Are you sure that your system is stable under all conditions ?
Please try the following test:
1. Set one of default win10 screensavers (preferably animated, eg bubbles, 3D text) to activate in 2 minutes
2. Run RealBench stress test for 30 minutes
3. Relax a little
After 2 minutes ScreenSaver should start, but nothing should happen, or be very very slow.
Now watch, if the animation picks up speed, RealBench has aborted or finished.
Check the results.
I have tried it on two PC's, both fail within 10 minutes 😞
But can pass RealBench stress test for hours if SS is disabled.
