Origin Crash when downloading a game

[catster1973]

I've just recently bought the command and conquer ultimate edition bundle and every time I try to download a game from that bundle my PC will start lagging then origin closes and shows my this error messages stating

Origin has encountered a serious problem and must close.

I don't know what to do to solve this problem since I cant find any solutions for a problem like this.
