Hello, Over the last couple of weeks I've been experiencing a problem when booting my PC. On occasions it freezes just before the Windows XP welcome screen is displayed, and it either re-boots again automatically or sometimes I have to re-boot it myself. I've had a look in the Event Viewer in Administrative Tools under Control Panel to see if anything was logged and found the following error: The device Root\LEGACY_WINIO\0000 disappeared from the system without first being prepared for removal. This would indicate that I had removed something from the system without going through the Safely Remove Hardware procedure first, but this is not the case as I always use that when removing either my USB thumb drive or my BookCourier. Does anyone have any suggestions about what I can do to get things sorted out? If the USB support on my PC is malfunctioning, can I do anything to fix it? I really don't want to have to re-install XP if I can possibly help it, especially as once the PC is booted, it works fine. Thanks for any help, Caroline. -- Outgoing mail is certified Virus Free.
