We may need more MiniDumps
But looking at the log, I would recomment to download the latest updated drivers for your Sound card and Video card.
Then fully uninstall your ATI video program from add/remove programs
Possible leave the sound program installed (some are ok some are not with updating)
Then after restart, update both Video and Sound drivers fully (some adjustments may need to be done as well after that - ie screen settings so forth by you)
Reply back if it helped resolve the issue.
