So my brothers laptop has a issue with it. I believe it's a driver issue but here's the odd thing it's with the nvidia drivers. His laptop is the Alienware m11x (revision 1 not 2) and what happens is it only works with the old drivers from the dell website. When we install the new drivers problems occur (picked the right drivers and stuff from nvidia driver site). Problems include: not being able to change graphics card from the intel one to the nvidia and vice versa, having bsod when using the intel card to watch videos. Any ideas how to rectify this? I did try to use the cleaner to clean it after uninstalling he drivers and then installing the new ones (even has trouble installing the new ones like it will stop Half way and say error cannot install).
