How to Test Windows PC for Stability with OCCT:

Two test lengths are available in this free computer stability tester, around the clock testing, which is where you leave the test to work in a loop all the time, and timed tests, where a test only works for a limited amount of time, for example an hour or if you want to be thorough, days.

OCCT started test

Select the test duration, pick the system type, 32bit or 64bit, modes of work, which is the type of data sets that are gonna be testing your system, and then click ON. After that use the monitoring window on the right to see that the CPU is fully loaded and is being tested. Make sure to track the temperature, so that it doesn’t go up too much, but there are alarms for that, like we said.

OCCT test report

Do the same thing for all the other available tests and once you think your PC had enough, your computer worked fine without crashing, click the Off button to stop the tests. When tests are finished, you’ll be presented with a directory where you’ll be able to grab screenshots of test results and diagrams, and thats it.


Certainly one of the most common reasons why computer crashes is when the fan; which is keeping the temperature down stops working and the CPU starts overheating. Computer then shutdown after a while to prevent damage, if something like this starts happening to you, OCCT is the perfect tool to test the stability of your system.
