Gateway e series drivers

what is the model and manufacture date? You can almost always find the drivers by model, serial number, manufacture date on the gateway support website.
You can also find drivers by the motherboard model number, for example, on the Intel motherboard support website. Open the computer and find the motherboard number.

If you want to find out the motherboard model, download CPUZ, and check the mainboard tab.

I agree with soundguruman though. First check the Gateway download section for your PC model.
