Freezes During Sandra Benchmarks

[PC_User]

I decided to just run some benchmarks in Sandra. However, when launching the CPU tests or Performance Index test, the system keeps freezing. What could be the problem? Could it be that SpeedStep is not kicking in when it needs to? Potential system instability? I've never had a single crash before (after initial stability tests).

Edit: Just ran the program's Burning-In Stress Utility and it was fine.
