   Check the device ID for the unknown device in device manager to make sure it's
actually the GPU. If you don't know how there is a video here. If it is in fact the GPU
then all I can suggest is trying to download and install older drivers going back
until you find one that works. 

I would suggest manually installing the driver but with GPUs I find that very often
causes system freezes and a failure to load the OS so I wouldn't recommend it.

If you have not already tried, remove the GPU from the system and clean the contacts etc.
I am pretty sure it won't make a difference but it's worth a shot. If possible
try it in the second PCIe slot on your riser. 

Failing all that, go ahead and open a ticket.

Good luck, I have my fingers crossed for you

	Cool, thats super good info. The Device ID is: PCI\\VEN149D&DEV_0102&SUBSYS_000149D&REV_01... Vendor = 149D Developer = 0102 This is the same as the information/ ID referenced in all the docs that I have been reading and trying to download for the past days, so I'm pretty certain that it has to be NVidia.. I'll try to manually update/ install the driver tonight and if that does not work, then I'll create a ticket tomorrow with the support team. Again, I cant thank you enough for your support...
