I replaced my old socket A motherboard and got a pentium D and some ddr2. I'm using the same ati radeon 9600xt and the same hard drive and everything works fine until I try loading up a game. I tryed reinstalling the drivers and reinstalling the games and the same thing happens. I open up warcraft III and the opening video plays through then the menu screen never comes up. Help please I don't know what to do. Also my power supply is only 280watts. Could that have anything to do with the problem?
