ok me and my brother are both worldof war craft players, while my brother was playing wow on his computer he wanted to change the mouse. ok when we changed the mouse it wouldnt want to work, the cursor would not move, so i restarted the computer, and when it turned on it would display the big e (because it is an e machines computer) and then the screen would go blank and it would shut down and restart immediately. can anyone help me? ive already opened up my pc and cleaned it out because it was pretty dirty but it still does the same thing.
