Repair Bad Bios Flash

A motherboard holds all the central parts.

The BIOS is firmware instructions that the motherboard uses to connect all the devices and boot up the computer. Frequently, a motherboard manufacturer will update the BIOS so that the computer gains more functionality and errors are fixed. BIOS updates are important and critical to the longevity of a computer system and motherboard. A power surge or another complication could cause the BIOS update flash to end prematurely, causing a bad BIOS flash. Motherboards are equipped with jumpers and switches that help in these situations.


1. Unplug the computer from all the connectors. Unplug the power cables, the monitor cable, the keyboard cables and all the associated cables. Place the computer on a clean table.

2. Lay the desktop computer flat and follow the instructions for removing the chassis cover on the side where the motherboard isn't mounted too. Usually this requires the removal of two primary screws located on the backside of the desktop.

3. Remove the chassis and place it on the side. Refer to the motherboard manual on where the BIOS reset jumpers are located. Take a two-pin jumper and place it on the pins according to the motherboard specification. Each motherboard has a different type of reset mechanism and jumper location for your specific problem. The motherboard BIOS reset options are located near the motherboard CMOS battery.

4. Plug the computer back in and boot up the computer. The computer will beep notifying you that the BIOS has been updated. Remove the computer power cable again and remove the jumper to put the computer back to default settings. Now you can flash the BIOS and run a clean update again.
