I have a Compaq Evo D310 computer with the Microstar MS-6541 motherboard installed. My nephew gave it to me as a gift. It came with the Geforce 4mx 420 video card installed. I know my way around the bios pretty much, as to what not to touch and what's okay. I was wondering why the Micro-star VGA Controller was enabled. If you have a different video card installed shouldn't it be disabled? I have no book for the computer. As it didn't come with one and Compaq's website is no help. If anyone could send me some information on the motherboard or the computer that would be nice. Thanks. Anna
