I'm having a frustrating issue with my PC crashing unexpectedly, and it immediately turns back on. This mainly happens during gaming, and I can't find any helpful information in the Windows Event Viewer. I suspect it might be a power supply problem or possibly an issue with a Windows update. Here's what I've already tried:
- **Operating System**: I did a complete clean install of Windows and reinstalled all the drivers.
- **Virtualization**: I disabled all virtualization features, including Hyper-V and Windows Memory Integrity.
- **BIOS/Firmware**: I updated my motherboard's BIOS to the latest version.
- **Memory**: XMP was disabled, and I ran MemTest and Windows Memory Diagnostic without any errors.
- **Storage**: I checked the health of my drives with CrystalDisk and everything looks normal.
- **Power Supply**: I reseated all the connections.
- **Temperatures**: While gaming, my CPU and GPU temperatures are around 50°C.
I'm looking for any insights or suggestions on how to tackle this problem!

It sounds like you're really thorough with your troubleshooting! Those temps are indeed pretty low for gaming, which might suggest that power issues are at play, preventing your CPU and GPU from reaching full potential. Since you've reinstalled drivers, double-check if your GPU driver is up-to-date; it might still be causing issues. A crash dump analysis could help pinpoint the problem, but you might want to check your event viewer again for any new clues as well. Good luck!
This sounds really annoying! Have you considered that it could be a faulty power supply? If you have an extra one lying around, trying that might help rule it out. Sometimes even with normal-looking temps, the PSU can cause these kinds of crashes, especially under load. Keep us posted!
I haven't tried swapping the PSU yet, but it’s worth a shot! I’ll see if I can borrow one to test. Thank you for the suggestion!

Thanks for the tips! I checked the drivers again, and they’re all updated. I’ll look into performing a crash dump analysis next, just to be sure. Appreciate it!
