I've been experiencing a frustrating issue where my PC restarts unexpectedly after about 1 to 2 hours of gaming. I've checked for overheating and file corruption, ran SFC and DISM, and even tested my RAM—all came back fine. I've also uninstalled and reinstalled my drivers, but the problem persists. I thought it might be the PSU, but that's not it either. In the event log, I found a message stating that a critical component has failed and my device isn't expected to pass attestation. Here are my specs:
- Windows 11 Pro
- AMD Ryzen 7 5700X
- RTX 5070
Any ideas on what could be causing this?

Sounds like you're dealing with a hardware issue. I recommend swapping out different components to see which one might be failing. There's really no perfect way to pinpoint intermittent problems, so testing is key!
You should check the Event Viewer in Windows 11. Right-click the Start button, select Event Viewer, then navigate to Windows Logs > System. Look for critical or error events around the time of the reboot. It might give you clues on what went wrong right before the restart.

Thanks for the tip! I checked it out and realized I just needed to update my BIOS—who would have thought?
