Some of you have already experienced problems with non-signed drivers returning error code 10 in Windows 7.
My example is Marvell Libertas 802.11g/b Wireless driver – it returned error code 10 after upgrading memory from 2GB to 4GB. I have searched for the solution several days and couldn’t find it anywhere, although I was lucky enough to fix it!
Firstly you need to download this magical tool:
Driver Signature Enforcement Overrider 1.3b
Then, download latest drivers from Marvell website ..if any.
Marvell Libertas 802.11a/b/g Wireless (MRV-8338)(drivers) worked for me.
After you download it you need to uninstall Marvell wireless card driver (tick the box to delete all the files otherwise Windows will automatically install it)
Run the Driver Signature Enforcement Overrider 1.3b and enter Test Mode
Reboot the workstation and install new drivers.
Just to be on the safe side you may sign your driver after the installation using *Sign a system file (downloaded tool)
