Dear Linux gamers, I need your help.
My son's gaming pc sometimes hangs up. The screens go black and into standby, all fans go off, but the power LED stays. Both the reset and the power button on the case have no effect at all. The only thing that works is completely cutting the power (via the power supply's on/off switch) and waiting for half a minute. Then we can turn it on again without issues.
- The buttons are working in general, i.e. unless those blackscreens occur we can power on/off or reset the machine without issues
- Memtest did not find errors
- Exchanging the RADEON GPU did not change anyhting
- New linux user account: no change
- The SSDs are fine (smartctl)
I have been building my own PCs for 25 years and never had an issue like this. Especially as the hardware buttons do no longer work, that completely confuses me.
OS is Nobara Linux 43. The freezes seem to happen most often when starting a game in Steam (or re-joining a game).
