W1zzard: Thanks for the info. RealTemp does try to calibrate QueryPerformanceCounter with GetTickCount but I know there's room for improvement. I have access to a board this week that I think has this issue so maybe I can improve how RealTemp handles this problem.

Daddyjaxx: Check out AutoRuns. It lets you find every last hiding spot for applications that start with Windows and is a big improvement over msconfig.

Without AIDA64 running, my second computer has been stable without a single lock up . I also haven't had any other reports of RealTemp problems so try completely removing AISuite and see what happens.
