Trying to fix up a PC for a friend so don't know it's history. The CPU heatsink was plugged with lint so cleaned that out and cleaned and regreased the heatsink to CPU. PC is dead - no post, no video out, no activation of mouse or keyboard leds but fans run and it power supply goes on and off with front push button. CPU cooler is getting hot - not too hot to touch but hotter than expected. Tried a new power supply and got same result. CPU is AMD HD9500WCJ4BGD. Looking to get this going again without spending a much money if possible. Could pick up a used CPU for about $20. I have put together a number of PCs and have an electronics background but haven't had to do much troubleshooting to narrow down issues like this. Any thoughts on how likely the damage is CPU or motherboard or both?
What should I be checking? Core voltage on the mobo?
