Windows 10: Severe issue with Radeon HD 6670 when I have 2 screens connected

Okay guys. I tried everything to solve this issue. I read many threads about that notorious card but somehow Nothing really fitted my bill. I have reach my limit and I kindly ask for help.

Sleeping and resuming are very important to me. I do remote access andit must never fail. I'll just tell the short story. With one monitor my PC sleeps like a charm. I wake it with my keyboard or from my router with magic packet and so far so good. The problem comes when I plug my 2nd display. It is a Sony HDTV so both are at 1080p60hz. Very often, my TV is closed since I work with only 1 monitor (I use this PC to test stuff like Windows builds, etc.) Then comes the trouble. 1 out of 4 times the PC never come back from sleep. It just restart. The BSOD is not visible since it appears on my closed HDTV and I think that's the problem actually. Even if I unplug my TV, the graphics driver still consider there is 2 screens there unless I manually deactivate it (through AMD notification context menu). Then I can sleep / resume as much as I want. Problem solved.

Well... it sucks to live with this bug. Each time to activate / deactivate HDTV Or unplug / replug it... very annoying. Is there Something I missed... or maybe a more stable driver or Something like that? I tried a lot of things from the BIOS and Nothing works. Well I posted the BSOD files so if someone is kind enough then I would appreciate if you guys could check it out and tell me what I can do... The next step would be to get a new card. Thank you.

:)

 

Green screen during windows 10 upgrade

I am having issues with green screen and sometime blackscreen and I have the Radeon 6670 graphics card.

Is there a fix?

 

Cannot remote via RDP to my work desktop after update to creators edition

VisionTek Radeon HD 5570 SFF 1GB DDR3 4M VHDCI VGA (4x VGA) Graphics Card - connected to 4 monitors

Onboard Radeon HD 4250 - connected to 2 monitors

 

Well I guess I just found I can no longer do an extended desktop with my 2 screens. If I do it, then brace yourselves, the crash is coming! My computer will never wake up from sleep like 1 out of 3 times. When I duplicate my screens, then my PC become stable. Well, for now that's the lesser evil I can totally live with that, but I would prefer an extended desktop of course! Why now, and why not crashing everytime? It's so random.

I guess I am now a atikmdag.sys / Watchdog victim like many others. What I read so far is that there is as many different situations as complaints about it. I did clean installed AMD stuff with the tool then tried Crimson beta, driver only to find the same misery... :-( I'm catching up now but the issue seems very complex and there is people proposing "fixes" but it varies from forum to forum, I don't think no one has yet found the holy grail with 100 % satisfied customers below his post!

 

Thanks a bunch for the help! XD I guess maybe I can be useful anyway by reminding BSOD victims that outside routine check (drivers, PSU, etc.) Never forget to diagnose your memory (removing then put it back, memtest, timings, voltage, etc)... Manually entering the correct timings saved the day for me! Strange it worked on the last stable build but not in the beta builds. I read that slightly increase voltage can solve for some too. Each BSOD is unique, but the memory is very often involved.
