I just got a new Video card to play World of Warcraft, a ATI Radeon 9250 128m video card. I installed it did the drivers from the disk it came with and was like ok this is gonna be great. Well i start up the game and the graphic have improved a lot and i play for about 2 minutes and my computer screen go black and it reboots and im like wtf. The time varied for different times i did it but never did it fail to reboot the comp after no more than 5 minutes of play. Its not over heating, there are no drivers that i have found. Does any one know what the problem could be or where i could download what i need to solve the problem? And also i downloaded DirectX9.0c but im not sure where i need to install it... plz help
