Blank Screen: 8800gt problem or motherboard?

I recently built a new system using the Zotac 8800gt and PSU that I had in my old one. My new system is:

Intell e8400 (3.0ghz dual core)
4gb Patriot Ram
320gb hard drive
Asus P5N-D nVidia 750i motherboard
Zotac 8800gt 512mb
Raidmax 500w PSU
Windows Vista x64
Samsung T220 22" LCD monitor

Everything booted up just fine, I updated my chipsets and BIOS right away. However, once I installed my 8800gt drivers and restarted, my computer progressed normally through everything until it got to the screen where the little bar in the middle fills up a few times. After this screen, my display goes black and I receive no start up sounds. I rebooted in safe mode and I'm able to see my 8800gt in the device manager.

I think it may be a problem with my motherboard since the PSU and video card worked flawlessly in my old system. Both parts are less than 3 months old. I am able to get my display to work until I install drivers for my video card. I've tested this on 2 different monitors, 1 digital and 1 analog so I'm confident it isn't my monitor.

Additionally, I have installed all of the windows updates up to this point and I do have Service Pack 1.

Does anybody have a clue what the problem is? I've tried everything I can think of and I'm still coming up blank. Any help would be amazing.
