I have a Mac OS X Snow Leopard version and my fan keeps coming on. I have been away for a week so it has not been used and yet when I started it up the fan started straight away. Is there anything I can do? Please help! Thanks

Yes, look in Activity Monitor (Applications /Utilities /Activity Monitor.app) and see what it eating up all the %CPU. If anything is over 40%, post the name here to get advice or just kill it straight away with the red 'Quit' button.
If nothing is using up CPU resources, but the fans are going full blast, do an SMC reset. Read the instructions here:
