BSOD When Connected to the Internet

I'll have another look at the files as soon as I get home.

I need some more information.

Please fill in your system specs

Please follow this tutorial and download the tool. The tool will give you detailed information about your system specs, please fill in your system specs more completely including PSU, cooling and other used stuff like mouse, keyboard, monitor, case, etc.
The PSU, cooling and other stuff are NOT mentioned in the tool.

In the left corner below in your post you find 'My System Specs'. After clicking it you can find a link a little below that says 'Update your System Spec', click on this link to get to the page where you can fill in your system specs.

Please follow post #16 again.

The latest dump with Driver Verifier enabled (but not triggered by Driver Verifier) indicates a problem with athurx.sys.

Code:

BugCheck 1000007E, {ffffffff80000003, fffff802deff3330, ffffc48cf7884038, ffffc48cf7883880}
*** WARNING: Unable to verify timestamp for athurx.sys
*** ERROR: Module load completed but symbols could not be loaded for athurx.sys
Probably caused by : athurx.sys ( athurx+964f )

Driver Description: Atheros AR9271 Wireless Network Adapter

Atheros driver also written for - TP-LINK 150Mbps Wireless Lite N Adapter

Driver Update Site: Official site: http://www.qualcomm.com/drivers

The driver you have installed is old, dated Wed Apr 20 06:07:45 2011. See if you can find a newer driver to use.

Also try updating the driver:

I tried to update the driver choosing the Browse My Computer for Driver Software / Let me pick a list of device drivers. It showed three options: Realtek driver, Microsoft driver and Atheros driver. Tried each one, as soon as I chose the ATHEROS driver the wireless lan icon appeared and everything started working!

From the 'system thread exception not handled', the driver contains a breakpoint which no software should ever have when released.
