Overheating PC?

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?

Reseat the heatsink to make sure it is flush and making good contact, and that the fan is spinning properly.

Otherwise, I think you have a defective cpu or defective motherboard.  A 2.0GHz Celeron should run cool to the touch; you can try this cpu in another compatible motherboard as a test, or swap in another cpu (they are not expensive to replace).

I've replaced the CPU with a spare and will report back in a short while...

Problem solved... Replacing the CPU seems to have done it. The temperature dropped by over 30 degrees C and has stayed around that mark. The heatsink isn't running hot enough to fry an egg on either.

Thanks for the help..
