Hi - I have an idea, but first tell us when it started. Is it a new phenomenon, and can you pinpoint the day or event when it started. Have you looked at event viewer?
Help!! have spent days trying to resolve problems with USB ports, am running XP SP3 on an Intel Celeron mobo 1.80 Ghz with 1.24 RAM installed. Have tried most of suggestions from other posts, uninstalled USB ports, checked "hidden devices", uninstalled Adobe Photoshop Album, disabled Hub energy saving in Windows. Allto no avail....even my computer technician is stumped. There are 4 USB ports (2 front, 2 back) each port is self-powered (?) at 500m/A. There is power in the ports, but as soon as you insert a usb device, i.e clickfree back-up drive, flash drive, camera, on any of the ports the system comes to a standstill, no pointer, mouse function, key function etc. if I restart, I get the mouse and everything else going, but comp. gets really slowed down, and still won't run/recognize inserted devices (doesn't show up in MY Computer as any drive whatsoever!!! I have run out of ideas...any else have this occur and if yes what on earth is the solution. At wits end.
