When I see this I test the machine with any of the Live OS CDs since I only need to test the hardware and not touch the owner's OS or files. Puppy Linux is small, fits on a CD and I don't need to do more than boot it and see if the mouse works to tell me if this is a hardware or windows issue.
My husband has an out of warranty Compaq CQ60-615DX notebook. After the last Windows 7 update, all 3 of the USB ports quit working. He cannot use his wireless mouse or external hard drive. Is this related to the update or what? Thanks for any help.
