I have an ongoing problem that my desktop PC shuts down intermittantly and CPU and PSU fans spin full blast on shutdown after Windows 7 has finished shutting down and the black screen is showing on the monitor. The only was to completely shut it down is to do a forced shut down by holding in the power button for a few seconds.
I bought the PC as a refurbished item and the Base Wty: HP HW Wty: Maintenance Onsite Support and Wty: HP Support for
Initial Setup have both expired on this PC.
I have tried various things to fix this issue in case the issue is to do with the PC overheating:-
Changing CMOS battery
Replacing thermal compond on CPU
installing a case fan on CPU
Lowering thermal setting in BIOS
Replacing the PSU
Reinstalling Windows 7 Pro
Checking PC for Virus's and malware
Please can you advise on how I can resolve this issue?
