Computer randomly crashing (ntoskrnl.exe, atikmdag.sys, dxgmms1.sys)

[Nordbjerg]

Hello.

I am getting really tired of my computer crashing constantly. The main concerns are: ntoskrnl.exe, atikmdag.sys and dxgmms1.sys. I have fresh installed four times, updated all of my drivers and DirectX, too. Nothing helped.

I have send my PC back to it's manufacturer 2 times, and they said it was fine. I have also run Windows Memory Diagnostics without any errors.

It happens randomly, even though what I am doing on my computer (work, games, surfing the interwebs etc.)

System specifications
AMD Phenom X6 II 1090T
AMD Radeon HD 6970
8GB DDR3 RAM (I don't know the frequency)
Windows 7 64-bit

What should I do?

Dumps attached,
Oliver.
