Freeze: Mouse does not work, blank screen, fan on, computer light on. Thank you.
Sorry about the late response.
Is the Hard Drive activity light blinking?
When the screen goes blank, does it say Signal Not detected. How would you know that the mouse doesn't work if the screen isn't on? Also, check your power settings as these conditions resemble a computer entering into S1 Sleep Mode.
Please indicate your operating system as well.
