`I just installed a new power supply, more memory, and an evga 8800 GT graphics card. Whenever i try to install the drivers, my cd/Dvd wont recognize it(recognizes others however) and when it does recognize it, it says not responding when i try to install the drivers. Another thing it says when i try installing the drivers is its not windows xp logo approved and i should contact evga for the proper logo approved drivers. Does anyone know where i can install evga's drivers? Also my computer is moving kind of slow.The screen flickers when i scroll down when im on a site. Is this because i dont have any graphics card drivers installed(i did notice it going slow when i unistalled my ati drivers before i start working on the inside of my computer).
