My PC constantly freezes if I'm not playing a game or have a game running.
✅ If I'm playing a game, it's fine.
✅ If I have a game running in the background while doing other stuff, it's fine.
❌ If I leave my PC while playing a game and the lock screen pops up, it will freeze.
❌ If I do anything other than gaming, such as browsing the web or digital art, PC will freeze.
❌ If PC goes to sleep overnight, it will freeze.
The frozen PC will typically show no error code and display will show "no input" until I hard reset.
If I hard reset, it often won't successfully turn back on unless I move the mouse while it's resetting, otherwise it will freeze again on the windows loading screen.
Sometimes I will actually get a blue screen with the error code of DPC_Watchdog_Error or something like that.
Anyone know where I should look first to try and fix this? It's been happening for weeks now and it's driving me crazy. I can't figure it out.
Reseat your GPU port.
Soumds like a hardware issue.
I've tried reseating it, as well as my hard drives and all power cables / PSU cables. Haven't tried PSU yet though or ram, probably will try that next.
Have you tried Debian live?
(For testing reasons, not trying to make you switch.)
Everything here points to a hardware problem, yet I had a similar issue that also was "fixed" by keeping a game running in background, and it turned to be out 100 % software. (Not fixed by putting the SSD into an entirely different system, but fixed by complete reinstall.)
Try running Debian live then.
