The only errors that i can see are in the event log, one refers to your ATI driver, the other Cyberlinks Richvideo service not starting, either could be causing your issue.
Did you use a Driver cleaner prior to updating Video card drivers !!
OK tried that and did a clean and fresh install of Catalyst 8.5 and still have the same issue. I'll try 8.7 in a bit and see if I have the problem still.
Edit:
Tried 8.7 and have the same problem still. On first boot it crashes MP when trying to play music. If I relaunch it's fine, but if I was to reboot again and try music it would crash again.
