Why is Windows deactivating the Driver for one of my R7 265 cards due to a "Code 43"

*I put in a support ticket almost two weeks ago & got no reply besides the "we got your ticket" form letter email*

I have tested both cards individually, in both PCI-E slots, and the cards work fine ... so it isn't hardware ... and my PSU is way over what this system needs (1kw) so it isn't power related (system built in early 2015 & has been working pretty good for a mid level gaming rig).

I actually noticed this issue back in November, but my system had been acting funny for a while and it took me a bit to even notice that the option to turn on crossfire was missing from the Radeon program. was pretty quick work after that to open up device manager and see that windows had a "Windows has stopped this device because it has reported problems. (Code 43)" error on one of the cards ... here is the kicker: rolling back to 2016 driver solved it (for a bit) and both cards jumped back on line.

I even tested updating to a couple of different newer drivers from 2017 and every time it would cause Windows to shut off one card, and then re-installing a 2016 driver fixed it. Fast forward to the other week when the latest driver pack got released and I figure "what the hell ... worst that happens is I just have to roll back to 2016 again" ... NOPE!

Now rolling back isn't even fixing the issue, neither did updating every damn driver & firmware on my system that I could find was out of date, and now I am stuck with 1 of my two perfectly good video cards shut off because of some dumb resource conflict that I can't find.

Yes I am bumping this: I want my second card working again!


Decided to bite the bullet and upgrade to Windows 10 ... same exact issue / no change.

System does not care which cards I have installed: the second something gets assigned to PCI BUS 2, it shuts that card off.

as said before: single card in either slot = no problem / both card installed = BUS 2 gets the code 43.
