I've recently been having this issue too, out of nowhere. PC runs smoothly and multiple windows (game + a show on a different screen, or music, etc.) but after closing a game, it's been freezing my PC and either requiring a hard power off or hard restart

It sounds like a hardware conflict is causing the PC to restart to protect the operating system. Check Event Viewer system logs immediately after the PC has rebooted which might give an indication on the root cause.

Open Task Manager and ensure the box is checked next to 'Always On Top'. If this is checked you should always be able to bring Task Manager to the foreground if a game freezes with Ctrl + Alt + Delete to kill the process instead of having to do a hard reboot. If the PC is completely freezing and you can't even bring Task Manager to the foreground or cycle with Alt + Tab it could be something more serious like malware or a bad stick of RAM.

The games run smoothly at a high FPS but as soon as click "exit game" the screen freezes and then my PC shuts down and restarts immediately after. What is causing this and how do fix it??

Check own board support for BIOS update and its chipset driver and rest of the drivers you need.

You might need to run window update after this, ( depend on how many things that has change )
-----------------
Then that is done, dont get caught in own OS issue.

DISM.exe /Online /Cleanup-Image /Restorehealth
SFC /Scannow
chkdsk c:
chkdsk d:
chkdsk e:
------------------
Maybe even validate game intergrity of files, its never this, and yet there is always one steam user that need it.

+ latest Freshly installed GPU drivers, and VC++ check at MS own support page.

Alot of user seem to use previous druivers, this just tell us here you might not have a update pc. thats dont like newest driver. ( yes it can happend GPU card supprt make mistake, but i will say more rare then you did not have a pc thats update.

this is for windows user, standard advice.

Did you ever get a solution for this?

It started to happen to me lately. I close a game and the PC gets stuck and reboots, but in my case sometimes it doesn't boot back up and I need to remove the CMOS battery for some minutes so that it can boot again :(

What intel chip generation are you on? This could be due to the 13th and 14th gen voltage bug.

This can still be a intel chip issue. It does not matter if they use nvidia or amd. If they use intel chips, it can still be a issue with 13 or 14 gen chips. I had a friend who used AMD with intel chips on it.

The symptoms of it can mimic issues that also can happen with GPU's but it is more related to the CPU power voltage system. This voltage issue can damage hardware and even damage sensitive GPU's.

This is from goolge, copied:

"Motherboard Compatibility:
While you can use an AMD GPU with an Intel CPU, you can't use an AMD CPU on an Intel motherboard, as they use different sockets and chipsets"

Your probably thinking of the motherboard, but if they just use a Intel CPU chip without the motherboard, this can still be issues with the chip itself.

I actually as i said have many friends who use Intel chips with AMD stuff too.

software violation

hvy

you did something not allowed. whether you know it or not. can be a unstable overclock. thermal. malware. permissions. etc..

well, I don't recall doing any software violation. I've never overcloked, I will re paste the CPU in 2 days though, just in case.

And yes, my case is for a 13th gen i9 13900k with a an ASUS TUF 4090 OG on top of a Gigabyte Aorus Z790 elite ax, but I already have the Intel profile from the MOBO firmware. But yes, it could be it, I will re check the BIOS settings for it.

Thanks everyone. I'll update you here if I get to the root cause of my issue :)

Having this problem rn, any updates?

I FIXED THE ISSUE FOR ME. It was deleting gigabyte control center, idk why it was causing problems, or how, but i guess it was, and deleting it was the fix.

Nvm....:(

Happened to me a while ago, after a windows update ofc. Forced back windows to a previous version, and it went away.
Now windows forced an update on me and it is happening again :(
