NVidia GPU not recognized but shows in Device Manager, everything up to/including windows reinstall hasn't helped

I have an Asus ROG G750JM that came with a GTX 860M and Windows 8.1 that I bought last spring, and which has worked great for the most part until the last few days. After installing Dying Light, I was able to play for a while without any hardware related issues. However, the game crashed, gave a ResizeBuffers failed device removed error message, and would say that "This computer does not meet the minimum requirements to run this software". After this it, nor any other game, would run with my NVidia card. Forced a few games to start up with the onboard Intel card just to try and isolate the issue to the GPU; games ran fine but obviously with unplayable FPS.

Not sure of the exact order in which I did these first few things, but think that I first upgraded my NVidia driver through the GeForce Experience from something like (approximately) 347.02 to (exactly) 347.52. This seemed to solve the issue for awhile; however, the game crashed again after awhile. Also, BSODs happened at times. At this point I hadn't noticed that other games would not run either. Then I decided to downgrade to the NVidia driver 337.88, the latest driver listed on the manufacturer's website. This seemed to work for a while as well, but also eventually crashed. It was around this point I noticed that it was an overall GPU issue, and the card was not working at all after crashing (tried rebooting of course). I decided to reinstall to factory settings, backed up my schoolwork and the drivers I would need on an external hard drive, and the problem still occurs.

Any help would be greatly, greatly appreciated. Thanks in advance.
