OCCT (Overclock Checking Tool) is a tool for checking the stability of your system by running four tests, aimed at testing the processors, graphics processor (GPU) and power supply. OCCT also monitors temperatures, voltages, Wattage, fan speed, as well as system constants such as CPU utilization, memory usage, etc. You can set the duration of the test (indefinitely or limited to a certain time).
Please note, however, that the duration of the test for the free version is limited.
Results are displayed in real time and can be saved as graphics (PNG format).
With OCCT, you can find out which component is faulty, and save time by proving to the after-sales service, for example, that your equipment is faulty. I can't promise you that it will go smoothly, but at least you'll have proof that you've done the right thing!
Bear in mind that OCCT has been designed for advanced users.
