radeon HD 3200 on winXP pro 32 problem with the ati2. driver?

the graphics will sometimes stop with the warning on the screen ati2. etc

i understand that it may be my driver which is old

i have tried the acer site for downloading drivers for the travelmate 6592

and the ati site here to download drivers..

i am afraid i got a bit lost so i thought to ask where i might be going wrong and how to get the driver update

i use my laptop to edit videos using adobe elements 3..for a number of years now and always had to shut down when the warning  came on the screen

would appreciate any help and advice
