My Windows 11 PC freezes randomly with no BSOD and no error messages. When it happens, the system becomes completely unresponsive, and I have to hold the power button to shut it down.
The freeze happens without any warning. I checked Event Viewer, but I can’t see any errors or critical events at the time of the freeze (for example, around 2:57 PM when it last happened). This issue started around 2 weeks ago. It mostly happens randomly during normal usage.
Before contacting here, I already tested the following:
- RAM:
- Windows Memory Diagnostic → Passed
- MemTest86 → Passed
- SSD:
- CrystalDiskMark → Normal
- Samsung Magician → No issues
- CPU & GPU:
- Prime95 (CPU) and FurMark (GPU) running at the same time
- I also monitored the 12V rail to check for voltage drops (it never went below 11.5V)
- The system was completely stable during stress testing
My GPU and PSU are almost new (about 6 months old):
- GPU: RTX 5070 Ti
- PSU: Corsair RM1000x
Even after all these tests passing, Windows still freezes randomly during normal usage. At this point I am not sure what to do.
