I was playing Cube World the other day and my screen blacked out, and I thought it was a one time thing so it happened like 2 times afterward so I stopped playing Cube World and my screen did not black out. I thought it was the fault of Cube World so I did not play it. Then I played Minecraft, Counterstrike, Left 4 Dead 2 without trouble, but after a few days I played Minecraft, and my screen blacked out. I couldn't use Control+Alt+Del because the computer was not responding, and when I was on Skype and my monitor blacked out, the Skype just faded away, and I could not hear anything. Now if I'm listening to music on YouTube, the song get stuck and makes an annoying sound, but when doing tasks like watching YouTube my monitor barely goes dark, so it goes dark when it is running the heavier tasks.

Seems like a graphics problem or a heating problem. – Doktoro Reichard Aug 25 '13 at 23:09
I was going to suggest that you may be accidentally hitting a hotkey that puts the monitor in standby mode (this happens to me sometimes when I’m typing too fast), but that it actually freezes the system (as evidenced by the fact that audio gets stuck in a stuttering loop and pressing Ctrl+Alt+Delete doesn’t work), as well as the fact that it only seems to happen when doing more intense tasks like 3D gaming definitely points to a heat problem. Have you checked your system temperatures? You’ll want to check the temperatures of the system, video-card, and CPU. – Synetech Aug 26 '13 at 0:15
If im watching a youtube video its like 40 - 50 C When playing a game it goes higher so its around the 60 c – Eddie Aug 26 '13 at 12:38
