Hi my computer started to freeze while in use and I could not get the arrow down to the right hand bottom corner to to turn it off so I turned it off manually. When I tried to restart the blue screen appeared with the Acer logo and written below it came up repairing disc errors this may take over an hour to complete. Well 10 hours later it was still doing the same. So I turned it off again and now when I turn it on I just have the blue screen with the Acer logo on and that is as far as I can go. Can anyone help please!!!!!!
