I have been playing for a few days with the new update (ie 2.01) and had no problems. But yesterday my system was on standby and I put in my Madden 08 disk, the system would not start properly and has not since. I can turn on from the back and the green light turns on, but other than the disk drive nothing actually starts. None of the usb ports work or anything. I have tried leaving the system off for like a day, but problem still persists. Also tried the 'reset' feature of holding the power button but system will not reset, just turns off.

Any help would be greatly appreciated as I really don't want to have to send the system back to be replaced.
Thanks

Yes, I can eject the disc with no problems, the whole disc part of the system seems to work fine. I can put in and remove any disc I want, but whether a disc is in or out, the system will not actually start

I have tried the reset approach, but the system appears not to reset as it should, it just turns straight off again, without the beeps.

And I cannot tell if the system is recognizing the discs as nothing is being output on the screen, it is as though when i turn the ps3 on, only the disc tray is booted up and not the actual system itself.
