Sounds like a possible timing issue. If you havn't already, go through tne usual DPC reducing procedure (power saving off etc).
Try one of these 4 configurations:
HPET enabled in bios + bcdedit /deletevalue useplatformclock
HPET enabled in bios + bcdedit /set useplatformclock true
HPET disabled in bios + bcdedit /deletevalue useplatformclock
HPET disabled in bios + bcdedit /set useplatformclock true
Run WinTimerTester 1.1 to verify your QPC and GTC are equal (ratio of 1).

Actually, this might or might not be unrelated, but I had some issues with my windows 7 x64, where sometimes the entire GUI of windows would stutter, setting HPET enabled in bios and useplatformclock true on, it removed those issues
However, it did drop my performance in all sorts of stuff, timedemo in cs 1.6 for example (you can get the demo file on satanion.dk/cs
) went from 1100 to 650, other programs that uses graphics showed a drop aswell.
For reference im on a ASRock z68 Extreme4 with bios 1.50, with a 2500K 8GB ram, and a GTX 560 Ti, its kinda.. lol when 1.6 lags for me
