Black screen at login

Junpaku · April 27, 2015

I was watching a video last night on my pc using mpc-be media player. All of a sudden my screen started to flicker and my pc shutdown. I tried to start the pc but i kept getting the message on my monitor that I must set the input timing to 1920 x 1080p @ 60fps. I dont remember which driver version i had for my display. What ive done so far is remove the graphics card and used the onboard and plugged my dvi in so that i can get into safe mode and sweeped and uninstalled my display driver so that i can reinstall the latest one from AMDs website. Installed the newest driver. Then i reinstalled and booted normally with my graphics card using the dvi (and later the displayport and hdmi) and once i reach the login screen its all black and there is no cursor. However when i boot in safe mode with my graphics card and dvi i can login. Ive also tried resetting my monitor to factory defaults, installed the gpu on another pc and installed older version of the display driver down to 13.12 from the latest and nothing works. I can boot normally with using dvi on my gpu if i have the amd drivers uninstalled. Ive also tried reinstalling windows 7 and nada.

My specs:

Xfx 7870

i7 3770k

Ga b75m d3h

2 x 4gb

Dell U2211h

Boot intel 530 180gb ssd

Os win 7 ultimate x64

Thanks

You have a problem caused by multiple monitors. I also had that once but i don't remember exactly how i solved it.

Connect as many monitors as you connected before idealy connect them all the same way they were connected before same ports (DVI or whatever).

I think in my case I had my second monitor unplugged, for some reason, but Windows showed the login screen on that monitor even though it wasn't connected and gave me a blackscreen on my other monitor.

I think you get my point. Try to connect everything as it was before. Also in my case it was a Windows thing but i am and NVIDIA guy so i won't promise anything for AMD users. Just try.

I had a dvi to my dell monitor and an hdmi to a tv. When i try to boot with those 2 displays connected with the amd driver installed i get the message on my monitor.
