Blue screen ATI Radeon HD 2400 pro on a Vostro 200

Dear Members,

I have a problem concerning my ATI Radeao 2400 Pro video card.

After a while my systems notify a problem, concerning the display preformance, and after a short while of flickering of windows / black screens he turns to fatal with result a bleu screen.

Enclosed a copy of the notification.

I have already updated the driver from ati but without any result.

I am using 2 screens from dell 19 inch

Is there somewhere who is able to help me?

Thanks!
