|If you had no graphics card at all, you would not be able to see anything except a black screen.|
The error may actually be saying you don't have a compatible or supported graphics card to play SIMS 3. In which case you need to install a more powerful graphics card. Resetting your PC back to it's factory settings will not make any difference at all if your existing graphics card is not compatible with the game.
Read the error message carefully before posting.
