I have a pc with a 2.0ghz Celeron processor and Asrock MB. It seems to hang every so often or restart. I checked the temp of the CPU in the bio at it was running hot at 76 degrees Centrigrade. I cleaned the old paste off the CPU and replaced it with some decent stuff. It then reported lower temps for a while but then reverted to the same behaviour.
I've checked the temps in the bios and they are back up to the former levels. I have also noticed that the heatsink is very hot. I know that is its job but it seems way too hot to me; almost too hot to touch. This machine is not overclocked in anyway and is only running a fairly low spec processor.
I'm currently using the Universal Boot Disk to test the CPU and other settings..
What could be causing this high temperature and is this is as I suspect, the cause of the erratic behaviour?
