I have a toshiba A40 laptop that is running Windows XP Home Edition 2002 with service pack 3. Apart from being very slow it has now started turning itself off. The machine is very noisy, which I assume is the fan and this seems to be running all of the time. The activity that often causes this problem is watching tv using one of the iplayers. It is now happening more often and not always when watching tv. Sometimes I have not even connected to the internet and it happens. The pc may have been running for hours before it turns itself off or it can happen after just a few minutes. Every time it has happened the noise/fan has been running at a very fast rate. There are no warning messages that come up it just turns off. Is all of this down to memory or do I have 2 problems that need to be sorted?
