Many thank's for the advice, i will get it to the shop when i get the chance.
One thing that i have also noticed is that the Laptop only decides to get hot after i have plugged in the power pack. Sometimes it will run for hours with no problems and the problems start once you start using various programmes and applications.
Toshiba have also got some power saving options , is it worth altering these.
For example the cpu processing speed is on it's highest setting number 4, this can be turned down.
Cooling method is on maximum performance.
I also usually use the laptop with the power supply plugged in, what power options should i use for effective running Full power, high power, normal, dvd presentation, long life, would altering any of these help, thank's again.
