Title: White screen pops up right when i join server and says i crashed

Version: 1_0_3

OS: Windows 7 w/ Asus hardrive and HP desktop (if u need that)

Java Version: 7.0.100.18

Description of Problem:

I start up like normal. It gets to where u can chose multiplayer and singleplayer just fine. I click on multiplayer, then my server. Once I get into the game, 2 seconds into it, a white screen pops up with the name Minecraft above it. It says an error has occurred.

It says to possibly file a crash report and I think this is where u do it. Please help it was working fine and hour b4 I posted this so I don't kno went wrong. I didn't do anything it just all of a suden stopped and the screen came up.
