I just re-installed windows 7 on my acer V3-731 laptop. Afterwards the computer was missing 4 drivers. I attempted to get them by auto updating with windows(couldn't find anything) and with the Acer website(got a "Service not available" when selecting my laptop). I was able to find my wireless LAN and PCI card reader drivers via google, but I now have 2 more drivers and I don't know what I need for them(or what exactly they are lol). I will attach a photobucket image of the two drivers. Thanks in advance for any help.
