Hi to all gamers, I have recently upgraded my computer and I am facing some problems while playing certain games. The current configuration of the computer is Intel Quad core processor @3ghz with 2gb RAM and has a Nvidia 8900GT graphic card. The operating system on the computer is Windows 7. On this computer I have installed Need for speed underground 2 but the game is not working. When the game is started, the main menu of the game is displayed and then the game quits on its own. So I want to know why Need for speed underground 2 is not working on Windows 7 and if anybody can suggest any solutions then it would be great. Thanks.
