Let us know how it goes after and/or post a new crash dump if necessary.
You would also do well by checking under network section of the device manager to find out which exact Realtek lan you have. Then search the following link for an updated driver to install to replace this:

Yes, all the dumps have involved cdd.dll. That's a Microsoft driver that blends DirectX and Windows GDI together, called Canonical Display Driver. My approach so far has been to take care of other potential problems to possibly alleviate this one for you but obviously it has not worked out yet.
Cdd.dll is a Windows 7 RTM driver. There have been vulnerabilities found in the x64 version and patched by Microsoft I believe (or they are working on it.) For this reason, it can only be helpful to make sure your Windows Update is all up to date.
The next step is to download, install, run and then update the definitions for Malwarebytes. After, let it scan the machine.
There have been others with this problem and this next step did not help them but it is something that must be tried. It is a system file integrity and repair check for all Windows files. If there is corruption in cdd.dll, it will fix it. Open an elevated command prompt. Copy and paste the following command then hit enter:
