My webcam was doing good, but at some point after pressing the capture button it went like this:

Don't even know why. If someone knows, how to help me, will be very glad to here any ideas, cause i don't want to purchase new webcam right now. Really.
By the way, this is A4TECH camera, i have all drivers and programms up, my USB-port is gewd and setting are too.

What do you mean by "go away"?
The thing is when I take down the cam and everything and then start IM Magician again, it works, but until i press this freaking cap button. Then it ends again and shows this terrible noise. And it's not programms problem, i tryed different ones with the same result...
