CPU:AMD 965 125W
GPU: Asus Radeon HD7770 1GD5 V2
RAM: 16GB
PSU: Seasonic Focus PX550
OS: Windows 10

Hello

I decided to make a fresh install on my system and suddendly realized that the GPU drivers cannot be installed because I get a black screen after starting setup.
Thankfully my system also has an integrated GPU.
Now Device Manager is not even showing the HD7770.
The HD7770 works fine when tested on another system, and the PSU is okay too.
All parts are working properly except the HD7770.

install motherboard chipset driver?

Update the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC, also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu, You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

As this system is quite old by this point no available chipset driver for win10 but managed to install the old one for win7/vista as i did for everyother usb3 audio etc
Tried everything at this point just installed win7 to try my luck here as this propably will work but lets see
