I have the new XFX GeForce GTX 256mb graphic card and when ever I turn on a game it plays for a while and then shuts down. The computer restarts, but the screen doesn't turn on. I was told that its the overheat of my graphic card. The part where I am really lost is that no matter if its the lowest settings or the highest settings its the same. Is there anything I can do in the settings to fix it somehow? If it is possible can you tell me step by step because I did not find it myself. Any other hints to fix this would also help a lot. Looking for help asap since a new powerful computer is a waste if the graphic card is acting stupid. >.<
