Hi i bought a Nvidia GT 240 for casual gaming but i got it and the drivers keep crashing. Most of the time it recovers but sometimes it restarts my computer or freezes. It is especially frustrating because it happens so frequently. I have updated and re installed the drivers and i have cleared all the drivers and installed again. I have also contacted the company (XFX) and they had me send my card in and they sent me a new one and said there was nothing wrong with either of them but sent me a new one anyway. The new one crashes much more frequently. I called the company and they said it may be my power supply or my motherboard. They told me to take it in to a computer repair shop to see whats wrong, but I have 2 reasons why I want to avoid that option. 1) Last time i went to a computer repair shop I was very dissatisfied with the service; 2) i have a Nvidia GeForce 6150 SE integrated graphics card, and this one does not have any problems (its just cant run the games i want to play). I am posting this because i want to know whats wrong and see if i can avoid going to a repair shop. Any help with this problem will be greatly appreciated. For my other computer specs: I have an Antec 520w power supply and an AMD Athlon II 635 quad-core processor. If you need more specs just ask.
