Typically this happens because the computer isn't really up to running the game. 'Minimum system requirements' are truly minimum - it will technically run on a machine with those specs - but it may not be playable. Chances are that you need either more processing power or more memory. Try exiting any programs that run in the background - updaters, chat programs (even when signed off, some are running anyway), everything you can. This will free up memory and sometimes processing power, and may get things working.
