Thanks for the information. I will try download speed fan and see how that goes.
With the age of the laptop now about 4 or 5 years old, its really not worth spending money letting an IT guy have a look at it. Its a really nice laptop that has been well taken care of and would love to use it for a bit longer.
I don't have the luxury of saying my 3 year old laptop is fully depreciated and now I can just replace with a new one.
I will post any results from the speed fan, hopefully its easy enough to work with.
