the drive sweeper they used may have removed some of the mb chipset drivers. with the missing chipset drivers the pci devices may not work right. if it a intel chipset mb download the newest intel chipset driver. amd has the ati chipset drivers. if it a nvidia or via you have to go to there web page for the drivers.
I think you're right, but all I can find on nvidiai's website are the graphics drivers, not the chipset drivers.
I'll try the intel ones as well, but I don't think those are causing the issuehttp://www.nvidia.com/object/win8-win7-winvista-64bit-310.90-whql-driver.html
This is all i can find, which is what won't install.
