I need some help...

[Preeve]

Ok, so I boot up Doom, it works fine and dandy, but randomly the movement stops working on a random key I press and I can't do anything (For example, the key may stop working while i'm turning left and then the character will infinitely rotate left). When I press the Windows key and return to the game, the colours are screwed up and the game works for a few seconds before stopping again, or the game just crashes. Please help!

Try a source port.

Gzdoom is a good one for singleplayer, zandronum is also good for multiplayer, and odamex is another i've heard tons about, but never tried.
