Hey guys. Im new here and I just got Halo 2 for Vista. I just installed the game and it was fine. Everything was going great. I went to change my resolution from 1024x768 to the one right above it and the game messed up. I got a blank screen and couldn't see anything but I could hear stuff. I restarted the game and the same problem. I couldnt see anything but I could hear the sound from the menu. I uninstalled it and re-installed it and still the same problem. Once the game is up and screen is blank I have to restart my computer because idk what im doing. I downloaded the updates and everything but now I dont know whats left to do and I need help.
Just incase here is my system specs...
Geforce 8800GT
E6400 Dual Core CPU @ 2.1 GHZ
320 GB HD
2 GB RAM
