When you have a problem with your BIOS or other motherboard components, clearing the CMOS might make your P5K-VM motherboard work again perfectly. Your CMOS battery feeds the BIOS and other components of your motherboard while the system doesn't draw power. To make sure your CMOS gets cleared, remove the battery after you turn off the computer and remove its cables.
Instructions
1. Disconnect your computer's power cable and peripherals.
2. Turn the computer with the back facing towards you and lay it down on the left side.
3. Remove the screws from the edge of the side of the computer that now faces upwards and take out the panel by sliding it outwards and upwards at the same time.
4. Locate a small battery near a red and wide IDE connector on your P5K-VM motherboard.
5. Get a flathead screwdriver and lever the CMOS battery out of its socket and keep it out for about half-an-hour. The capacitors must drain power before you stick it back in. After the time has elapsed, pop the CMOS battery back in and reassemble your PC. Your computer should have a "good as new" CMOS.
