Im getting this problem as well, nice to see this community is helpful for you mate. Did you do anything to fix it?
What does the Event Viewer log at the time of the error?
I used to have this problem when i set the tdr delay in the regedit as i was crashing randomly when browsing or gaming, now i did a system restore and haven't touch the regedit so it's back to normal display driver crashes again...
Also after the 16.9.1 update, i'm getting more display driver crash while gaming and even got a green flash while running 3Dmark stress test which ended up crashing. Someone help us please!
Yes I am with the OP, please someone help me. In the exact same boat here
Hi, i got the XFX Radeon RX480 Black Edition (http://xfxforce.com/en-us/products/amd-radeon-rx-400-series/rx-480-gtr-black-8gb-dd-led-rx-480p8dba6) and have the same problem.
I tried setting the TdrDelay to "8" and removing the whole raptr applications (plays.tv and raptr itself) without any success, played how to survive 2 and it crashed now and then.
Event Viewer shows two entrys:
First the same message like smoshi has posted (application has been blocked from accessing graphics hardware)
Second "Display driver amdkmdap stopped responding and has successfully recovered".
The TdrDelay to "8" registry edit I would delete, it causes more trouble than its worth.
(application has been blocked from accessing graphics hardware) - Related to the new AMD drivers I'm not 100% on the reason? From other threads one was replying to the same error message. Looks like its a 'Group Policy' error from the driver? Something's been setup there? AMD proxy server of some sort maybe?
"Display driver amdkmdap stopped responding and has successfully recovered". - Either the GPU is faulty/damaged or you need to increase the volts slightly to the GPU. Always benchmark the unit and monitor temps and such.
Hope this helps.
I formatted my system the other day, so far so good. I hope this remains the case as what you have said about faulty GPU I hope that doesn't apply to me. It cant be faulty but if its become damaged then Im screwed.. although cant imagine how it could have been damaged physically anyway ... and I haven't overclocked it to damage it that way either
I never could get a stable computer with the Gigabyte Radeon RX 460 OC 4GB. I finally returned it (after tinkering with the computer for a week) and the replacement (same make and model) has been working flawlessly. I had to do NOTHiNG in WattMan, it just works. I had very similar problems as described here. Constant graphics driver restart/recover, "xx has been blocked from accessing graphics hardware", black screen/frozen screen even a BSOD. So sent it back, got the replacement, popped it in, loaded latest Hotfix package and good to go.
