go to your device manager to see if you need to update drivers and whatnot. right click my computer >> properties >> device manager. find imaging devices and click on the + sign, and your webcam should be there. right click that >> properties.
it SHOULD say "This device is working properly." but in your case, it probably doesn't. click on driver and update drivers. if that still doesn't fix your problem, i recommend calling up HP tech support.
edit: ok i just read your other post. i guess my response isn't completely useless though cause you could check on it this way next time it malfunctions.
