I am working on a friends PC, he brought it to me with the CPU and the heat sink in a plastic bag...not a good way to start things out. According to him a blade from the fan on top of the heat sink broke off and rocketed into the CPU destroying it. He of course tried to yank it apart and in the course of doing that discovered a small burn in the CPU socket, it blackened and warped the socket in only one receptacle- nonetheless the mobo is fried as well as the CPU.

Getting a replacement motherboard and CPU aren't the difficult part, my only real problem is discerning the reason this happened in the first place- all signs (to me at least) point to a short, and in that instance where did it come from? the power supply? This leads me to the question of whether the power supply is compromised or not- which would drive the cost of repair up even further.

Is there any way that I can find out what happened and where that short came from (if that is indeed what burned the socket and cpu)?

First to say,"Gotta see pics of this".

I don't see this happenening the way your friend laid out the sequence of events.

"discovered a small burn in the CPU socket, it blackened and warped the socket in only one receptacle"---What does this mean? Just one pin?

What causes a burned socket? Usually bad contacts, overvoltage+overclocking (cough, Foxconn Socket 1155, cough).

I am a retired Ford tech. Next to Fords, any computer is a piece of cake. (The cake, its not a lie)

Yeah, just one pin is burned but while I was taking pictures I discovered that there is actually a pin to the left of the burn that is stuck in the socket. I never put HP past anything (I have had bad experiences with their hardware choices before), but I think this may be over voltage from a power surge...hell, for all I know he opened it up when it was still plugged in and on. My friend doesn't really know his way around a computer so I think he could have yanked the heat sink and CPU out without knowing he was committing PC homicide.

Is there a way that I could test the power supply to know if it is fried?
