okay, so I have the original 60GB PS3 model and I was just about to play the Uncharted 2 demo when my PS3 turned off.. I thought it was a little weird but shrugged it off, so I turn it back on and start the game again after a few minutes it does it again only now it doesn't even turn back on :(

when I try to turn it on it makes the beep noise then the light turns green and then yellow for a split second. After that it shows the red light just flashing and the ps3 won't turn on.
