Acer laptop 8200 travelmate will not start after being off for a long period of time. I press the power button and the CPU fan starts going the screen remains black, the CPU activity light starts to blink, and then you can hear the fan just stop turning while the screen remains blank. It will do nothing after this point even though the power light remains on. I have tried removing the battery and using only the battery. No new drivers have been installed. New motherboard about a week ago but it starts up ok sometimes with no other problems. It can take upwards of 10 times turning on and off for the actual computer to start up.
