I just switched out a bad Asus a7n8x-deluxe for a new Abit nf7 and am running an Athlon XP 2400 with 1GB of RAM in a case with a 550W power supply. Since installing the new MB, when I pull up the Hardware Doctor tool, it shows the -12v voltage reading as -13.x (where x is between 1 and 9). Is there something that may be causing this?
