Please ask your question once only. The majority of the answers in the Microsoft Community come from users of Microsoft software and hardware who volunteer their time and expertise to help other. It may be some time before a question is answered, and repeatedly asking doesn't make things happen any faster.
Your particular question, however, relates to HP hardware. Such questions should be asked in the appropriate HP support forum: http://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/bd-p/TouchSmartPC
When you ask there, include the model of your HP monitor.
As a guess, it sounds as if your button is stuck. See http://h30434.www3.hp.com/t5/Desktop-Video-Display-and-Touch/HP-w2007-monitor-quot-Quick-View-quot-screen-keeps-scrolling/m-p/345830#M50893
