I was given as a present a Toshiba Satellite L645 laptop with 6 GB of ram with windows 7.

And I keep getting this really weird, irritating lag with games.
On the first day I got and turned on the laptop it was fine with games, 100%, awesome. But after that whenever I play games I get this weird lag.
The games itself run amazingly on both min and max graphics, but every once in a while, maybe once every minute or two, it freezes for half or more seconds. On a particular game, Dragon Nest, it is really bad. It would freeze for a few seconds every time I use skills, and it would freeze itself up as long as there are a number of enemies nearby.

I tried many things including CCCleaner, updating to the latest drivers (so yes don't tell me to update my drivers I already have) and ... some other stuff I can't remember at this point.
I did managed to fix it earlier using a Core Parking fix here but when I turned on my laptop again some time later the problem has come back.

This is really irritating, especially since I know I'm getting Guild Wars 2 for Christmas tomorrow, and I want to be able to play it.

As someone who is pretty dumb as far as computing goes, please go a bit easy on me.

while your system technically meets the requirements, the mobile video solution isn't as good as the discrete part (desktop equivalent).

1: reduce your video settings in game to lowest possible and see if that helps.
2: used some canned air and make sure the laptop fan is clear of dust. Just give a quick squirt or two, don't overdo it.
