I had a MSI NX6600 GT video card and tried everything. I got the latest drivers and latest Direct X 9.0c. The Direct 3D worked with the old drivers, but locked up with the latest nVidea driver. These games(Age III, Star Wars Empire at War, and Warcraft III) are the only games I play and have for some time. I have know idea when the problem started, for it has been more then a couple months since I tried to play. I thought it must be the video card gone bad? I got my brand new PNY 6600 GT with 128mb DDR3 ram. I have the EXACT same problem. So the cards are ok but something is stopping these games from working and Direct X will not work with the latest nVidea drivers? To give you the rest of my system info: Windows XP Service Pack 2 with all the latest updates, AMD Athlon XP 3000+ 2.17GHz, 1 GB of Dual Channel RAM, and an ASUS A7N8X-E Deluxe.
