In all honesty, your error would have been better given to members of Mojang, but it sounds like your Java enviroment may need updating. Try updating the version, or uninstalling and reinstalling Java. Also try to get the version of Java for your computer, x86 for a 32 bit OS, and x64 for a 64 bit OS.

If the problem persists, contact Mojang Support.

I have the newest version of java.

mason, there is a way of running minecraft with less memory where you have to make a custom .bat file to run minecraft, if it's not memory but graphics card related right click go to properties, advanced tab, troubleshoot, change the slider to the 3rd notch and it will make it so that minecraft will run.
