I've re-installed the drivers of my graphic card and the soundblaster, they all came fresh from the internet. I re-installed DirectX11 (redist), wich I also downloaded from the internet. I disconnected everything from the PSU that was not essential (DVD drive, extra fans and stuff) But this did not have any influence on the problems. Just before the black-out, I get a grinding/chirping noise from the computer. This comes from the PSU I think. When I press the ESC key quickly, the blackout is postponed and the fan of the CPU is going wild. With the free program "MSI afterburner" I can monitor the GPU usage and temp. from withint Il-2 COD. It seems that COD uses the HD6870 GPU for 80 to 100% and the temp is always anywhere around 65 to 70 degrees C. No abnormal spiking in FPS, GPU usage are temperature is observed, prior to the blackout.
