So, I have a very crappy computer and me and my brother wanted to create a small one for me and him to play. We don't have much modding experience, we just slapped some mods together. But there is this error that keeps popping up I don't know if you deal with MMC because that's what i'm using but if you can help that would be appreciated. I'm stupid and don't know how to comprehend the easiest things but the error is:A detailed walkthrough of the error, its code path and all known details is as follows:

You seem to be missing quite a bit of the log could you post the full version. Also, why are you using MMC there is no reason you cant use the normal Minecraft client also I am not sure what the support policy is on other launchers. Make sure the next log you post is from the Minecraft launcher.

How much ram do you have in your pc

-Xms640m -Xmx3976m

This is also completely irrelevant and does not even answer his question.

He asked how much he had in his pc not how much he was launching his game with.
