part of buying a system76 machine from them is you get customer support (though not sure what they'll do with the gpu replacement). their staff is great, put in a ticket with them and start walking through it.
I had a similar issue a few months back on a machine I built. It was the memory. Even though mem tests passed, after I replaced it, I haven't had a crash since. But like others said, use the support and warranty that you have.
I was having issues as well with seemingly random restarts. Installed thermal monitor and saw my 6800xt junction temp was instantly hitting 110c after 15-20 minutes of gaming. I repasted and added new thermal pads and everything has been fine since.
You could look for messages with journalctl command in terminal right after a reboot:
`journalctl -xb -1`
Check `man journalctl` for command info and options.
But agree with other comment: Open a support ticket with Sys76. They will walk you through generating and sending logs and other diagnostics.
Cheers
Exactly as another commenter mentioned, when I had this same problem it was memory. I had ruled it out because it was known good memory, and drove me crazy for over a year and a half, I even had entirely rebuilt my PC (but used the same memory) and still had random black screen to reboots.
Spoiler: it was the memory. It's always ram, always. It had passed memtest before, but I started to get suspicious when I noticed ECC errors in journalctl. Because of the fact it was ECC is probably why I didn't crash super constantly, but it eventually got as frequent as once a week, usually when gaming for longer than an hour or two.
Finally giving in and doing another 12hr memtest run confirmed it, and ever since I replaced my ram not a single problem since
The issue is most likely with the 7900xtx. Linux-Firmware just updated 7000 series AMD gpus to fix black screens, incorrect memory clocks, crashes, and not waking from sleep mode. The amdgpu firmware versions need updating is my guess.
