No Respond after starting the game.

When I start the game, all is good, but after the game is nearl started, the loading bar stops working, and the the games says "No Respond". Then I have to close the game, then the luncher says me "Game crashed." I can use the BAC client. This bug is on every version of Minecraft, also on the 1.0.

I hope anyone can help me to fix this bug.
