My friend has a Dell Dimension E310 PC. It had a bad hard drive so I put a new 320GB SATA drive in it. Loaded a fresh install of XP MCE. Loaded SP3 and all available updates. PC runs great, EXCEPT.... if I plug either of his Digital Cameras into it via USB cable the PC immediately reboots. I have tried different USB ports, different cables. One camera is Samsung, one is Sanyo. Both worked prior to new HD and OS load
