I recently purchased a PCI HD2400PRO ATI card, and began the setup process. Since all i had on my computer was an integrated graphics card, I didn't uninstall he drivers. I unplugged everything, inserted the card carefully, plugged everything back in and closed the case. Since I have turned it on, the monitor has just been a black screen for a few minutes now. Reading one of Newegg's reviews, apparently this has happened to a few other people. Most suggested to let it boot for about 10 minutes and then it will work. Any other suggestions?
