Ive got an m5500 with a d900t board and an ati x800 card. The thing turns on and shows the alienware logo and you can get into the bios, but when it gets past that the screen goes blank. wont reboot with ctrl,alt,del, have to hold pwr button. when i turn it back on sometimes the screen goes all white, sometimes all black, sometimes it posts correctly until it looks for an os again then it goes blank. the video bios is says the card is a x28 in the bios menu not sure if that is a problem. Could anyone tell me if it is the video card, mb, or what???
