I live in the UK and currently run a Toshiba Satellite Pro Laptop computer, which is about 1 year old now. My computer from time to time switches itself off randomly without warning. I have thoroughly scanned my computer with Anti-virus software, anti-spyware software and run a firewall. I use a broadband internet connection. I have tried a complete system restore but still the problem persists. I now suspect that it is due to my computer overheating, since it only occurs while playing Runescape. But if so, can i alter the speed at which my fans work? Also i have been playing Runescape since September and it has only just started in the past few months. I run Windows XP Professional. Thanks for any help or tips
