PC won't boot at all

[lord filbuster]

I was just playing test drive, and the pc locked up completely.
So, i reboot, and the pc starts, runs for about 2 seconds, and powers down.
i try again, this time it seems to be normal, gets to the post screen, then powers down. i then cleared the cmos, and left it for 5 minutes, same thing.
now it will just power on for a split second, and switch off. could it be a grounding problem? i will try reaseating the motherboard, it doesnt sound like it is overheating, as the temps were ok before it crashed. I will try disconnecting some things to see if it is the psu, does anyone have any other ideas?

Leave it unplugged from the wall socket completely for a few minutes

Ensure the motherboard and such like are in good appearance (no burn marks etc)

Remove *all* unessential hardware (sound cards, unneeded hard drives, TV cards, web cams etc)

Remove graphics card and try to boot it

Try another PSU

Reseat motherboard

Agreed

Hi There
It does sound more like a psu issue to me. If you can get another one from a mate, just plug it in and see if it works.

no, it isn't the psu, i took everything out, no luck, then i just reseated the cpu heatsink, and it is fine, running now, temps are still reading the same as they were before though. i have absolutely no idea what caused that. But still it's fixed now i guess.
