I did a window repair on my computer at home. I was running WINXP SP2 and everything was up to date. When I did the repair alot of my drivers disappeared including my USB ports. So I uninstalled SP2 and regained full use of all Ports, printers, etc. I tried this a couple of times with the same results. Is there something I am missing. I am now running XP without any updates or SP2 and everything seems fine. Would I have to do a full reinstall to start fresh or am I missing something ????
