Cant get games to display full screen, even with 'maintain ratio'

Hi
I have a hp mini 210 netbook.
Im trying to run games like broken sword on it.
In my previous windows 7 instalation, i just selected 'maintain aspect ratio' from the display properties, and it gave me a full screen game.

I had a terrible virus, so had to format and install another windows 7.

I noticed the graphics driver is a bit different, and now when i select 'maintain aspect ratio', it makes no diffference whatsoever.
how to actually get full screen again??
thanks

Trying to answer from my android app. Did you install the newest driver from Hp? What is your gpu make and model?

I found a great thead on here somewhere.
It says to go into the properties of the game shortcut, and tell it to display the game in 620x480 resolution.
Not quite the way i was gonna do it, but it worked.

great, its nice that windows 7 has all these useful options... when you knwo where to look

Thanks

tried all that
it seems a different system than i had before.
coz i dont have all the hp junk on it now
it doesn operate the same.

same for th ewifi driver.. which just doesnt work now...
so its either 'use our junk windows 7 instalation, or dont use windows 7 at all'
i guess.
