Need Help Asap!

My computer specs are:

Motherboard: Gigabyte GA-8S648FX
CPU: 3.0 p4 Northwood
RAM: DDR400 1GB, Corsair and Elixir
Video Card: 8X AGP XFX 6800XT 256 mb, 256-bit
HD: 7200 IDE 250GB Western Digital
PSU: Antec Truepower 2.0 550-Watt

I just recently re-installed windows XP sp2 and everything was working beautifully. I got curious and wanted to see how far I could overclock my computer and read through my motherboard book. I went into the BIOS and enabled the "Top Performance."

When I rebooted the machine, everything seems to work like it should, but my montior receives nothing and I get no display. How do I go back and changed the settings on the BIOS to make it like it was?

PLEASE HELP!

Unplug the computer from the wall. Open up the computer. Touch the power supply to ground yourself, Look or the little cmos battery that looks like a nickle. Take it out for a minute or so, put it back in, plug in the computer and fire it up. Everything will be set to defaults.....

Please don't overclock. #1- it voids any warranties. #2 - unless you know exactly what you're doing you can destroy your CPU , RAM, and other components.
