How do i get to my GPU

I changed the thermal paste today on my CPU and found this thick layer of dust covering the heatsink part that is connected to the fan and after cleaning and changing the past my laptop is about 20C cooler, but i noticed that my GPU was still very high and when i play magicka it would bumped up to 90c after about 20 minutes.

Unlike the CPU the GPU is under the chassis. Do i just remove all the screw on the underside and it comes off? I tried reading the guide and didnt really understand cause there werent that many pictures and i have 4 screws that wouldnt come off!!!

 

The disassembly guide clearly labels all the screws you need to remove. The graphics card is the hardest part of the laptop to access and the last step on the guide.

This is the picture you should refer to: Imageshack - 18mbremovedbottomp.jpg

Note: To properly maintain your laptop, make sure to clean the vents every two weeks or so with a can of air to prevent the accumulation of dust, which leads to overheating.

 

So basically i have to take apart the entire laptop which includes the monitor and keyboard?

 

Yes. That's what happens if you don't clean your vents frequently enough. It might sound like an inconvenience at first but you'll start to appreciate the labor into building your laptop.

 

There are a few screws that wont come off. I believe its the Chassis screw but for some reason my screw driver works on every other screw with no problem......

 

It's a daunting process, to be sure. I was so scared of screwing something up that I took about two hours to do it (three if you count the constant breaks).

Just have the information you need available at all times. I had my Android with a youtube photo walkthrough beside me the whole time.

Besides not losing any screws, be EXTRA CAREFUL with any and all Ribbons. Those that connect your keyboard, and the plate at the top with your power and volume buttons. Those ribbons are thin, and if they're damaged you'll have to replace the whole piece before you can even turn your comp back on.

That being said, the entire process is doable, and makes a big difference. Canned air through the vents is not very effective, and in my case just caused dust to clog the fan so it burned out.
