Laptop overheating

Hi guys, my acer d725 is overheating though I'm running my windows 7 in power saver mode. BIOS Version/Date: Phoenix Technologies LTD V1.14, 9/21/2009 I haven't cleaned it or it's vents for almost 2 years since I brought it ( I doubt its the main cause) Or something wrong with my BIOS version. Or because of application I use. And does a Overloaded hard disk add to its temp?

In laptop overheating is definate issue, may cause damage to the processor

Change your fan it should solve the problem most probably. I suggest you wait for winters to pass.

ovrloaded hard disk can nvr cause dz.i had the same prblem juz open it up nd clean the heat sink,it shud work fine.

u fan is crowded with dusty or u have to format it again..maybe dirty hardware and then try to use only harddisk for common proggrammer or games..tantalau..

Thanks for your advice guys.

get a can of compressed air an blow the vents clean, i sometimes remove my laptops keyboard to get total access to the fan & heat exchanger but if your not comfortable doing shch after consult manual DONT Attempt such ,the crap thats get inside laptops is terrible
