I have a Sony Vaio Laptop PCG-GRT 160.  It's ALMOST 2 years old.  Nothing wrong with the performance but the laptop shuts off by itself after being on for a little while or if I am running programs that use a lot of power...such as playing music, playing movies, or using P2P software, even using powerpoint.  The computer is very loud...sounds like a jet airplane engine...which makes me think the fans and cooling SYSTEM have something to do with it.  I have mentioned this PROBLEM to many computer repair centers, but they all have no idea what could be wrong.  It is definately a physical problem but I can't get any ideas of what could be wrong.  I just hope maybe someone has had this same problem and can tell me what to do.  It's quite frustrating when I'm working on something and my computer just shuts down out of nowhere.  I have to wait another 3 or so hours for it to cool down just so it will work for 15 or so minutes when I turn it on.  Please, anyone, help me with this.  Your words are greatly appreciated.You know what this sounds like... Your fans are making that sound becuase they are all "cloged" with dust... And they came on becuase your computer is running a large program, and it needs to cool down the computer... However, becuase it can't cool the computer down, the computer overheats, and "triggers off" the security device telling the computer that it is too hot, thus making your computer SHUT itself down... Also, waiting for 10-15 minutes is becuase it is natually cooling off... You need to get that fan checked... TAKE the laptop to a computer store for a look...
