Just bought the Visiontek GeForce4 Ti 4400 vid card tonight. After installing it in my P4B266 board I was able to boot and install the drivers. But after rebooting, as soon as the Windows XP Pro startup logo finished loading, my system would just hang at a black screen. It would let me to the desktop only under vga compadible mode. Tried several diffrent Det drivers including those on the CD. Same thing. I'm thinking the card is bad at this point. I put back in my Visiontek GeForce3 Ti 200 and everything installed nomally. Did some searching here and over at asusboards.com but didn't read anybody having this type of problem. Going to return this card and try another one tommoro. But before I do I though I'd post and see if anyone has seen this type of problem before and were able to fix it somehow.
