Howdy all! GPU Problem.

[Captain Fishie]

I'm trying to switch my sister's pc from an RX 480 to a GTX 780, and the thing boots, but there's no display. I had the same problem with the GTX 1050 ti I had tried to install, but the RX 480 works perfectly fine. The PC will boot up and I see white code lines at the top for a second, and then it'll either keep blinking like that the same, or just stay turned on, GPU lights and fan running, just a black screen. I've run DDUs and uninstalled anything and everything AMD, so I'm in a rut. I can't imagine it would be a mobo problem, just cause it works well with the RX, it's just not what I want. Any suggestions? I want this 780 in the machine.

Also an update, I just kinda acted like there was a display and put in the password and everything, and the rgb on the keyboard set to her setting, so I know the thing is on, I just need a display.

We’re having the same the problem I think but expect the blinking lines part if you could check my post the one for R9 290 I have installed but failed to use due to error 43.
