Firstly it is an XP system machine which is about 10 years old. I have newer machines with Windows 8 but my XP machine is my favourite & the one I use most of the time.
Occasionally the fans within the tower have come on full speed sounding like a vacuum cleaner. I have turned off the machine & pulled it further away from the wall to allow better circulation. I have also removed the side panel & cleaned any bits of fluff on the vents. That has usually resolved the issue.
For the past three days however this has increased to about three times each evening. A day ago I left the side panel off & a few hours ago the fans still came on full speed. Before this happened I was trying to launch Word that took forever to open.
Today in London the weather is very hot & humid & so is the room where the machine is situated.
What could the problem be the hot weather or the machine itself given its age?
If it is to do with the age of the machine what is causing the fans to come on at full speed?
