Howdy. I have an asus rog g750jm bsi7n23 laptop. Up until December last year it worked just fine. It has nvidia as well as Intel graphics processors. After an update (not sure which one originally caused the issue) the display adapter disappeared from my devices window. Uninstalling and reinstalling did nothing to help the issue. Recently, the tech support folks over at wargaming suggested guru3d's display adapter wipe software. This does the trick, but it takes the better part of an hour to clean, download and reinstall the drivers for the GeForce 860m. This has to be done every time I shut down my laptop....maddening. Does anyone have any idea why this would be happening? I get the code 43 system has stopped the device error. Thanks. If you need more info let me know.
