After many many hours of searching forums for solutions I have been unable to find a solution to my problem - so I decided to open a topic of my own and hope someone can help me with my problem specifically.
My problem is similar to this
topic, although the solutions posted there aren't working for me. In short: I have been experiencing random but frequent BSODs (16 and counting) with the message 'driver power state overload' being displayed.
In my quest for a solution I wanted to upgrade my drivers, when I noticed my Nvidia Geforce 650M graphics card seems to have disappeared. When I try to install the latest driver from Nvidia's website I get the error 'graphics driver could not find compatible graphics hardware'. Attempting to open the Nvidia control panel gives me the message 'An Nvidia graphics card was not detected on your system' and I cannot find the card listed in the device manager (only the intel HD graphics family is listed under display adapters)... To be clear: I'm quite sure my laptop SHOULD have this card, it's just not detecting it for some reason.
Since the symptoms of my problem are exactly the same as described in the topic linked above, I have tried to follow the solution described by Arc. Installed Driver Fusion, started in in safe mode and tried to delete Nvidia drivers - but nothing seemed to be listed here. I still clicked delete but not sure if this actually did something or not.
