  1. when i turn off my pc without unplugging it everything works fine, but when the computer has been unplugged it asks me to re do all of my bios settings, could this be because of my motherboard or maybe an Bios Update?, Please help...

    Try replacing the CMOS battery on the motherboard. It will be a flat coin-like battery.

    I have tried 3 different batteries but they all still have the same effect, i have no clue what could be causing the problem, maybe my motherboard?
