Hey I have a computer that I want to sell for some money and everytime I unplug the power cord it loses its bios settings. It dont do this when i turn the computer off and leave the plug in. I changed the battery and it still does it so i aint to sure what it is. I was wondering if changing the power supply would work? I have a new one that has never been used that came from a computer case my friends uncle got. Anybody have any ideas if the power supply wouldnt do anything?
