OK i was using the computer normally and it was running smoothly, then out of no where, the mouse started to not work. When i moved the mouse, the pointer would not move. Also the keyboard would not work too I realized that when i moved the mouse, the light for the NUM. LOCK would dimm and reappear everytime i moved the mouse. then it would completey go blank[light].. everytime i restart the pc, the same thing happens and i also put another keyboard and mouse and still it wouldnt work. Someone please help me!! and also the mouse is a PS/2 mouse and its a wired keyboard.
