I was trying to help a friend rid his computer of malware by reformatting the drive and installing windows xp again. The Acer Aspire 5000 laptop is his, but I used my restore disk from my HP pavilion laptop. Everything went fine, but now he is missing drivers and his wireless card isn't even recognized in the device manager! I've downloaded the drivers, but the OS doesn't even recognize that the wireless card is plugged in. I opened up the case and reseated the wireless card, but to no avail. Windows doesn't even state that new hardware was inserted. Am I missing a driver for plug and play or something? Do I need to download chipsets for the laptop? I can still access the internet via ethernet, but the wireless is shot. Any help would be GREATLY appreciated. If I have to download a chipset, how do I know which one to download?
