So I am upgrading my motherboard butt, It wont load.... It will load to bios with no problems but when XP is trying to boot up it turns off. So I try to repair xp by by the disk in first and as setup XP is loading it turns off, I have already verified I have the correct PSU I have 400 while it only requires only 300 or 350 my my cd drive, hd drive all work fine as my old motherboard operates fine.... I don't think their is a problem with my mother board or cpu as it works fine in bios, any help is greatly appreciated.
