A young friend with not much money was given a beautiful laptop with XP on it, as originally sold. But it has a strange collection of problems! Maybe they're related or maybe some are well known? 1) None of the 3 USB ports work, with a flashdrive or a mouse. How do I tell if this is a software or hardware problem? (I really need a USB mouse because I hate the built-in pad.) 2) The sound doesn't work and it says there is no sound device, though there used to be! 3) When Device Manager is displayed, NO devices appear. 4) It boots maybe quicker than mine, but some things are verry slow. A virus/trojan full hard drive scan showed nothing. When I had this problem, a month after installing XP, I disabled all the services and startup programs and reinstalled them a little at a time. I found two services**, either of which slowed me down tremendously, but he doesn't have either of those. Before checking the services for him and startup programs, is there something I should do first? **Shell Hardware Detection, and Uninteruptable Power Supply. Thanks a lot.
