I believe this is a driver for Atheros Wireless USB Network Adapter

Hope this helps

Before you part with cash have you tried to find driver properly

When updating drivers dont click update in device manager, check exact model you got installed then visit manufacturers website and get the latest

If your not sure fill in your system specs in UserCP https://www.sevenforums.com/usercp.php and we can find it for you

Only know what drivers you had at the time of the original dump, and more BSODs and post them and we will have a look

Vista drivers here: Aztech Product Downloads (NO Win7 drivers)

Download the above drivers
Uninstall the drivers currently on your system
Follow these steps to install Vista drivers on your Win7 system:

Compatibilty Mode Driver Installation:
1 - Download the latest driver from the manufacturer's website.
2 - Uninstall the current drivers using the Control Panel...Programs and features...Uninstall a program applet. Then verify that the driver/device has been removed in Device Manager
3 - Right click on freshly downloaded driver installation file and select "Properties"
4 - Select the Compatibility tab - and do the following:
- Click on the "Change settings for all users" button
- Click on the box to select "Run this program in compatibility mode for" and then select Windows Vista Service Pack 1
- Click on the box to select "Run as administrator"
- Click on OK to exit all the dialogs
5 - Right click on the driver installation file and select "Run as administrator"
6 - Let it install and see if that stops the BSOD's.

If this still doesn't fix the issue, then it's time to purchase a Win7 compatible wireless adapter. I'd recommend a card that plugs inside the PC over a USB adapter - they're much less troublesome.

Heres the best driver i could find its 2008 and has whql cert for vista so should be ok for 7, just install as per usasma post above
