PC freezes intermittently, and only option is to hard reset with power button.

[vortex1]

As the title says, my PC freezes/crashes and the active application(s) are frozen on screen. The mouse is unresponsive. I have to restart by pressing the power button on the case. The active application(s) when it occurs is random. The PC displays normal CPU temps in HWiNFO64.

This problem is occurring quite frequently, and can't be put down to normal PC operation/behaviour.

I have previously replaced the PSU, so I don't think it's that. I have tried a BIOS downgrade but it still occurred. I have tried putting the RAM into default/removing XMP. I also ran a MemTest, and that came out normal. I changed the Windows 11 Pro boot SSD to a new one (cloned boot drive with Disk Genius). My iGPU & dGPU is running up-to-date software. Windows is up-to-date, and all drivers are up-to-date. I have run the system file checker tools - all to no avail. This is really giving me the runaround!

Does anyone have any idea what I can try next - without buying all new components and building an entirely new PC?

have you looked at your event viewer to see what errors are coming up?

Thanks for bringing this to my attention. I am working through the errors I see, and only time will tell if I get a re-occurrence of the freezing on the system.
