the snapman and volmgr driver indicate you may have a HDD issue. So run chkdsk /r /f to detect and fix NTFS issues. If you still have crashes, please start the Windows Explorer and go to the folder C:\Windows\Minidump. Next, copy the dmp files to your desktop, zip all dmp into 1 zip file and upload the zip file to your public Skydrive [1] folder and post a link here.
