Portable problem with the video card, I have a laptop hp dv series 6795el, windows vista 64 bit original, starts and works well if you do not use games of various types for a few hours, as apparently warms and stops working before the driver video card and after remains unusable because flickers and can not see the video, touch off and on again after it cools.

For me it is a problem because it does not work and I can not afford to buy one, it had to use my girlfriend but so is unusable, you think I did change in good faith with a desktop computer, because I needed something smaller (in factor space), beginning seemed to go well, only after you have begun to use games and online games started making defects.

I also told the person that I did return for these defects but ignored what I was saying, in short, I was literally cheated, deceived, because you feel superior and should be a technical pc ... so I was disappointed to 100%, untrustworthy person that for sure I will not set foot in my house.

Miserable ...

You have had similar disappointments?

... I am very angry.

... nothing help me with suggestion ?

Have you tried opening the computer up and cleaning all the dust from it? Also, make sure there isn't anything caught in the motors on the fans, that might make a difference. Also, download "speedfan", it's free and simply, and it will let you know the temperatures and speed of your fans; you might be able to see if a fan isn't work like it should.
