driver and update problem with windows 7
I've had my computer since last April. it has Windows 7 home premium sp1. the problem started about 6 months ago. whenever i plug in any new usb device, it fails to install any drivers. hardware installed before this started still works perfectly, only new stuff won't work. and the attached picture is what it looks like when i open windows update. both problems started around the same time, so i assume its the same problem, and i am just completely out of ideas as to what it could be. any help is greatly appreciated.
