Well I bought the GeForce FX 5700 LE Overclocked and when I install the card and run any game or w/e other program that requires the card's power, it freezez after ten seconds or so, and the monitor turns off. Also if I play movies, after a while it turns off too. I have Direct X 9.0 and one of the latest drivers of nVidia. Now its not the card itself because I put it in a friend's computer and it worked completely fine. Now, I don't know what is the problem or what to do. I tried calling the company for tech support but they didn't help. I sent the card to the company for a replacement and they sent it back but the same problem came up. Please help me!
