I did attempt to run the Driver Verifier, but there were no non-Microsoft drivers listed to select.

It cannot be. You should have tried to re-run it.

It is strange that the bugcheck codes are getting changed in every occasion, and the probable cause, too.
This time it is realtek network driver.

Code:

Use !analyze -v to get detailed debugging information.

Update it from Realtek. Get the Win7 and WinServer 2008 R2 Driver. Install it by following Driver Install - Device Manager.

Then try driver verifier seriously. What you are saying about it cannot be the fact.
