Could someone please assist me in analysing the following dumpfile. Have been getting this error anytime I use skype. Sometimes even when just using my PC for other things like watching a movie.

This was related to your Atheros driver (athwbx.sys ) I would completely remove the current driver and install the newest driver available.

When I go to device manager, it seems the Atheros driver is responsible for my bluetooth and WLAN. Shall I remove both these drivers? Also, I just did a fresh install of windows last week and these were the latest drivers available on the lenovo website for my laptop. Anywhere else I can look?

Many thanks

DUDU

Simply re-installing the newest driver from Atheros should over write both.  It is not the date that is important but rather that the current driver is corrupt

OK. Have done that last night. Will report if it happens again. Thanks for your help.
