Using 3 GB out of 4 is pushing it, you'd be safer going with 2 GB. The OS likes to reserve roughly 1 for itself, and other programs that are running need some too.

Try deleting and redownloading everything to do with FTB and try again. That includes the install folder (file path found on the options tab), %appdata%/ftblauncher and the launcher file as well.
Back up your saves and other stuff before doing this
