Computer shuts off at bios screen

[kyleaikens]

My computer shuts off after a few seconds on the bios screen..

I jumped it lastnite, it worked all night. I turned it on this morning, and it does the same deal where it shuts off after a few seconds of booting.

Any ideas?

Check if the cpu heatsink sits properly, maybe the mounting pins came loose and the cpu is overheating and shutting down.

Some boards have a method to detect if a heatsink is correctly attached to the board. Smae deal as above - check if heatsink is mounted fully. You could try taking it off and puttting it back on.

Are there any messages showing up in the BIOS that suggest problems?
What PSU have you got?
