What does that mean ?
If you have a reboot, a BSOD, or a power off : your computer is unstable. It does not come from OCCT. And in the power supply test, which is, again, VERY aggressive, that means your PSU cannot give enough power to your other components.
The PSU test IS hard on your computer, again, beware.
Also we may have bugs in OCCT such as "the test isn't starting" "it's ignoring some parameters", if you have a BSOD, a poweroff, a reboot, or such : you've got a hardware problem.
My advice : do not play too much with this test on your computer. A poweroff usually means "the power supply went on protection mode" to avoid killing itself or other components... More : change your power supply if you want to be sure everything will be fine afterwards.
