I have intel 82945g integrated graphics controller in my cpu and i have lost its setup ,now i am unable to play games

try checking the system requirements of thw game.. if your unit doesnt meet the minimum.. you cant play it.. try upgrading your graphic card.. if you want to play games with high graphics..

From looking at the stats, the game requires a non-integrated video card. Therefor the game will not play on your laptop.

I install Burnout paradise the ultimate box and got an error when try to play the game...
this machine gpu does not support shader model3 which is required to run this game.
I have Intel(R) G33/G31 Express Chipset Family, Integrated Graphic
Intel Processor Dual CPU e2200 @2.2GHz
Memory 1.99GB

What can i do to play this game

Unfortunately you can't unless you upgrade your system. The error means your computer isn't powerful enough to play the game. You either need a new computer (recommended as Vista is way out of date) or a graphics card good enough to play the game that is also Vista compatible. New computer is definitely the recommendation here.

When your computer loads, after you power it on, it gives you an option to go into the CMOS. You can disable integrated periferals there. If you don't know how, check your system documentation

Driver

I highly doubt that the driver will do much at all to the shaders. You probably need a new graphics card, to run the more mainstream games.
