Heat produced inside a computer system is blown away through the air vents either by natural convention or forced convention. Now, according to computer services, due to bad cooling design the system often gets over heated with a long term of usage. Every individual component of your computer generates heat as much as they work. So, how to know when your system is about to get fried!
Sudden inexplicable shutdown, blue screen and frequent memory error are some of the symptoms of an overheated computer. So, facing the problems you must consult with a tech support expert and do something to lower them immediately. As computer services indicate, other than Microsoft Windows and Mac operating systems most of the other computer motherboards come with built in temperature sensor utilities. Also third party software is available for the OS having no such utilities to monitor and regulate system temperature.
However, you should also keep the system clean as dust is one of the main causes of overheating. Also if the fan is noisy it might not be working properly. So, be careful about the peripheral issues and work them accordingly to keep your system cool and healthy.
