When I boot up, all the BIOS seems happy, it goes through everything normally, but when it gets past the Vista loading bar, the display goes to sleep and I can't do anything about it. I am heavily under clocked, and am on the latest nVidia beta driver, 320.49 I believe. Any suggestions? I DO NOT HAVE THE VISTA DISK; THE COMPUTER WAS BOUGHT PRE-MADE THEN GIVEN TO ME. Well, it's a long story, but I DON'T HAVE THE DISK.

If your pc is a prebuilt it should have a back up image on the hd.

    If the video card has multiple outputs, make sure that it is not outputting to a port that you don't have connected to a display.  Also, try booting in SafeMode.
