I was attempting to use DDU to fix some driver issues with an RX 570 so after trying all the other option and them not helping i went for the option named,
"Remove the driver/filter AMDKMPFD (A backup is recommended for the AMD chipset)"
and then after putting my gpu back in since i was using my cpus graphics nothing happened, the fans didnt spin at all and the bios reverted to my cpu graphics. Its not visible in device manager or when installing drivers, did it remove a pci driver of some sort?
If you are curious on what the original issue with the card was there was driver timeouts, black screens, not even giving a display signal upon startup, all the things you want to see when getting a nice graphics card.
Edit: I thought where DDU said "the amd chipset" was the chipset software that can be downloaded from their website so i assumed it could be reinstalled in case something like this happened
