Every time that I use my web cam my image will freeze after maybe 10 minutes and my mouse will stop working. This happens when I am in Yahoo chat, skype or any other chat service that I can use my web cam. I have tested my USB ports with the testing stuff that is on my computer from the system information and it states that there is nothing wrong with my USB ports. I can not figure it out. I know it is not the web cam because I replaced my last one due to this problem. My web cam works fine as long as I am not in any type of chat environment. But I would really like to fix it so that my wife and kids can see me for longer periods. When it does mess up, I have to reboot my system in order for it to work properly again. But as soon as I turn on my web cam again in the chat it does it all over again.
