Laptop turning off when fan is spinning hard

acer-aspirelaptopoverheating

My laptop seems to have reach its lifespan. Its an Acer laptop so I guess that's normal. But I'd like to hear your opinions about this.

My laptop is only 2 years old. I haven't heard the fan spinning like crazy not until these past 5 months.

What I did:

  • Hoping that its just the applications that I have installed that's consume the life of my laptop from the background. I used PC Decrapifier to uninstall some of the things that I don't need.
  • Reformatted my computer but only the primary partition since my files are on the second partition.
  • Bought a cooling pad.

None of these works.

I noticed the fan spins so hard when:

  • I have a lot of browser tabs open.
  • Full screen mode a flash video that I'm viewing online.
  • Using VLC to watch encoded videos. There's this thing called minicoder http://sourceforge.net/projects/minicoder/ to reduce the size of videos without affecting much of the quality. I'm suspecting that it needs additional software(to make life easier for the hardware) even though the video is working fine in VLC. VLC consumes about 300,000K and above(as seen from task manager) while watching videos (.mkv).

The problem:

  • Laptop suddenly turns off when the fan spins like crazy for about 20 minutes. I'm always checking to see if its already too hot(using my fingers to feel the side of the laptop) but its not so I continued watching and then poof! computer turns off.

  • Laptop won't turn on immediately when I turn it on after it turning off by itself. The light for the power goes on but its turns off immediately. I have to wait for about 10-20 seconds before it boots up without problems.

So how do I go about this? Is this just normal for Acer laptops after about 2 years of heavy usage (8-12 hours a day)? My usage is heavy but I normally only have a text-editor(sublime) and browser open(chrome).

Here's what I got from HW monitor:

DO THIS ONLY IF YOU ARE COMFORTABLE WITH OPENING COMPUTERS!!!!!!!!!

If your laptop's fan is spinning this much, then most likely there is some dust stuck in the cooling vents.

Open up your laptop. Then, using a can of compressed air (usually CO2) simply blast all the dust and dirt out of the laptop, including the vents and fans. This should do the trick.

If that doesn't work, then clean the heat sink of the CPU. If that doesn't work, then remove the heatsink from the CPU and apply some heatsink paste. Contact Acer if the above doesn't work.
Update
Three remarks:
1) Prevent the fan from spinning madly while you use compressed air.
2) Before applying new thermal paste, first remove old old paste.
3) Thermal pasted is used in small quantities.
