Switch to Microsoft Security Essentials or Avast if you can.
I have bad experience with Norton Anti Virus in the past.
I run games from steam and I use Avast as my Anti Virus and no issues so far.

Hi, I really need some help. 1 year and like six months ago, I bought a laptop with the folowing specifications:

HP pavilion notebook Pc dv6
Intel(R) Core(TM( i7 CPU Q720 @1.60GHz
RAM: 4.00 GB (2.93 usable)
64 bits
1GB Ati Mobility Radeon Premium Graphics DirectX11.

Six months ago I had to change the motherboard because my laptop was the slowest thing ever, and often it crashed. The first time I had troubles with my laptop was when I installed and ran COD and Warcraft. It started with a few blue screens, and then it was imposible to work with my laptop

Well, after the new motherboard I bought an external fan and haven't had any trouble until now: Las week I installed an ran the game Borderlands 2 in my laptop, the game wasn't running and two day after that again a blue screen appeared, now I'm afraid of loosing my laptop, and google chrome doesn't run like it did before.

My question is why if my computer have those specifications I can run perfectly any game that I want?
And that if exists any link between running these games and the crash of my computer?
What can I do?
