I have a Lotus p150em se notebook made by Malibal. It has a NVIDIA GTX 675M and an Intel HD 4000. The Intel card works but the NVIDIA GTX 675M drivers cause a blue screen of death whenever I try to open the NVIDIA control panel or play more graphically intense games. It was stable for awhile but when but when I had to restore, it no longer works. The drivers on the driver disk from the factory and the latest drivers from NVIDA's website both give me trouble. I noticed Malibal no longer sells the card and my warranty has run out.
