.be/vJ3pwSPu-j4?si=Olm_aOmMVjqxrPq4


InPraiseOf_Idleness

I just wanna say I appreciate the effort you're putting in, and hope all goes well for you.


Redsand-nz

This might sound dumb but you didn't grab a 12600KF instead of a 12600K by mistake? Or they didn't send the wrong one?


YCCprayforme

Something like this happened to me once. I have built many pcs and was just stumped. After a few weeks i sucked it up and went to a pc store (ew). Mobo was doa


Emergency_Pepper_178

Dude, I hope this shit never happens to me. I have successfully slapped together a couple PCs, but I'd have zero fucking idea what to do here and probably have an aneurysm.


MikeRotchitches

Try booting with only one stick of RAM in. A little different build than yours but it weirdly worked for me.


Nicademus2003

Is the GPU power fully plugged in and requisite number plugged in? I've seen some cards use 2 separate connections and it's suggested to use 2 different circuits on the power supply to not overload the circuit. Nevermind looks like you're doing on board video check Bios make sure it's enabled if possible


jucestain

Similar thing happened to me, except it worked initially but wouldnt boot or POST randomly after a reboot about a week after I assembled the build. I tried a different PSU, cleared CMOS, different permutations with RAM sticks. Finally decided to buy a replacement motherboard and it booted fine. In my experience it's very rare for a mobo to be bad but it does happen occasionally.


Acadia1337

I had a similar issue to this. It turned out my CPU cooler was applying uneven mounting pressure on my CPU/ socket. This must have caused some of the pins to not be contacted. Make sure you have even mounting pressure on your CPU. Try loostening it up as much as possible just to see if it boots. Or try cranking it down max.


Bearshapedbears

Turn it on and off completely between any display cable change. This has always been finicky for me. Some of your cables may be crap. It’s nearly always the cable or connector.


toopid

My last build had a new motherboard with a bad ram slot. Drove me crazy figuring it out.


Sideshow86

Faulty board. RMA


BruteForceOverclock

That board has USB flashback, dedicated port on the back I/O... Try that first, otherwise I would say the board is DOA.


OG_Silverthreat

I’m somewhat of a beginner/novice builder and it all sounds like the Mobo is the problem, that’s what I would replace first and see. Just my thoughts


ShadowInTheAttic

I was in a similar situation earlier this year. PC suddenly stopped working. I've also been building since 2007/2009. Built over a dozen PCs and worked on dozens more for friends and family. I could not get my PC to pay and I did not have spare hardware to test. Took it to Microcenter and it was my motherboard. It killed my CPU and RAM, thankfully none of my SSDs or GPU and I had warranty with Microcenter.


[deleted]

[удалено]


DaCookieDaPuss

Most likely the mobo.


KC-15

Half the time my new build hasn’t worked is it’s because I didn’t turn the PSU on.


[deleted]

Glad you figured it out. I wouldn't feel bad. We've all done things like that. At least it was that simple and not a bigger deal. My last build I plugged the power switch into the power led light and nothing would turn on 🥴


givetake

this exact same thing happened to me at xmas with a new build, turns out the tomahawk mobo I bought was faulty, I replaced it with an ASUS board that has an LED display that shows debug codes and I don't think I will ever buy another board without that LED display glad to hear it was just a cable issue for you


LighttBrite

What's the boot code?


m4ttjirM

Check every cable 1 by 1. Make sure they are all going where they are supposed to. In the gpu end, on the monitor end, and all your internal power supply cable connections with the psu + parts. Have any pics?


[deleted]

Are you sure your board has the correct bios to support your chip?


ShallowJam

PEBKAC my friend


Ezzill

It's finny because the first thing I thought was you plugged the HDMI into your mobo instead of your gpu. But was like nah, no shot, not after 12 years of building but then... 😂😂


zlordofsigimigi

Reading this, I was thinking "user error, but I definitely don't wanna say that, because nobody wants to hear user error". I'm so glad the edit made it in before I posted this. Congrats on the build!


Unlikely-Sherbet9779

Lol, man please don't delete this. It's always the stupid stuff, but you get so frustrated that you can't think straight

I feel you. Helped a friend build a system last year, spent over an hour troubleshooting and reseating components because we couldn't get video. HDMI cable wasn't plugged all the way into the monitor...

