Hmmm....have you tried going to your computer's
website to find the latest driver? Sometimes, computer manufacturers "modify" the driver specifically for your system.
Try this also:
Go to My Computer
, right click
it and select Properties
. Then click on the Hardware
tab and select device manager. Click the plus sign under Display Adaptors
to see if you have any 3rd party video card installed. If you do, then you should NOT
use the Intel Graphics controller but rather the driver for the actual card you have in your system.
If you're not sure, I would call your ACER technical support and obtain help there.
Let me know.
