Hello to all,
I have this problem from last two days. I have Hp computer with Windows 7 installed. When I open multiple window like Windows Live Mail, windows media player, Firefox browser or something else, all of a sudden all opened windows disappear and after some times like after 5 seconds all disappeared windows again reappear and started running. I don't know what happened to it. I don't know why open windows disappear for 5 seconds In windows 7. Please help me to fix this problem.
