Precision M6700 black screen - GPU driver problem?

I've been having problems with my Precision M6700 lately.

On Win7, after turning the laptop back on, the computer would start but the screen wouldn't show anything. On Win10, the screen turned black in the middle of working.

It seems like the Nvidia Quadro K3000M is involved here, because after using an external VGA monitor, the GPU isn't display in the Device Manager with only Intel's integrated GPU visible. The computer worked for a while after uninstalling and reinstalling Nvidia GPU drivers

Does this have something to do with Windows updating the wrong video drivers or could this be a hardware issue. 

Intel Core i7-3720QM 2.60GHz

NVIDIA Quadro K3000M
Problem occurred on both Win7 and Win10
