Well, In this month (December 2012) my laptop (Asus G53SW) is turning a year old with me. Well this laptop has worked perfectly, all it's internal components have been working top notch. Except for the MANY design flaws, Loose power jack pin, depolarized screen sleep magnet, Lower bumpers sticking out, etc. (Things that you WOULDN'T expect from a computer of this price). I've already spent some money repairing it each time and those flaws haven't been major problems at all.

But I'm coming today, because recently (over this past 20-30 days) my laptop performance has been at an all time low, (for example, I've been playing the same games that I've played a year back, and I had to lower the specs of the games because they started working really slow, and sometimes froze). ALSO this computer has always been REALLY quiet, but over this period fans have started producing a lot of noise (compared to before).

So my question is: How can I fix this problem? (really frustrates me, after paying A LOT for this computer, and having paid also a reasonable amount of money on repairs).

I've already uninstalled/deleted a large quantity of my stuff, (hard drive has a lot of free memory), I've run the antivirus, also cleaned the registry (with tune up). but still the computer has a very low performance, and makes a lot of noise.

I have also read that cleaning the fans/radiators may help with this.. I wanna know if doing that my performance of my laptop will return to normal.

Any help will be appreciated.
Cheers.
