the above bugcheck means the registry had an issue which may have been caused by corruption or hardware errors. This was the main dump file in the collection you sent although you also had Bugchecks blaming the USB3 drivers. This:
Windows 7 Kernel Version 7600 MP (4 procs) Free x86 compatible
Tells me your missing a critical service pack and you need to install asap:
The download you want from the list is at the very bottom:
Download Windows 7 and Windows Server 2008 R2 Service Pack 1 (KB976932) from Official Microsoft Download Center

If you have any issues installing the service pack run the readiness tool:
Download System Update Readiness Tool for Windows 7 (KB947821) [October 2014] from Official Microsoft Download Center
