Base System Drivers

I have an acer asipre 4730z notebook it used to run vista. I have changed it to windows 7. I cant seem to find a driver for my base system. Can anyone tell me where i might find it?

thank you very much

The drivers page for your laptop is here : http://support.acer-euro.com/drivers...k/as_4730.html

Although I'm not sure which base system device you are missing drivers for. Is any functionality missing (such as a card reader?).

I would try downloading the Intel Chipset drivers for your laptop from here:

http://downloadcenter.intel.com/Default.aspx (use the Chipset identifier first, or the "Automatically identify and find drivers" tool).

If the Intel chipset software doesn't sort it, try the card reader drivers from the first link I posted.
