AMD GPU odd behaviour

[toohuge]

All,

I just installed an AMD Firepro card (it's actually a Barco branded card, but it's built on ATI hardware).

Anyway, something really odd happened, it was working fine, all drivers installed fine, display looking great and generally all looking good. I was looking through some display options when the resolution suddenly dropped to 1280*1024 and then black screen....

Following this, the computer wouldn't even boot (win 10 pro). I put my Quadro card back in and managed to get a desktop, uninstalled all the AMD drivers etc. and then reinstalled the Nvidia drivers. Computer boots fine and operates as normal, on first boot a windows message comes up saying the AMD drivers have changed and need to be reinstalled.

I tried installed both cards... and it did manage to boot to windows. However, it looks up completely when trying to installed the AMD drivers - although I know I am playing with fire when trying to run both AMD and Nvidia GPU's.

Finally, I tried removing all the drivers and just using the AMD card, the computer won't even boot, I can't even get a bios screen.

Any idea what's happened? Has the AMD card gone pop?

Thanks
Chris

My guess is that the pc is booting up but you just cant see it.

I would try fully removing all traces of the AMD and nvidia drivers using the following tool.

Then try installing the AMD drivers from scratch.

I've tried that approach already and no change.

I am pretty sure it is not booting as although the fans etc are running, the light on my usb mouse is not illuminated. Whereas on a successful boot, it is...

Well the mouse should probably come on yes. Have you got another pc to try the card in?

It would suggest the card if all works with the nvidia card and the card is seated properly and psu cables to the card checked/replaced.

Thanks MintyScot - I contacted the seller and he has refunded me!

I think I'll try a different Quadro next time, something a little more mainstream …. it should run the monitor fine.
