I have an Asus P4G8X skt478 motherboard running a P4 1.6Ghz chip, I have managed to get a P4 2.8Ghz chip with a FSB of 533 that tallies with my motherboards specs but when I put this chip in my p.c will not power up, the fan spins for a second the stops. As far as I an aware the new chip is good but I cannot check this and when i reinsert the old chip and check the bios i cannot manually change the processor speed , it seems to be stuck on 1600Hz and mentions something about changing the board to jumperfree, can anyone help?
