I currently have my 700E running default voltage @ 1050mhz just fine in Windows 98. I can also run Windows 2000 just fine. However, when I run Counter-Strike within Win2k, I got a blue screen error and the computer spontaneously rebooted after 10 minutes. This never happened in Win98. Is Win2k more "sensitive" to overclocking? I have a suspicion that my memory might be causing the problem.
