Hello,
One dump file indicates AVG and Realtek NDIS driver that causing the crash.
So I suggest you to uninstall AVG then replace it with MSE.

Update this driver:
Did you use any registry cleaning program?
I think it's better not to use that kind of program unless it's urgent need.
Left over / junk registry from unused programs won't harm your Windows, but a little registry mistake/delete/corruption that made by 3rd party program will cause system instability.
