Dolphin eventually 'stops working' on any game

[PHIJKCHUSnivy]

For some reason any game, rather it be Smash Bros. Melee for GC or one of the Wii mario karts, will always eventually end up with dolphin crashing and windows giving a 'stopped working' message.
I can run games quite well without any issues other than this, so I think it might have to do with something else.
I made an account specifically to ask about this, so im wondering what I can do to prevent this.
