Having exclamation marks or other special characters in your Windows username can break Java, which in turn breaks Minecraft. The only way to fix this issue is to create a new Windows account without any special characters (only A-Z and 0-9).
See http://hopper.minecraft.net/help/special-characters/ for more information on working around this problem.

Thank you tails My Name in windows is Yoshi!
