Clearing your motherboard's CMOS is a common troubleshooting step for dealing with peculiar hardware behavior. Because the motherboard controls the interaction of your hardware, troubles with the board can cause a variety of strange problems ranging from computer crashes to cooling fans that never slow down. Resetting the CMOS on an A8V motherboard may just resolve whatever problem you're dealing with.
Close all open applications and shut down your PC.
Flip the computer's power switch off and unplug the power cable from the back of the computer.
Press the “clr CMOS” button on the back input/output panel of the motherboard.
Hold the “DEL” key upon start up to re-enter your preferred BIOS data.
- Clearing your CMOS will not remove any files or data from your operating system, but will return your BIOS settings to the factory defaults.
