Yes. The CPU alone will not handle some games. However, as the computer had the same problem when running the test using OCCT, the games themselves are not the determining factor for instability.
Therefore, if during the CPU test, the computer works stable and after that it remains stable, it is certain that the GPU is the cause of the instability.
For a more reliable result when using OCCT, perform the combined test by choosing all stability tests. Click on "Combined", check the box for all available tests, and click on the "Start" button.
