Answer 1

You must increase the ram in your minecraft. If it stays at a default 1, you are either using a 32 bit java on a 64 bit computer or a 32 bit on a 32 bit. Which doesnt really allow for alot of mods. Also low ram on the computer may also cause this. It can cause alot of games to crash, even non minecraft games.
