I just installed this motherboard in a case with an Amd xp 1800, power supply and 512K ddr 2100 from a different system that was working great and I can't get it to boot. If I set the jumper for cpu at 133 I have no video and the system shuts down in about 5 seconds. If I move that jumper to 100mhz it will allow me to get to the setup program and then shut down after about thirty seconds. If I skip setup it will boot until I get a message telling me there is a O/S problem. The hard drive is a WD 60 G that has been cloned from the Dell computer it is to replace. Could there be a problem with the fact that the old mb had an Intel chip set and the new one uses the Nforce chip set? I have tried using only one stick of ddr and swappinp slots without any change and nothing seems to be getting hot and all fans are running ok . There are no pci cards installed as this board has everything onboard. Anyone want to take a shot at this problem?
