I don't know what's wrong. My computer was on a bench and I used thermal paste (probably too much of it at first) and my computer still worked. But after I put everything back in the tower it didn't boot up.
I took the CPU out and noticed that some bits of it got on the chip but not the side that touches the pins. Did this damage the CPU? And I also didn't wear any grounding gear, did I static shock it? I held it by its sides with my bare hands (though it was still working after I held it for paste the first time).
I put the CPU and fan on another motherboard and still it doesn't boot. And it worked fine before and after putting thermal paste on. I tried as suggested by some to lessen some of the paste and clean some of it off the CPU's top metal plate, but still nothing. Is it ok to clean the chip part of the CPU with rubbing alcohol? What about the side that touches the pins?
Another question: Putting the CPU fan back on feels like I'm putting a lot of pressure on the board, does this damage it?
Any ideas? Did I kill my CPU?
