New NVIDIA card showing two in Unknown Device Identifier!

Hi,

Recently got my new NVIDIA 780 GTX, 6 Gigs on board, DDR5 card. Was excited to get it installed. After a bit of time figuring stuff out I got it installed and booted up and of course it needed a driver so everything was quite LARGE for a little while then the screen flashed a few times and there it was.... Nice and normal looking.

Then I started running into issues. Like when I would reboot rather than just booting in I would be taken to my BIOS screen. I don't know why but I guess there is a setting there I need to adjust but don't know what it would be. I have a GIGABYTE X99-UD4 Mb. So if that gives anyone a one up as to what to suggest that would be great. I've tried rebooting a couple of times with the same result. Hangs at the boot screen, power off and power on, goes to the BIOS and then once I "Save and Exit" then it boots into my logon screen no problem.

Another issue is that when running the "Unknown Device Identifier 9.0" it's finding two instances of the video card. One is not highlighted but the other is highlighted in red. It's also still registered to my older GTX 760 so not sure how to get rid of that. I've looked all over but can't find where that older NVIDIA info is stored. Perhaps in my registry?

Thanks for the help..

Richard :confused:

In BIOS there should be a graphics setting to chose whether to use the integrated graphics or the dedicated card. It is worded differently sometimes like dynamic or static or something different. Anyway try to find whatever it is and change settings to see if it makes a difference.

After a few more reboots the drivers and card are working with the system BUT even though I've uninstalled the older drivers the old card is still showing up, highlighted in red when I run the Unknown Device Identifier prog. Any ideas of how I can get this old cob web wiped from the system??

Try this: go to control panel>device manager, find the devices (old video card) you don't want, right click on it and choose
"uninstall". Then run the "scan for devices" (under Actions at the top of device manager window) or reboot. See if that helps. You could also mark it as "disable" if you have a device that you don't want/need that keeps reinstalling (but is not working).
