Sims 2 graphics glitch

So I had The Sims 2 ultimate edition for some time now and I never had any problems until now, after maybe 3-ish months I got an urge to play Sims 2 and I'm greeted with this:

 
Any answer as to why this would happen, and a solution hopefully?

Is your computer a laptop ?
Does it have switchable graphics perhaps ?
In that case rightclick on the shotcut of the Sims 2 and select open with ..... graphics (Nvidia or AMD)

Oh yep, never realized that I was using the integrated graphics card instead of the Nvidia one....Thanks a lot though it did help!
