I just bought a new Biostar P4M900-M4 motherboard for Intel Celeron processor. I also had to buy a new stick of RAM to fit in the new motherboard. When I go to boot it up I get this message: " Warning! CPU has been changed or CPU Ratio changed fail. Please re-enter CPU settings in the CMOS set up and remember to save before quit. " The thing is that I cannot do anything at this point, it almost seems as if the keyboard doesn't work and I cannot enter the CMOS set up. Its a ps2 keyboard I was going to try to see if a USB keyboard would do the trick I just don't have any in my office. Does anyone have any ideas of whats going on?
