Minecraft no respond! (Only Snapshot's)

Everyday i start Minecraft(Snapshot) it loads up, works for 2 seconds and then it says: "No Respond!" you can wait aslong as you want it doesnt do anything. When you close it, it says Java has stopped working, then close this message and it says minecraft crashed. What ever, this only happens to Snapshot versions, normal Versions do work for me.
Things i did: Reinstalled Minecraft, Reinstalled Java, Updated Graphic Drivers, cleared Cashe.
Things im going to include as pictures: Picture of minecraft not responding, picture of Java not working, picture of my latest Log. Minecraft doesnt create any Crash logs, so i cant show them.
I hope you can help me
