Clear the cmos and that should get you back to factory defaults:
Clearing The CMOS
Clearing RTC (Real Time Clock) RAM: Notes: Some motherboards use different key combinations to enter the bios setup menu.
- Turn OFF the computer and unplug the power cord.
- Hit the ON button (power button) on the case to remove any residual power.
- Remove the onboard motherboard battery.
- Move the Jumper Cap from pins 1 & 2 (default) to pins 2 & 3. Keep the cap on pins 2 & 3 for ten seconds, then move the cap back to pins 1 & 2.
- Reinstall the Battery.
- Plug in the power cord and turn on the computer.
- Hold down the DEL key and enter the bios setup menu to re-enter data.
There are also some motherboards that you can simply push a button to achieve the same as moving the jumper from pins 1 & 2 to pins 2 & 3 and then moving the jumper back.
In addition, there are some boards that you simply use a screwdriver to short across the two jumper pins (no jumper), but this serves the same a removing the jumper and replacing it to adjacent pins.
