I have Gateway and Compaq computers that started shutting down randomly ( each at different times) a few weeks ago. I did a virus scan. I ran utilities to remove malware and spyware. I checked power supply voltages. I cleaned out all the dust in both units. I checked temperatures with Open Hardware Monitor. One unit is on a uninterruptable power supply so it can't be power surges. Everything seems ok but it still happens. Does anyone have any other ideas about what the problem can be?

The voltages were measured with a digital multimeter. The temperatures were taken from OpenHardwareMonitor as:
ITE IT8728F: 36C, 56C & 34C.

INTEL G630: 35C, 35C & 35C.

ST3500413AS: 39C

PSU's are hard to check. they must be tested under load.
