Based on your description, it seems to be a compatibility issue between the components you have. I would like to recommend the following:
- Clear CMOS by removing all components and taking the battery out for about 20-30 minutes.
- Reconnect all components and install the latest BIOS update.
- I recommend you checking for a Firmware update for your video card.
The board model you have is a 4 series board and it is End Of Interactive Support by now so it is hard to say that a new bios update will be released for this unit.
I have the EXACT same problem with my Intel DP55WB and R9 280x. Is your GPU a Gigabyte by any chance?
My system keeps hanging at 5A with the 280x. My older 6950 works just fine. I tried all of the above mentioned steps and it didn't help. Clearing CMOS and updating the Bios didn't do jack. As far as updating the card's firmware goes, it's already running on the latest one and there isn't a newer one available for download.
So yeah, not sure what to do now, pretty stuck. I'll try downgrading the BIOS to an older version to see if that helps. Otherwise, I think I'll just have to return the card.
I am afraid to say that this seems to be compatibility issue.
It would seem so. I never got my gigabyte GPU to work so I traded it in for an MSI r9 280x Gaming. That card works just fine. It seems the issue in general is with the new Gigabyte AMD cards and older Intel Motherboards. Don't think there's any way around it other than trying out a different brand.
It is too bad to hear that. From our side what we can recommend is updating the bios or testing a firmware update for the video card.
I have the same problem but with the DB55WB and msi r9 270x gaming edition, any suggestions?
Please check troubleshooting steps above.
