The last 3 days my screen continuously "go to sleep" when I am actively using my PC. Moving the mouse or pressing a key solve the problem, but it does it randomly and very frequently. I solved the problem by not loading the power manager. A bug in the power manager? I tried to play a bit with the settings, but the problem persisted.
Here's my sistem:
