I have an Averatec 22″ AIO that came with an Nvida 8500M video card that stopped working. Averatec told me they can’t get any more new cards so I had to find a used one online. The make/model and all the numbers on the card match identically to the original one from the system. After installing it it didn’t work and Averatec said I need to update my firmware. Where can I get this firmware I need to make this card work?
