OVER HEATING AND SHUTING DOWN

I have been on here for the last three days and iam seeing alot of people saying there pc or laptops keeps going on and off.well not all the time but most of the time the reason for this is,over heating.check that you can hear the fan or fans are running smooth if they are not then you need to clean them up.laptops are not easy todo trust me i know,i have been working with pc and laptops for over 20 years.anyway the best way i have found to clean them is with a hoover,just put it at the side of were the fan is and turn the hoover on,its that easy.mind you some times you have to open them up depends on how dirty they are.the second reason for over heating is the processor can over heat as well,but thats for another day that you will have to open them up todo.happy cleaning.
