I have recently tried to install a GeForce mx400 64mb PCI video card. Everything was going fine until I tried downloading the new drivers from the CD and from various websites.....none of them have worked. My problem is, after installing the new drivers and restarting my computer I get a black screen with just my mouse pointer in the middle. I currently have a Compaq Presario 5000 with ASD duron 750Mhz processor. *warning* I'm not too familiar with computer talk, so if you can offer me any advice english is appreciated
