Re: Computer won't turn on - grounding problem?
To reset your BIOS: unplug your PC from the wall, and press the power button a few times to drain any excess power. Remove the silver coin-shaped battery for about 30 seconds. Reinstall the battery, plug back in, and try to start back up.
If the PSU isn't giving it enough juice, then it's possible for it to turn on for a second then just shut off. You don't have any PCI cards, HDD's, or disc drives plugged in, do you? If you do, unplug them to eliminate those variables.
