Sims 3 on the PC it has worked before it has been uninstalled and reinstalled and it still does not work what to do

Sims 3 has been getting a lot of complaints and its because they put to much on to the software. Computers aren't as advanced as that game. The best computer in the world wouldn't be able to handle it. The game puts to much on your computer's mind. I would sell it on eBay a yard sale or maybe even keep until its worth something. Sorry....
