Kokeilin tässä pelata tänä iltana medal of honor - allied assaultin demoa, ja sain seuraavan virheilmoituksen:

Osaatteko sanoa missä on vika? Kokeilin erästä toistakin demoa ja sama juttu. Kone on kuitenkin sen verran uusi, ettei siitä pitäisi kiikastaa: 1,4ghz amd athlon, 512mt ram.

Kiitos avusta!
