ECS motherboards, like other motherboards, have a jumper on the system boards that allows you to manually reset the Complementary Metal Oxide Semiconductor (CMOS), a small internal battery on your motherboard that stores BIOS settings. By resetting the CMOS you reset all BIOS settings to the default values. You can reset the CMOS jumper on your ECS motherboard by opening the computer case and performing a standard jumper reset.
Instructions
1. Shut down the computer that contains the ECS motherboard you wish to reset.
2. Disconnect the monitor, power cable, mouse, keyboard and any other devices currently connected to your system. Place your computer tower on a clear workspace.
3. Open the computer case. To open most computer cases, remove the two screws along the rear of the left side panel of the case. Slide the side panel backwards, then lift it off.
4. Locate the BIOS CMOS jumper on the motherboard, usually in the bottom, right corner. The jumper consists of three metal pins facing upward and is usually marked with "CLR_CMOS" and has a plastic cap over two of the pins. Check your specific motherboard manual if you are unsure where the jumper is.
5. Slide the caps off the number 1 and 2 pins and slide them on the number 2 and 3 pins. Wait approximately one minute. This resets the jumper.
6. Remove the caps from the number 2 and 3 pins and place them back over the number 1 and 2 pins.
7. Reinstall the side panel and hook the computer back up.
