I'd like to if anyone has experienced this:

I was playing Gta4, when I heard a 'pop'. I was immediately disconnected from PSN. I used a wired connection and the ethernet port on the back of PS3 no longer lights up (green light).

I switch to wireless and the wireless LED in front does not light up either. I restart PS3 and it takes 4-5 mins to load up XMB menu and then my controllers no longer sync with my console or only syncs until next restart.
