Can anyone help? I have put in new bios for this board for a friend (so he could use a bigger hard drive). The new Bios version is F3A. Now the pc wont boot at all. When I turn on the pc (dont have to use the button at the front now it comes on when I turn on the psu) it just sits there on a black screen. It doesn't beep and dousn't get to the bit where it detects the hard drives and stuff. Please help.
