strange ps3 issue

i was playing sc5 in a room and the screen gone black.my brother lost his conection but my ps3 did like restarted.but i were online again.

it's like if i have quitted the game but the ps3 quit the game by itself.

i'm playing final fantasy 13 these days.i hope this is just a rumor than final break the console.

what do you think it's happened.do you got the same issue with your ps3?

in fact i got kicked out of my game 3 second and i was still online on the psn.i don't know what going on
