I don't know where the problem started from but I installed Civilization 4 BTS on my pc it ran fine for a while but then gave me huge graphic glitches and flashing I uninstalled it and reinstalled it, updated my drivers after uninstalling and reinstalling them, ran the game, it worked fine now but ran it again a while later and it again started showing me the glitches and now my other games won't even work warcraft 3 runs but shows a blue screen same with Civ 4(original) since i unistalled BTS, I ran the wc3 map editor it runs fine but again black screen, everything else works fine, the system is A-OK but this only occurs with games, PLEASE HELP!
