No it won't be shot, don't worry strikeking17. As long as you don't overclock too high, you will never get a lasting damage effect. It can usually easily be reset back to standard clocks.
Do what lhuser states with resetting the bios by removing the battery and taking out the power from the wall socket, and then after a while placing it back.
On some motherboards, there is a CMOS jumper, that basically does the same thing, but ALOT quicker.
Check in the manual if you have it, but if you do, its this connection, almost like the jumper on the back of a hard drive, that uses a piece of plastic with metal connectors (the jumper) to make a connection on the desired function.
If you move this from its standard position and to the other secondary position, the power will be removed from the battery and it'll be wiped almost simultaniously. Though leave it like that for a minute to be sure, and then simply place the jumper back.
I hope this helps
