GTX 970M Missing from Device Manager

[Johnnyboy]

Brand new Gigabyte P35W-v4 laptop, upgraded from Windows 8.1 to Windows 10, now the dedicated GTX 970M graphics is not showing up in Device Manager (not hidden, just not there).

Tried everything:

Reset Windows 10, twice
Disabled graphics acceleration in BIOS
Updated to latest BIOS
Install various NVIDIA drivers, but fail due to there being no card detected
Ran Display Driver Uninstaller

Still no show in Device Manager.

Any ideas?

Nothing displayed under display adapters at all?

Tried everything from the proper support page? http://www.gigabyte.com/products/product-page.aspx?pid=5453#driver

Dicking about with laptops can be a risky business if you're not aware of the quirks.

Correct, only the Intel HD Graphics are showing.

Have you tried uninstalling the intel graphics via device manager?

Failing that i would do a quick install of w8 or 7 to see if its working...quickest way to test it.

Yes, uninstalled all graphics, but on reboot, only the Intel HD is detected.

I'm struggling to roll back to Windows 8. Deleted the windows.old file previously, needed the space, so that route is no longer available. Can't install 8.1 from USB/DVD, as the primary disk is formatted to GPT (not MBR) and Windows 8.1 can't proceed with the install. Can't find out how to boot from the recovery partition either. The current Windows 10 install doesn't detect the partition when I try the Repair/ Reset recovery options.

Thanks for all the posts. Kinda stuck here, any other ideas, or best to RMA?

disable secure boot from BIOS?

try any Linux live USB to see if that picks it up to rule out OS problem.

Set power options to high performance?

Managed to install Windows 8.1 on the secondary HDD, but the GTX is still a no-show. So I need to wait for Gigabyte to issue an RMA. Pity, I really like the laptop. Or do OCUK arrange the RMA?
