The CPU is a specific component within the computer, its no bigger than a cell phone.

What reasoning did your friend give, for thinking it was the PSU?
Have you tried trouble shooting the issue on your own yet? If so what have you tried?

Could be an overheating CPU.

StickMan could be right. This sounds like a very unscientific and unsanitary exchange of CPUs, without such niceties as cleaning off the parts and reapplying new thermal paste.

OTOH, what exactly is TS's definition of "CPU"?

This could sound like I'm advocating smearing "Arctic Silver" all over a motherboard....
