The first minidump file shows that the BSOD was caused by ndis.sys. This program is imp. for windows and is under microsoft corporation. But sometimes some other malicious software clones itself like this file. The steps to fix it are that first download the latest driver for realtek network adapter and then open the deice manager, search for realtek PCIe FE Family Controller and update it from the location where you have downloaded the update and then wait. This should solve your problem.
And then the other dump file shows that nwifi.sys(native wifi driver) is creating the problem. So i reccomend to update it. Before update you need to remove all the traces of this driver, you can use Guru 3d- Drvier Sweeper.
When it is removed then download and install the fresh copy.
I would also run SFC /scannow to verify and repair your OS files
SFC /SCANNOW Command - System File Checker
But I recommend you to install your windows again.
