Windows 7 Laptop BSOD

Hi,

I just upgraded to windows 7 yesterday and I have already had three BSOD. I do not know what is wrong, and I need some help figuring out how to fix this.

Thanks in advance

I bought the laptop a year and a half ago

Hello and welcome to Seven Forums,

You have an old driver that needed to be updated - link provided.

Also, I would recommend that you install Microsoft Security Essentials (MSE) as your current anti-virus.
