Hello all, As all of you know, I love to push my hardware to the limits, risking thousands of dollars of computer just to see how fast it can go. Er, I mean overclock. But I have an issue. Every single time I overclock over 265MHz FSB, I try to boot to Windows and it ends up with a message that system files are missing, and that I need to run a rescue installation to get it back. Of course, I'm not going to do that, and once I clock back down below 265 Windows boots fine, even at 264MHz but not 265. Anyone know if I can treat this with a setting in Windows or my BIOS? I haven't tried to boot to safe mode yet, and I haven't tried a couple settings in my BIOS I think might help either, yet. Is this just how Windows works, you can't run a CPU 850+MHz over it's rated speed? Something involving the Device Registration?
