Question No Display (sleep mode) with multiple graphics cards

[c.e.okkers13]

My computer has no display when installing 2 of the GPU I have, one is a GIGABYTE AMD Radeon R9 280X and also a Nvidia GeForce GTX 760. When I install it and put on my pc the screen stays in sleep mode does not even go to the BIOS screen, nothing happens. I have tested different monitors and cables still does the same. Only when I use my standard nvidia geforce 610 GPU then the screen goes on and it works. I've reinstall windows, updated and downgraded my bios change settings in bios as I read in the internet, nothing helps and I'm still having the problem. Also to note, I am unable to install nvidia drivers for the nvidia geforce 610 GPU, when I stall the drivers the pc restarts or windows crash.

Why are you trying to install two completely different GPUs?

I originally had the AMD Radeon R9 280X and it worked perfectly, after I updated the drivers this happened.. I tried multiple steps to fix it but nothing, thought the GPU was broken so bo
Got me a new GeForce GTX 760. Just to find out its doing the same.

Oh, I thought you meant both cards at once.

Download and run DDU in safe mode to remove all current drivers. Then install the latest version for your particular card and OS.

Hey.. I ran DDU in safe mode with the 610 GPU that is giving display.. Installed my new GTX 760, still had no display (monitor stays in sleep mode) doesn't even go till bios page. I then put the 610 GPU back and ran DDU in safe mode again this time just restarted after it had finished. When trying to install the nvidia drivers my restarted and it's now on with no display using the 610 that worked
