I have a Q my comp keeps freeezing up every few mins where I have to restart it with the reset button, my mouse stops responding, and little triangle looking things show up above the mouse on the screen when I try to move the mouse, and every once in a while every thing on the desktop, like the icons and task bar stop responding to the mouse pointer when I move it over there, any sugggestions on what could be causing this??? would be greatly appreciated if anyone can tell me whats wrong.
