Your hardware description is inadequate for me to help you.
Please provide the motherboard/computer brand and model along with the hardware id string. eg: open device manager, find and double-click the network adapter you need a driver for, click the "Details" tab, select "hardware id" and give me the string that begins "with PCI\VEN", (top/first line of text only).
You also need to say whether this machine is a notebook or desktop pc.
