What driver version are you using?
My driver packaging version is: 15.201.1151.1008-151104a-296217E
AMD Catalyst Control Center Version: 2015.1104.1643.30033
Surprisingly it has stopped this problem without me interfering. All I did was testing the GPU using Heaven Benchmark 4.0 and underclocking/modifying clock and memory frequency using AMD Catalyst's OverDrive and Sapphire Trixx (The card is Sapphire).
OS is Windows 10.
Tell me if you need any more details.
This is my card: SAPPHIRE Technology
I tried to boot with a different hard drive that had an older built of Windows 10 and a different driver version that wouldn't have any problems. But it happened again...
I changed one of the two power cables of the card and when I rebooted, I found some black dots flickering in the POST screen (Motherboard's logo).
Edit: I also started a thread earlier on another forum and it links to other thread I started that I had some other problems suspecting PSU, not sure if it is related: Display problem: shifted display and horizontal RGB lines clear after a restart. AMD HD6850 - Graphics Cards - Graphics …
Could be faulty hardware, however the HD6xxx series has reached peak optimisation and been moved to legacy status, there will not be any further driver updates for your product. More information available here.
The latest Crimson driver for your system is 16.2.1 and is available here.
The last Catalyst driver for your system is 15.11.1 Beta and is available here.
I would recommend using DDU to sweep your system of AMD drivers, and then trying the drivers above to see if they resolve your issue.
- How do I diagnose/troubleshoot it to know it's a faulty hardware? And what components of the hardware? GPU? MB? PSU?
- How do I know which of these two drivers to install? Is there a place to check for "known issues" with any of these? Are they even different or the same?
I'll try wiping the drivers and install it again but I'm suspecting hardware.
The best way is to try it in a different system. You could also try it in a different PCI-E slot, with a different PSU, in a different Motherboard.
I would try 16.2.1 and if the same issue occurs, try 15.11.1 Beta.
