Webcam qui plante

bonjour voilà je viens de recevoir ma web cam je veux la mettre sur jitsmi mais a chaque fois elle plante elle ne reste pas pourquoi ?

Hello, As
soon as I put a webcam on my computer, it turns off after 10 minutes. What to do please, I chat with my children on the other side of the world and it is very annoying to wait to restart the computer, they are often in cybercafe. It only does this when I put the cam on. Thanks. windows xp AlaskasWorld
