nVidia GTX 970M not loading
Dear all,
I'm struggling with my Alienware 17 R2 and the video driver. Intead of the Nvidia driver it is loading an Intel one.
I have updated the nVidia driver to the latest version. I've disabled the Intel one ... but it's refusing to use the nVidia one and defaulting to a basic Microsoft driver instead.
The nVidia one is reporting as being installed and enabled perfectly ok. Still won't run though.
I am also running Windows 10 ... and have the nVidia driver for Win10 installed.
Any ideas?

Hi,
Make sure you are running the latest Bios version for your system. How are you able to determine that it is only using the Intel card?

Yes, some more context is required to better assess this. If you can explain the software that you're using to test which GPU is running, and what software you're trying to use the Nvidia GPU for, the techs here might be able to help you better.
For example, in general usage, I imagine that the AW17 would default to Intel Graphics to save on power. It would only switch to the Nvidia GPU when you run a graphics-intensive application, such as games and multimedia editors.

Thank you for your responses. ... Well it seems my troubles were caused by a failed HDMI cable.
To explain ... I didn't know about the switching between the Intel drvier and the nVidia driver to save power. So when I was clicking on the desktop to access display driver properties it was always just showing me the Intel settings. I couldn't get nVidia up at all. Added to this, the thing which alerted me to the problem was the fact my secondary display wasn't connecting. So I assumed (wrongly) that the nVidia card had been knocked out. I was wrong - it was the cable which had failed for some reason. After a long day of driver installs and reboots I switched the cable and hey presto!
I also was having trouble with photoshop - at some point it had defaulted to using the Intel driver rather than using hardware acceleration through the nVidia - so that made me think the nVidia driver had also been knocked out.
All is well with the world again! Thank you for your trouble in answering the original post.
Moral of the story ... always check your cables!
