You need to update it from ATHEROS drivers for Microsoft Windows (Atheros?????)

Sometimes some other products also uses the drivers provided by atheros. So the MSINFO32 file may point to the issue rightly.

The Display Driver is also failing there. Search in HP's site for any available display driver update for HP Pavilion dv7 Notebook PC (1443).

Yes, it is Atheros AR5009 802.11a/g/n WiFi Adapter.

So you need to update the driver Drivers for Atheros AR5009 and Windows 7.

The download button is at the bottom of the description. It is a zip.You need to install the downloaded athrx.sys (contained in the zip) manually. Driver Install - Device Manager

Now observe the situation. Let us know how it is going ... if there is any further BSODs, upload the dumps.
