It seem that all people with Nvidia-Gforce 5XXM have problem with it. either 540M 550M and etc 500M series.

My laptop can turn off Nvidia card and still play with CPU alone, so I do that and now it work all okay. no longer any problem except that the graphic look suck without GPU help.

Is any of the SE technical team looking at this thread? so far with all the problem so many people report, you should realise that you have problem with 500M series Could you somehow work to fix it?

Please give some respond to our question, SE.
