Minecraft Java Crash

When starting Minecraft, it works for a few seconds, and then crashes for no reason. Minecraft always worked fine on my computer. The Minecraft.exe and Minecraft.java both crash the same way, I put the crash log as an attachment to this post.

Computer specs:
OS: Windows 7 , 64 bit Build 7600
CPU: i5 Quad Core
Memory (RAM): 12GB
Java: Version 7 Update 17 (x64)

Like you can read in the changelog, I was trying to record a video with DXTory, that worked fine yesterday too, with the Minecraft 1.5 Pre-Release.
