Your issue seems to be probably caused by athw8x.sys which is part of the Atheroz WiFi driver.

Updating the driver will probably solve the BSOD . Please follow the below instructions.
Uninstall current drivers.
Open Control Panel --> Programs and uninstall old drivers in the following order. If any of the drivers require a restart, please allow them to do so before proceeding to the next uninstall.

Also uninstall Networx completely. It is one of the well known blue screen and crash inducing program. In some systems, kernel mode drivers used by this program may corrupts LAN/WLAN drivers and thus leads to a blue screen issue.
Uninstall factory pre-installed softwares.
There are some factory installed apps in your system which are not really compatible with Windows 8 (they are Windows 7 ones ). Please uninstall them.
