Problems after installing new GPU

[Caleidus]

Hi everyone: I installed a new GTX 1060 a couple of days ago, everything went fine, the card works under load (tried with Warhammer Total war and Arkham Knight, played some hours, never went over 60° temp). I then got two blue screens of death, both while I wasn't in front of the machine. Both times my computer could not connect to internet (connected trough ethernet) and I had to disinstall the network card drivers and restart the PC to make it work the first time, reboot the bios the second time. I then was disconnected randomly, some hours after the second incident, but unplugging and replugging the ethernet was enough. I don't know if the two problems (bluescreen and network card) are related, probably not.

Here's the log of the last bluescreen:
