Though i'm not a gamer i recently bought this zebronic graphic card nvidia geforce fx 5200 with 256 MB ram and lately i've been getting this screen where nothing works everytime i exit UT 2004. Its not a black screen its just a clutter of some colors and no desktop material becomes visible though the mouse works fine. I can't seem to do anything at all when i exit the game nor does pressing ctrl+alt+del work. I have to improperly shut down the computer everytime i play this game. So is there any solution out there guys, you gotta help me.....
