If you could take a moment and do the following as well, it would help get some more minidumps if the crashes keep happening. Despite your claim to the frequency there were only 2 minidumps included the most recent from the 8th. To ensure minidumps are enabled:
Go to Start, in the Search Box type: sysdm.cpl, press Enter.
Under the Advanced tab, click on the Startup and Recovery Settings... button.
Ensure that Automatically restart is unchecked.
Under the Write Debugging Information header
Select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
Ensure that the Small Dump Directory is listed as %systemroot%\Minidump
OK your way out.
Reboot if changes have been made.
