Well in my tech class at school I always dl DOS games. The pc are 95 machines. Lol once I dled Nite Mare 3d, and it cept crashing. Finally it said would you like to restaurt in MS-DOS mode. The game corrupted something and ever time you turn on the PC the game would start LOL. I had a sub that day so I was like OH SHIT when I get to school I am screwed. He had to forma t the pc and I didn't get top use it for a day
