Re: Radeon HD 7850 Black screen

Jump to solution

Unfortunately neither disassembling nor a display port cable solved the problem πŸ˜•

I really think the card is broken. I noticed that I not only get a black screen when installing the driver but also the whole system freezes because I can't activate/deactivate num lock anymore for example once the screen is black.

To verify that it is hardware I would suggest you try loading a much older driver as I have seen lots of complaints similar and reports of ultra wide resolution issues. Maybe try 17.10.1 one of the older driver last know to be rock solid before a lot of the newest features were added to the drivers that fubar'd things for so many.

Good Luck!

I've installed the 17.10.1 driver but the problem persists: crash with black screen πŸ˜•

I will borrow another card to verify that this is the problem.

are you running DDU from safe mode before installing the new driver? This is extremely important.

Run OCCT from ocbase_com. It will test power supply and gpu.

It does sound like your card could be bad. Is it possible to try it on a different system to verify?
