i recently installed a few games on my computer (blood and duke nukem 3d) but everytime i try to play them, they freeze after a few minutes of play. i tried everything i could find but nothing works. ms-dos keeps saying the files couldn't be found, and everytime i try to close those tsr thingies the computer either freezes or (if it doesn't freeze) the game won't work because i closed all the stuff. it is incredibly aggravating i can't think of anything else to try, or maybe someone could just tell me what i'm doing wrong? any help would be extremely appreciated, thanks
