Question GPU Not Working After Windows Update

[FanMan2287]

After downloading a windows update about 2 weeks ago, when I turned my PC on the next day I had no signal to the monitor. When I changed the HDMI to the integrated one it works fine.
I have a GTX 780 GPU and a Z87X-UD5H motherboard.
It doesn't show up anywhere on my PC or BIOS, the only place it showed up was in device manager when I selected show hidden devices. It no longer shows up there however as I uninstalled it.
I tried reverting the windows update but it didn't seem to work.
I tried downloading the new windows version and doing every update possible but it didn't help.
I tried using DDU and manually downloading the drivers from nvidia but that didn't work, it comes up with an error message saying 2 things: it is not compatible with this version of windows and there is no compatible hardware found.
I don't know if my GPU stopped working or if it is some sort of software/driver issue or maybe some BIOS issue.

reset the BIOS by jumper and only connect a video cable to the 780, not the motherboard
try booting with this

I tried that and it still gave no signal when I booted with the 780 plugged in. Only worked when I plugged it back into the motherboard.

Windows update sometimes pushes out less than optimal graphics drivers.
Boot using integrated graphics.
Download the nvidia driver directly from nvidia.
Do a custom install, omitting 3d, sound, and perhaps nvidia experience.
In the bios, make the 780 the primary graphics adapter and then connect your monitor to the 780.

I can't install the drivers from nvidia as I get the error messages mentioned in the op when I try.

Since you uninstalled the device, you need to reinstall it.
Here is how:

When I go to Add advice it just keeps searching and doesn't show up anything.

Are the requisite 6/8 pin connectors fully inserted?
Consider the possibility that your graphics card has died.

 

[FanMan2287]

Yes the pins are inserted. Unfortunately I don’t have another machine to test it on. Seems strange though that I’ve never had any trouble with it and it stops working right after a windows update.
