Me again... having a problem with my laptop (Acer Aspire with Vista Home Basic). Without warning, while in the middle of something, it'll just shut down. No error messages, no pass go and collect £200, just off. Also seems to be quite hot underneath. Try and reboot, and shuts down again. eventually got it to restart, but because of the previous failed attempts to restart, it goes into "recovery mode" searching for errors. Not sure if the heat thing is related. wondered whether it has a built-in shut down if it gets too hot, but haven't been using it extensively. (half an hour or so at a time). I have opened the rear cover and checked the fan. It comes on when you boot up and then goes off. it does kick back in when you run any applications, so assume this is normal. any help would be appreciated. Cheers
