Well I have recieved and error along time ago before I sent my video card off that said something about drivers in a continuous loop. I don't get that anymore. Not only have I tried reinstalling drivers before, I've even reformatted many times. I did just uninstall and reinstall drivers but itstead of getting them from nvidias website I used the driver cd. Now Swat 4 seems to work fine when I alt+tab or exit out of the game. However my screen saver still freezes(i can still move mouse but I can't control+alt+del or anything) and now every time I log in and then out of a character on WoW some of my menus are messed up(if i alt+tab it and bring the game back up again the menus are no longer distorted). Im going to try reinstalling it to see if that helps. Its just like problem after problem. Any other ideas?
