Alright so recently I purchased a NVIDIA GeFORCE 8500GT to replace my ATI Radeon x300 and I have encountered a problem and have no idea how to fix it, seeing as how I am no computer wiz I decided to post here hoping for some answers . Well when I first installed my NVIDA card it was working fine until I downloaded the drivers and was required to restart the computer. Upon restart, after the Windows XP loading screen everything was black. When I remove this card and install my ATI card, everything works perfectly. THanks for taking the time to read this over and I'm looking forward to hearing any responses that would be of ANY help.
