HELP: Computer shutsdown immediately

[enricong]

I have a tbird 1333ghz on a abit kg7-raid
Everything was working fine but my hsf was too loud so I replaced it.
When I push the power button, my drives and cpu fan starts spinning, but the computer turns itself off after about 2-3 seconds.

Any ideas what could be causing this?
I don't see any damage on the cpu core and don't think I used excessive force. I even have a cpu shim in place.

could there be another reason for this problem?

Does the system speaker beep at all?

Hey

When you replaced your HSF did the other one come with a compound patch on the bottom or did u add some thermal compound??

If you smeared arctic silver on the top of the chip, it may be causing a short. Clean the top of the chip, and put a small (smaller than that) amount of TIM on the raised surface of the die. This should clear the problem.
