How to Uninstall a game in Origin?

Sounds frustrating for sure.  In past trouble shooting, these were suggestions in no piticular order. Some worked and most didn't.   If not, I would open a ticket.

1. Disable all anti virus and use task manager to kill any background programs not needed.

2.  Use msconfig* to stop any and all programs not essential to task from loading at start up.

3. Make sure any browser plugins, especially Java, are disabled unless required. 

4. Use configure java* to prevent from loading if necessary.

5.  As silly as this sounds, under / Control Panel\All Control Panel Items\Display, set icon size to small (this fixed issues for me in Crysis & BF3) something to do with making it impossible to select anything with the mouse in certain games with some video cards.

6.  Get drunk or laid...it wont fix the problem, but at least you will feel better so you don't kicked the dog or smash your PC... 🙂

 If all else fails, open the dreaded ticket through support.  It might take two or three days, but they usually will try and help.
