OCCT is a Windows application to check the stability. It enables you to test your computer'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 indefinitely, 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 see how your computer's temperature rise from an IDLE state to loaded, and the other way round. OCCT also embeds a monitoring engine, giving you readings of the computers inner temperatures, voltages, and fan speed, and displays them in graphs plotted in real-time. OCCT even protects your computer from overheating or damage by including alarms you can customize for every sensor: once you go above (or below) the alarm value for a temperature, voltage, or fan speed, the test will stop to protect your computer.
