I recently built a new computer with windows xp home. All was fine until I installed windows SP3 or the drivers for a camera(sealife reefmaster mini). Now, almost all usb devices (external HD, casio camera, reefmaster, flash drives) cause the BSOD (0x000000FC). The only usb device that does not cause any problem is a microsoft wireless keyboard and mouse (wireless laser destop 4000). Please help.
