SO ANNOYING ARGHH!

[BlackLabel]

about every 30 mins my comp desides to crash only when im playing ko sometimes i get these white squares on the ground and capes all turn white so do armbands then armour and weapons turn white.. then some times i can hear my char moving or attacking something and my computer doesn't show it then it crashes.

Does this mean i need a new graphics card or somthing? im using a Geforce atm
