I've had this problem occur once before, but it fixed itself after I removed the power cable and reinserted.
My computer will start up, I hear the hard drive start to spin, all internal fans start up, then the computer turns itself off after anywhere between 3-10 seconds, then turns itself back on after ~3 seconds again and repeats the cycle.
I don't think it's a faulty PSU, as I have a TV tuner card with a LED which stays on at all times. I think it may be a problem with the graphics card, as before this problem began occurring, the computer crashed twice while on a resource-heavy game, then BSOD'd with a memory error.
I've tried starting with the hard drive unplugged, and nothing happened differently (minus the lack of the drive indicator light). I can't remove the graphics card at the moment, but I'll try ASAP. I've also tried removing my TV tuner card, but that also made no difference.
The only modification I've made to my motherboard is to flash it with a more updated BIOS, however that was several months ago and no problems occurred then.
Specs:
Edit: Forgot to mention, it never gets to POST, it appears to restart just beforehand.
Edit 2: Occasionally it will stay on to emit a series of beeps. I can't tell if they are long or short, though I assume they are short, meaning there's something wrong with my power supply. I'll check it out with a friend of mine.
