HI

Not sure if anyone can assist, I appear to have 'lost' my NVidea graphics card on my XPS 9550, its not showing up in Devices or anywhere else for that matter.

I have tried:

1. reinstall the drivers but the NVidea install says hardware not found.
2. I have tried recovering my machine to an earlier date
3. Inspected the BIOS but can see no reference to NVidea

I am getting up a set of flashing lights indicating the CMOS batter issue but could that cause the video card to dissappear?

Driving me nuts

Thanks in advance
