How much RAM do you have on your system? Have you tried reloading the driver or the operating system?
I have 2GB DDR2.
Unfortunately reinstall didn't work neither for OS nor for driver.
I downloaded the lastest driver from intel but no chance.
We have not encountered any problems with the drivers for this graphics controller. At this point, I would recommend contacting Acer to find out if similar problems have been found in their systems.
What is the Max Ram recomended By Acer ??
