Whenever a processor is either bad or on its way out...i know for me..i always get some very weird errors. I would look into making sure all the pins on the processor are straight....if that doesnt work....i suggest just hooking up the PC with the bare essentials...1 HD...1 CD drive....if it's got built in video and sound..then just leave them.....then add stuff one by one if there's extras to see if it's a hardware failure.
