I open a window and start typing, after a minute or so, the pc, the window border changes color and th mouse cursor disappears . If I try to type when this happens, the pc starts making sounds ...To get back have to bring the mouse cursor to the last position and do click, after this the sstem comes back to normal..The PC makes this event every 30 to 45 seconds........!
It happens to when open any window and wait....after a period of time the border color changes and freezes...Have to wake it up with a mouse click........???????
I didn't find the right solution from the Internet.
