A6200 adapter stopped working

Hello,

First, my system specs:

My problem:
As the title says, my adapter stopped working (after roughly 8 months of faithful services). Friday evening, I had a message from Windows (8.1), asking me to reboot to finish the installation of some updates. Upon reboot, my adapter wasn't working, but I managed to repair the connection by disabling and re-enabling the adapter in Device manager. Then I tried to install another update, it failed, I rebooted, and voilà, no more internet connection.

So, I tried uninstalling the drivers, re-install the lastest version (.35 - standalone). Still not working.
I uninstalled the driver, I used Ccleaner to clean my registry, I reinstalled the 0.26 version (standalone) of the driver, no luck.
I brought the adapter to another Windows 8.1 machine (AMD based, this one though), installed the 0.35 drivers and it worked fine on the first attempt. This machine also has all the latests Windows updates installed.

So, tried something more. Reinstalled all up-to-date drivers on my machine, still no luck. I uninstalled the Netgear drivers, then I used Revo Uninstaller Pro to reinstall them, so it could monitor the install, then used the uninstall function to help me purge the registry. Then I reinstalled the 0.35 drivers. No luck.

And then I decided it was time to be a man, admit I am baffled and cry for help ;)

If I got into the Device manager, there's yellow triangle next to my adapter and the error message when I right-click properties:
This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

{Operation Failed}
The requested operation was unsuccessful.

So far the only thing I haven't tried is to uninstall all the latests Windows Updates... I'll do it if there's no other solution, but I thought that maybe there was some cleaning utility, akin to the ones used for video card drivers, that I could use?

Thanks for the help,
