Hi,
Keep in mind that if you are running very high demanding games for both CPU & GPU, it could cause overheating without damaging the hardware.
If the temp exceeds a certain level, then Windows are automatically shutdown to prevent any HW damage.
Donwload CPU-Z or GPU-Z or Speccy or HW Monitor and observe your system temps before and after gaming.
If the issue is not coming back, then it should be ok.
What errors did sfc found??
From an elevated cmd, (Run as Admin), paste this command:
findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt"
It will create a shortcut in desktop which you can open with Notepad.
Then you should see the sfc errors in detail.
Post back.
Regards,
