Solved: Computer keeps shutting on and off; no Bios access

[gohanrocs12]

I was updating drivers and i had installed a bluray rom drive and my computer froze a few minutes later (mouse and keyboard looked powered but nothing would move, had facebook open and game was still running, and it happened before when i was installing a utility from my motherboard that came on the cd with the motherboard, it was either On/Off Charge Technology or AutoGreen), so i restarted it (did the same thing first time it happened and computer started up fine). Now it just keeps powering on and off over and over again in 2-3 second intervals WITHOUT STARTING THE BIOS. i checked if it might be the power supply (600 Watt), but it works on my other computers and i tried some other power supplies from my old computer (which is 300 watts i think) and from my dad's Dell (350 watts i believe), and i unplugged everything to see if i could just get the bios to run, but it was still doing the on/off thing. is it a problem with the motherboard?

I built the computer myself.

Did you try reseting the bios with jumper/battery on motherboard?

I took the battery out for like 20 minutes as i dissassembled everything. but it still does the same thing after i put the battery back. i'm gonna try the jumper later tonight when i get home from work, but any other ideas in case that doesn't work?

Maybe check the power button or check nothings shorting it out inside case.

Thanks for your help, turned out my motherboard died somehow....even though i bought it last week, exchanged it for a better one today, everythings fine now.
