Frank, can you run everest or belarq on the laptop, it might just mean you'll have to grab the drivers from the makers of the cards that are in the pc. for the wireless (hope I got the correct specs) go to
http://downloadcenter.intel.com/Deta...=2259&lang=eng that should sort out your wireless after which run MS update and it should find the drivers for the PCI and SM Bus.
Question for you have you looked properly on the Acer website as I just found your laptop with all the drivers for XP...
