Hi Nic,
This is my first post. I own an Asus N550JV with Windows 8.1. I'm currently experiencing an error code 43 for the NVidia 750M combo'ed with Intel Integrated Graphics 4600. I can disable/enable the NVidia GPU and Windows reports it's working, however, the NVidia control panel gives the message "You are not currently using a display attached to an NVidia GPU." I've read over this post and tried many things and still have the problem. Thus far I have tried:
1) Wiped the machine and started fresh.
2) Installed both Asus certified graphics drivers for 8.1 (Intel and NVidia).
3) Installed the recent 3345 Intel driver - normal install didn't work and had to browse for the new driver
4) Installed various other NVidia drivers - currently on 331.82.
5) Attempted to install NVidia 331.93 beta drivers as you recommended, but the installer for that says I don't have NVidia hardware.
6) Checked for any video-related BIOS settings. Only one there is increasing amount of available RAM to it, which I set to the maximum (512 MB).
Is there anything you can recommend I try?
Thanks!
Tony
