Hello and welcome to JustAnswer, I look forward to assisting you today. Are you using any additional video card on the Vista machine that you need to install a driver for?
That may be causing the problem. If you go to the computer manufacturers web site, you should be able to find the video driver you need. Your computer may have come with a driver install disc as well?
Hard to say. All that Windows would report is what it can find, and most likely without the proper driver it will continue to use the generic. There is a way to track the hardware and find the proper driver, but it would be much easier to do this when we can both work together. Let me know when you will be around and I will try to set aside the same time.
Okay good. Let me know what happens please.
