Screen going black at "Loading Windows" screen

I've been fighting this problem now for days.

When booting my computer, I get to the loading windows splash screen. Then the screen goes black.. even though I can hear the sounds it makes at the login screen.

I first thought this was some issue of windows having my monitor listed as the #2 monitor, but I've messed about with every option I can find and no change. it was at one point, showing my bios in one port on the videocard, but then I would have to plug it into the second slot to actually see the desktop. I get the feeling that my Nvidia 8800GT may be going bad.

I was playing Aion earlier, and it kept freezing, then the trees and things would dissapear and the scenery would continue to come in and go out, at times appearing white. Finally, logged out.

Motherboard and CPU are brand new. Gpx card is about 3 years old

Any advise would be appreciated. IF I cant figure it out, ill be going to buy a Nvidia GTX 260 core 216 card tomorrow.

Ok, if I plug monitor into video card on the left, when I start the computer I can see the bios and it goes the the windows loading, then goes black. Then if I switch and plug it in on the right, it comes up.

I do not have two monitors plugged, and as far as I can tell, I dont have any options set to where it would think that either. But, if I go into the resolution settings, it does show a 1 & 2 screen option.. shouldnt it only show one and no others detected??

Have you tried getting a driver from Nvidia? I have had problems with the Windows update for Video drivers.

Yeah, I uninstalled the driver, then installed a new driver from Nvidias site. seems that some of the issue is cleared up, but still cant seem to get it to realize i only have one monitor.
