Phase One 1394 Camera Driver

Hi,

Has anyone had problems with Windows XP locking up even when C1 SE isn't running? My computer locks up (mouse and keyboard don't respond) 2 or 3 times a day and I have to reboot. When I check the Event Viewer I see the following message.

The Phase One 1394 Camera Driver service failed to start due
to the following error:
The system cannot find the file specified.

Does anyone know why the service is trying to start if C1 isn't even running?

Thanks,

David
