Given that it's a built in Windows driver it may just be that it's incompatible with the hardware at the current point in time. I've dug around the dump but can't get find anything deeper on that particular driver.
Your ATI driver has also been flagged however.

Try rolling back to an earlier version for now to check stability. Download the 13.9 driver from here then use AMD Uninstall Utility to remove all traces of your current driver, CCC etc. Reboot and install the 13.9 driver.

Note
When installing choose 'Advanced' or 'Custom' (whichever option is available, just not Express) and uncheck everything except the video driver.
