Eee PC 1015PED issues in Cataclysm zones

Ive been experiencing some issues in several zones, mostly zones that were somehow affected or created with Cataclysm.
For example, when I enter de Dwarven District in Stormwind, the screen does a sudden glitch and the screen turns black. I still listen to the sounds and music of the game but just for a few seconds, then the PC crashes and I have to restart and ask someone else to login with my character and move her away from that spot.
This issue happened aswell in Deepholme at the entrance of the Temple of the Earth, and in The Lost City of the Tol Vir (dungeon).

Ive already tried to speak with a GM in game about this issue and followed the steps advised, with still no luck.

I have an Eee PC 1015PED 2 GB RAM with Intel GMA 3150 graphic card.

I know I shouldnt expect much but at least I thought I could play with the minimum settings.
FAIL (the browser should render some flash content, not this).
