OK all of a sudden my system has cracked the wobblies with me. I plug in my partners camera (kodak C310) or I print from my Canon IP3000 and my computer shuts off. It has never done this before and has just started doing this out of the blue. Tried a virus and spyware scan, nothing Tried a format, nothing Rest the BIOS, nothing Updated drivers (both printer and system), nothing Updated BIOS, nothing I plug in the card from the camera into a card reader and no problem. It just will not accept the camera plugged into it and will not print. The printer can be plugged in and turned on no problems just won't print, shuts down the system. Any ideas other than faulty mainboard :(

Does it matter what USB port - front, back?

It might be overloading the 5 volt USB line. Purchasing a powered hub and connecting one or both of them to it might fix the problem.

1-any error messages at all? 2-Have you tried uninstalling your usb hubs in device manager, then rebooting and let XP re-install the drivers? Sounds like something went corrupt. Some HELP in posting on Cnet plus free progs and instructions Glad to Help!

Does not matter what port No error messages tried uninstalling USB etc no change Will try plugging them into a powered hub and see what happens Not using a powered hub I can plug in a Flash key directly into the USB port no problems, Camera shuts down system, printer shut down system when starting to print.
