DriverGuide has changed a bit over the years.
If you can go into devices, right click on the graphics card, properties and then show the Ven & Dev numbers (they will be the four digit numbers immediately after Ven & Dev in the VERY long string of info) then I'll be able to send you an exact link for that chip.
If you need step by step help how to do this let me know and I'll do it when I get back (typing on my phone right now).
If you're truly stuck just bring it up in the morning and we'll do it whilst you wait.
Glad the disc got you most of the way there
