Hello kemical,

It just happened again, but I had no problem since this weekend.
But this time I had the verifier running!
I did as you told me and grabbed the dumps with W7F Diagnostic Tool.

Hopefully, we'll be able to find out what's wrong this time.

all dump files were the same as the above. Unfortunately nothing was generated from the driver verifier and I would ask you turn this off especially if it's been running longer than 24hrs.

Try turning off hardware acceleration via the Flash application. This guide will help, look under 'Solve video playback issues:
Flash Player video playback issues

Test again and post the results..
