Graphic card driver for GL40

Hi,

I have an emachine e720 and the graphic card is a gl40.

On this Laptop I installed WIndows 8 and I have problems with the graphic card. Windows installed the standard graphic driver and I can't play anything on my Laptop.

Now I'm searching for a driver for my graphic card. On the Downloadsite I found drivers until Windows 7. For times I have heard that gives a beta of this driver.

Can anyony tell my how I find a gl40-driver for Windows 8.

Thanks,

Rob
