Well, I thought it was only a small temporary failure. I went into another game and the same thing happened to me ... So that day I stopped playing. I see a movie in my PC. All play, the display of the film was small rectangles regulars. To solve the problem, reinstall Windows. It seemed that returned to normal, but no. Se was still worse than before. I wanted to see if I can fix the problem, so I need help of others to you.

Until now I find out what the problem is the PC, not the monitor.

Characteristics of the computer that I know them by heart because I can not install anything for consideration:

No graphics card has. (Has a chip)
Operating System: Windows
-Brand: Packard Bell
-Hard drive: 250 GB

I had not installed any software or changed anything in the PC hardware.
