afew weeks ago i went and got myself a new stick of 1GB RAM, when i put the new stick in the machine i saw the computer was picking up the ram and everything was cool. But about 1 min later it would restart the machine and start all over again. I grabbed that Bastard ram and got back to the place i brought it from and they did a mem test and reported it was Dead, so they gave me a new one for free. just go send it back mate.
