INTEL Chipset Upgrade

I have an Intel Chipset GM965 in my VAIO laptop. I cannot remember how to update the drivers for it. I remember I think I have to uninstall the old ones to upgrade to the new.

My problem, if anyone can be of further help, I am trying to play Battlefield2 on this computer and I got jipped in the graphics card when I bought it. I was supposed to get the one with the GEFORCE. Anyway, the game starts and goes to black screen like it is loading, and then quits to desktop. This problem happened a few months ago and I came on here and asked for help and we pretty much determined the drivers needed to be updated. Well it worked. I was able to play for a long time. Then a couple weeks ago, it randomly just quit working. It went back to doing the original problem of starting and then crashing to desktop before the game even loads. Well nothing was changed. I didn't update drivers or anything I didn't make any major changes in anyway. It just simply stopped working... so if anyone has any clue on what to do other than update my drivers... please help. Thanks.

 

BTW, I do have the new update from intel downloaded, but when I try and load it, it says it is not validated for this computer, some crap like that.
