When loading windows XP the normal windows loading screen comes up with the blue bars running across the screen and stops scrolling the blue bars and freezes my system. The next time I restart the system the bios cuts in with a message saying " During last boot up your system hung for an improper CPU speed setting" I am using a Asus A7A266 motherboard with an athlon 1800+ cpu speed 1533mhz , multiple 11.5x , pci freq. 133/33,bios revison1008. I have also tried to use another hard drive with windows 98 open in safe mode this will open windows and work for a short time and then freeze again. Can anyone please help?
