Well.....heh, heh.....I used to leave my PS2 on all night everyday.......
That's because I would wake up the next morning and began playing where I left off, 'cause I'm too damn lazy to turn it on again. (Yeah, I'm a lazy ass cow) But, then, I realized that the vent fan was collecting a lot of dust, so I began turning it off. And, as for the sudden shut down....I don't think it happened too much. Only once, and that was during a lighting storm, but that was a few months(?) ago. Thanks for the advice, maybe I'll try that, then I'll see what happens. That really sucks about your PS2 repair. See? This is one of the disadvantages about the PS2, I think. I had no problems with the PSone, except for the fact I overplayed it and it burnt out....
