I have a sony VGN-FW36GJ laptop pre-installed with vista home premium 64 bit which is now upgraded to windows 7 ultimate 64 bit.
Before doing clean install I checked sony.com for updated support and drivers download. Apparently, after complete installation everything seems alright except 'Base system Device' error.
Am unable to fix it though it's not causing any malfunction but error mark is shown in device manager.
Please help if you have any idea
