game chrashes on laptop

i installed GW on my laptop yesterday because it has more RAM and it loads faster...
But when i was playing the game today, i went to a Merchant and i saw that some icons were pretty weird
it was like a icon like a person with a yellow hat on or something and then it crashed..
so i restarted GW, tried it again and the merchant was ok so i could play, for a while..
i went to another merchant and i pressed the Sell button and the game crashed again.....

help !

the icon with a person with a yellow hat means under construction- it means the icon hasnt been completed yet. As for the crashes, are you running the minimum req. of the game?

ive got a 1,70 ghz and 512 ram
i saw 1,70 is alot for a laptop btw...
dunno what graphics card, but i dont care playing on low...
but, why do i get these under construction icons?
