anybody know any good overclocking software that won't screw up my comp?

I don't know if there is much in the way of software, or if it is done all through the BIOS (although I really don't know much of this topic)

Look at your BOIS options for settings for FSB speed (or bus speed) and CPU Multiplier. (CPU speed = Bus*Multipler)

If that messes up your computer so much you can't get back into BOIS options, then either, if the computer is a custom build, look at the motherboard manual for how to reset the BOIS or remove the BOIS battery.

If you have a GeForce card you can overclock it using a registry entry you can download as a reg file and merge into the registry, do a google search for coolbits

I think that overclocking is BAD. Your hardware is designed to run at certain settings. By changing those settings, you put extra stress on the hardware. This shortens the lifespan of your hardware. With computer hardware so cheap these days, you're better off buying an upgrade.
