DirectX / D3D issue

[-Ever-]

New build, experiencing what I think is the same issue, but in two places:

Skype: webcam freezes / goes blank after 15 minutes. Does this until restart my machine.
D3D failed to create device

Diablo 3: error arises when I Tab out / background the game. Does this until I force-quit and restart the game.
D3D failed to create device.

-I have updated motherboard drivers
-I've tried different graphic card drivers
-I updated to the most recent DirectX (11) three times.
-I've run Dxdiag. Sometimes it works flawlessly, sometimes it says,"DxDiag has detected that there might be a problem accessing Direct3D the last time this was used." Then it says "DxDiag has stopped working."

So what should I do next? I can't go on like this!

Note: I did follow this guide for SSD optimization. http://www.overclock.net/t/1156654/s...-for-ssds-hdds

Hardware:
-Windows 7
-Asrock z77 mobo
-AMD 7850 gfx

Things I would try is use a different video card. Use the video card in another system.

I'll also start with a clean install of windows also. I'll usually start with older drivers first and progressively move on to the next version.

Yeah, I'm pretty frustrated with it and am close to pulling the trigger on a fresh install. I fear it happening again though.

Maybe not I had issue like this few months ago a bad update and couldn't install SP1. I did a clean install made sure it was updated to SP1 before I started installing my video drivers. It helped in that instance.
