I am having a bit of a problem here, thanks in advance to everyone who tries to help.
Okay, so I just recently had a 8800 GT crap out on me so I decided to go with two 9800 GT's as a replacement.
My motherboard is an Asus P5N-D. I only had a 450W OCZ power supply and I don't think it was quite powerful enough for the two cards because my monitors would just stop getting a signal.
So I put a 750W PSU in my computer and after this Windows would boot into the Login screen. It appeared that Windows was loading and the screen would go black right before the login screen pops up, but the screen stays back and the login screen never appears. So I booted into safe mode no problem. Removed my drivers. Took out one card, then booted up, no problem. Installed the Nvidia drivers, shut down, put in the second 9800 GT, added the bridge, then booted back up. Logged in and windows recognized the other card and asked me to reboot again. This is when windows stops booting, hanging on a black screen before the login. Only way to get past it is to take out one card, or else to login to safe mode and uninstall the drivers and undergo the same process that gets me a hang before login.
I have also updated my motherboard drivers and have the latest drivers from Nvidia.
Thanks again in advance for any help.
