Unplug the power cord from the PC. Open you're case & find the 3.0v battery on the board. Use a flat tip screw driver & remove the battery. Wait about 15 seconds & replace the battery. Close the case & plug the power cord back in. Boot the PC. You will need to enter the bios to reset the clock settings & any other settings you may have made. Thats it.
