Hi everybody.

So, I have been having a problem in the last couple of weeks with my laptop while playing Modern Warfare 3 online (or any other game for that matter, applies to Batman: Arkham City, Modern Warfare 2, Battlefield 3, AC: Revelations)
After a few minutes of gameplay (7-8 minutes), my games drop from solid 70+ fps, some of them 50-ish, but never under 45, to 15 fps and lagging like hell. I don't know what's the problem, I'm playing on a decent laptop that meets the system requirements and I did not have this problem until like a few weeks ago.

Here are my laptop's specs :

CPU: Intel Pentium CPU P6200 @2.13 GHz (2 CPUs), ~2.1GHz
Memory: 3072MB RAM (DDR3)
DirectX Version: DirectX 11
Video Card: nVidia GT 520M, 1024MB4

The laptop's model is Aspire 5742ZG and I'm using Windows 7 Ultimate 64-bit (6.1, Build 7600)

What should I do to make the games run like they used to?
Thanks in advance.
