Thanks for the help guys...
I ended up using the 179.48 BETA
and now my graphics card is recognized and no more errors.
I did however try and use laptopvideo2go
to download the synaptics drivers for the touch pad but still no luck with the scrolling.
If anyone knows how to get the scroll feature to work on a touchpad (dell inspiron 1720) could you please let me know. Also, would like to know how to get Aero Peek to work...the option in the taskbar properties is greyed out.
