A week or so ago one of my friend bought a load of parts to upgrade his computer including a new mobo and processor. A day later he came in and said it wouldn't work and I offered to take a look at it thinking he didn't seat the DDR correctly or something of that sort. He demanded to take it to CompUSA for them to look at it and fix it.

He came to me on monday and said it wouldn't work because the processor was broken. I asked what was broken. He replied

"When I was putting the thing with the fins on the processor the instructions said to put some of the white stuff it came with on it. It disn't say how much, so I didn't put any on it."

You can assume what happened, and that he RMA'd everything for new stuff. I'm kicking myself now for not being more demanding to help him. I guess I'll have wait for the new parts to come to show him how to do it right.
