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.
Boot in safe mode, see what happens. Sounds to me like software conflict. You might try uninstalling your video drivers with DDU.
If you can work in safe mode, get rid of a couple of drivers, run DISM and try once more.
If you can't work in safe mode, boot from usb with hiren's boot disk. If you can't work in hiren's, reset bios to optimised defaults. If you can't work in hiren's after that, it's a hardware issue.
