upgrade video driver?

i play an MMO, FLYFF, and theres a glitch i keep having where everything loses its tetures, and on theyre suport forums theyre saying that my graphics driver is way out of date. i tried manually updading my driver thru the monitor properties but it couldnt find anything thru windows update, so who do i update my graphics driver?

 

Go to your acer support driver download center. After identifing your netbook download the VGA driver. Save it where you can find it easily. Then uninstall the Intel Graphics Media Accelerator Driver. Your System will reboot.
Then install the VGA driver. At least that's what I had to do for my AOA 150-1777. Hope this helps
