I've read a bunch of threads with similar problems, and i've tried them all, still won't do anything for me.

A friend let a friend of his build his computer. - Bad idea.

Thermal paste got on the PCP board of the CPU, not sure if that causes a problem or not.

I go to turn the PC on and it starts but turns off, no post, nothing. Just shuts off. I took every component off one by one, each time the same, no beep codes either. Even with no RAM in. Used 3 differen't PSU's that i know work.

Right now it's bench tested, nothing but the bare minimum on. PSU, Heat sink,CPU,Ram. Tested it without the heat sink as well, still nothing. Even reset/cleared the CMOS, still the same thing.

Could it be a bad mobo or cpu?

If there's TIM on the motherboard its probably causing a short. Get some q-tips and denatured alcohol to clean it spotless. Be sure to remove the motherboard from the case, and remove all memory/processor. Don't be shy with the alcohol, it evaporates quickly. Or purchase a special electronics degreaser like this - http://www.mouser.com/ProductDetail/3M-Electronic-Speci...

I cleaned it spotless, still does the same thing, is it possible it completely fried the system?

If you didn't clean it spotless before you supplied power to it - you probably shorted both the CPU and Motherboard

What did you clean it with?