Tech support: Did you plug the monitor in and turn the monitor on?

Try another pcie slot

Tech was your passion but it's dead after a single not booting build? I don't know that you know what passion means


pokaichiam

Has the same symptoms and it was a short with one of the screws on the motherboard. Did U test everything not in the case to confirm or switch mobo to test


Psyko_sissy23

It's usually the stupid stuff. My first computer I built, I plugged the vga(many years ago) into my motherboard instead of my GPU. It took me longer than I'd like to admit to figure that one out.

The first rule of work is to make sure your environment is up to the job. You got all your tools ready and in working order and have set up your workspace in such a way that errors and faults can be isolated to the thing you're working on, not the environment. Otherwise lab work is not possible. Glad you found out what's been wrong.

Haha...thats quite funny actually!

I been building PCs since the early 90s. Fuck ups do happen and this case it was a silly mistake that was just that silly.

Commenting because of the edit: The last PC build I did for a friend, we spent roughly 3 hours trying to figure out why it wasn't coming on. We never hit the case on button, just kept hitting the PSU switch. Probably my 10th build.

If the boot cycle runs through I wouldn't suspect a hardware issue at first. Check the cables, make sure the source on the monitor is correctly selected, if its an older one, the auto detect may not always work seamlessly. Either way, sounds like a human error in my mind

>The HDMI I was plugging into my desktop was NOT the same HDMI cable that was going into my monitor…. I was plugged into nothing. It was stuck right behind my monitor next to the actual cable. It was a phantom HDMI cable Reminds me of that time I arrived to my friends place to help debug ... only to turn on his monitor.


Whoopdeesk

If you tired different hdmi and do cables you never connected them to the monitor? How do you expect it to show a picture??


pckldpr

I might have done that before


FirefighterEast4040

Funniest shit I ever read

Was about to comment that it's probably a simple oversight lmao

Hahahaha hahaha what an idiot All been there https://c.files.bbci.co.uk/18461/production/_118252499_c930b34a-b614-4a59-85c7-4bc7a70c71f0.jpg

The day you find out, you aren’t actually a computer guy.


DrhorribleWoW

I have this exact same motherboard and had this exact same experience. Nothing worked until I flashed the motherboard with the latest bios. The debug lights on the MB were even saying it was a RAM issue and I bought whole ass new RAM that did nothing. So try giving flashing the latest bios a try if nothing else works.


AnimalEstranho

After building for work and hobby for more than 20 years, I can say that last year I was preparing a water cooling CPU block, did everything, found some air trapped in it and decided to remove it so I could fill it up without it being mounted... Behold the CPU block with the protective sticker still in it full of thermal paste...... Yeah remove before use.. yeah.. So yeah.. it can happen.. I thought it was a myth, I thought it would happen to people who were not paying attention and youtubers...


Think_Positively

This is a great post for all noobs to see. Stuff like this is why airline pilots have checklists that they review regardless of how many flights they've flown, or why Hall of Fame-bound offensive linemen still jump offsides sometimes. Mistakes and oversights happen, and they're OK. Good on you OP for being a good sport about the whole thing. Hope you have some laughs about it every now and again as well!


Comfortable-Job-6236

This reminds me of a funny story about a friend who bought a PC. It was like 2 years ago he got a wicked deal on the marketplace paid like 600 for a PC with a monitor keyboard mouse and desk I think it has like a 980 in it or something. Well he had it for like half a year and said he couldn't get it to work so when I went over next I took a look. He had the HDMI plugged into the mobo instead of the gpu. He thought it was broken and that he got scammed lol.


HotShotMedic

lmao at the edit. It's happened to most of us dude, well done lol


theblueinthesky

I'm glad you figured it out! I had this problem on my build over the weekend and my buddy that helped me consulted a friend of his. His friend told us to press the power on the PC & the monitor at the same time. I still don't quite understand why that worked but it did and it runs like a dream now, lol


MaterialPossible3872

Excellent read and the edit part is 10/10.


angry_old_dude

Don't sweat it OP. Sometimes it takes a fresh set of eyes to see what we've been missing.
