Re: overclocking nightmare
PULL THE BATTERY OUT TO RESET CMOS PROPERLY.
Let it sit for 10 minutes (more can't hurt). Go eat a sandwich or something. Pop the battery back in and report back.
Make sure the power plug is removed when you do this and press the power button a few times to drain any power left on the board.
