Hello 
Please bear with me as I am new to all this!
I have a Toshiba Laptop model no: M40X-189 of which I have upgraded from Windows xp to Windows 7 32bit Service pack 1 I also added extra 1.00 GB of memory.
I am not sure if I need any more info here for you to help me. Windows can't seem to find a driver for the video controller, and then states Hardware changes may have not been detected. I have tried Windows compatibility site and it brought me here.
Please can you help?
Many thanks in advance, and would you state in simple terms please.
Warmest Regards
Celina
