Sims 3 has been released early due to piracy problems. A lot of people have reported problems with BSOD during the game. I think this could easily be fixed with a video card driver update.
I've tried this on a Dell laptop that had blue screen problems in Sims 3 and it worked. The drivers on the Dell support page were a bit old. The video adapter is an Intel GMA, so I looked up the latest drivers on intel.com and it worked. The new drivers have been heavily tested and no more BSOD!
