Thanks very much!
I went to those USB controllers in Device Manager and uninstalled them all. Nothing to lose. On reboot, Windows found them all and reinstalled the drivers. Now it sees my camera, usb mouse and a usb keyboard I have. It wouldnt see my old keyboard, but that Keytronics keyboard came with its own drivers so that might be it.
I think it is a good idea to reinstall totally, maybe wipe info and then reformat. I just have two little old 20gig Maxtors in this pc.
I have everything to build a better pc anyway, but want this one too.
What a great site this is, coal knowledge, heated discussions, and tech support!!
