I recently traded processors on exact motherboards on different units one was a 2700xp the other was a 1800xp, when i installed the 1800 onto the cpu that was running the 2700 the system wouldnt boot, then i cleared the bios, and had to re-activate windows but after doing so the systems restarts after every boot and is never able to log on and i get a page fault in nonpaged area blue screen message?? can anyone help to get this processor to work in the other computer??
