Webcam and the blue screen of death

--------------------------------------------------------------------------------

I have a new Dell 1710XPS running XP and it usually works fine. I recently bought a Logitech Qcam® Communicate STX and for some reason the webcam is causing me to experience a blue screen of death and critical memory dump. I get warned that there could be a hardware problem etc.

Sometimes when I plug the webcam into the pc via USB and the computer is already turned on I get the screen. Other times it'll be within 2-20min of a video conversation using skype. It is relentless though and I can't think of a possible cause. My drivers are fully up to date and the computer is otherwise in perfect working order.

Does anybody have any clue what could be causing this? Any adivce is welcome?

Thanks in advance,
Justin
