Help updating drivers ATI+ATI - see inside !

Hi,



I'm having trouble with my videoscards drivers, specialy on Battlefield 3.

I can play about 15 min to 1 hour and then the game freeze and crash...

I 'm trying to update the videocards driver because they're actually from 2011.



Here is the specs:



HP Pavillion Dv7 Notebook PC

Windows 7 x64

Switchable Graphics - AMD Radeon HD 6650M --- AMD M880G with ATI Mobility Radeon HD 4250



I can give more infos if it's needed !!

Thanks very much

Romain



ps: sorry my english, i'm french and i do german and spanish at school...
