Well ive have sent my ps3 today, i think the problem is that it has dust, becasue the other day while testing for the error it said call of duty 4, then 5 minutes passed and it jumped to the play online, lan, split screen options. Ive got some thigns to cool the ps3, but would you recommend me to take the upper part out and cool it to see if it has dust, or just send it. Hope you understand me, my ideas arent pretty clear.
