Planet Minecraft

My Minecraft has been running fine lately untill a day after 1.3.1 came out,i tried to play minecraft when i got a Stange error that said ERROR:Could not create Java Virtual Machine. ERROR:A Fatal error has occurred. Program will now close.
Ive never gotten this error before and ive look up things to try,like going to Java 6,didnt work,Uninstalling all java,Restart computer,reinstall java didnt work,and even tried doing the Put soemthing into the Notepad and lable it minecraft.bat and run minecraft on that,still didnt work. If any of ya'll could help me,it would be much appreciated.

First of all, do you have any mods installed? Second of all what are your PC specs (Can you run minecraft at 60 FPS or more).

One of the reasons Java might not have been able to create a virtual machine is because it could not allocate enough memory to the game. Are you using a special launcher to give Minecraft more memory? Also, what the specifications of your computer?
