I bought the aforementioned laptop almost a year ago and it worked great up until about a week ago. The problem began after playing Dying Light for a few hours; the game would crash and give a ResizeBuffers failed - device removed error. I noticed there was an upgrade (albeit a seemingly small one, from 347.25 to 347.52) for my driver so I downloaded/installed that with GeForce Experience. This seemed to solve the issue for an hour or so until the same error occurred. I then rolled back to the manufacturer's recommended driver, which again worked for a while. I know this was a poor choice, but I reinstalled a number of drivers bouncing back and forth between them to see if one would stick. Eventually, the game would not start at all nor would any other game when trying to use the NVidia card (onboard graphics would start the game, but is obviously unplayable). I noticed that while my GTX 860M showed up in both the Device Manager and dxdiag, my NVidia applications (NVidia Control Panel, GeForce Experience) weren't recognizing the card. GF Experience says unknown instead of listing my GPU under the games tab, and the Control Panel doesn't show previews with the image settings option. Also, in dxdiag Direct3d Acceleration is "not available" for my GTX 860M (all 3 DirectX options are "enabled" for my integrated graphics card) when I assume it should be.

Now I really began to panic. I spent a ton of money on this laptop with one of the main reasons being the graphics card. As I was overdue for a fresh install and memory wipe (I try to do this 2-3 times a year anyways), I reinstalled Windows 8.1. Installed drivers in (as far as I know and has always worked for me in the past) in the correct order, and still nothing. Still hoping this is somehow a software issue. Any and all help, any minor or major thing I could try would be amazing. Need the laptop for school so taking it to a technician for even a few days is tough. I know the warranty may be an option but that is also last resort. Really enjoy playing some video games in the little spare time I have that isn't occupied by schoolwork/girlfriend/family/et cetera.

On a side note - never buying a "gaming" laptop again. If this was a desktop (and the card does turn out to be bad) I'm out a couple hundred bucks, not a whole new computer.

EDIT: Not sure if I should label this as "Seeking solutions (not a discussion)" or not so I unchecked the box. While a solution would be ideal,any discussion or advice that leads me in any direction from where I am (laptop is now a heavy, glorified netbook unless a professional can fix it)
 
Make sure that the NVIDIA card is selected to be used all the time in your options. DO NOT allow the laptop to choose what card it uses. I am almost certain this is a Optimus bug. Try it out lets us know
 
Hi spj0078,

I have this same exact problem on my asus G750 with Nvidia GTX 860M

Were you able to get it fixed?

If you had it sent back to ASUS, how long did it take for them to get it back to you?

Also, if it wasn't under warranty, how much did it cost?

Your reply will be greatly appreciated
