Hi, yes, I did clean the mouse, and it will jump to different parts of the desktop and open and close programs, the keyboard will cease functioning also, unable to write in text in any entry on the browser, so unable to go to specific sites. When I log onto a site I will be suddenly booted from the internet, IE will close and I will be disconnected from the site. Eventually the cursor will not move and the monitor will freeze up, I will be unable to even use CTRL - ALT - DEL to reboot or turn off the computer, I will have to do it manually by shutting down all power.
