Well, my 17" PBG4 (1.67, 2GB, 100GB, Super, Airport, BT, 10.5. 8) has decided not to work anymore.

I was using it one day when all of the sudden, the power supply indicator light turned RED and it shut off (Note: I have tried several power supplies). I let it sit for a while, tried to turn it on, and not a whole lot happens. The Superdrive makes a noise (as usual) and the fans max out for some reason, but other then that, no chime and no video.

Any ideas? Likely a Logic Board issue?

Thanks
