OCCT is a stability checking tool that was created back in 2003, and was regularly updated since. It enables you to fully test your PC's stability, using 4 different tests : CPU:OCCT and CPU:Linpack aimed at testing the CPU, GPU:3D for the GPU stability, and Power Supply, a combination of CPU:Linpack and GPU:3D to fully load your Power Supply.

Each test can be run indefinitly, or for a fixed amount of time. You can even include an idle period at the beginning or at the end of a test, to better see how your computer's temperature rise from an IDLE state to fully loaded, and the other way round.

Version 4.4.2 is a freeware program which does not have restrictions and it's free so it doesn't cost anything.
