Random BSOD after hibernate/sleep on Win 7

Just to confirm before I uninstall the old driver: the new atheros driver zip file I downloaded has no setup.exe that I can see. Will it still install?

You may have to go through some other steps to install it. After doing the steps to uninstall the driver: Driver Install - Add Hardware Wizard and follow steps 1-6 exactly. When you browse, find the directory that you had unzipped containing the drivers. Click on the appropriate drivers for Windows 7.

After trying everything I could think and all that was recommended, short of doing an OS re-install, failed to solve this problem and finally resorted to uninstalling and completely removing the Nortel VPN client. At the moment this is the longest I have gone without a BSOD or problematic startup of any sort in the year I have been using this laptop. Even though I can no longer access the intranet, it's no matter: problem solved.

Glad to see it solved, though I am sorry to see you cannot access the intranet. You may be able to find another method to do so with a little research. You are welcome to post a new thread in other parts of SevenForums (software, hardware and devices perhaps?) and see if others can give you more options.
