My computer is dead :(

[Sethomas]

Last night, I was brushing my teeth and I heard my computer turn off without the regular sounds of logging off and shutting down. I tried to turn it back on, but it just made a soft twirling sound and then nothing happened. It doesn't power up at all. I figured maybe the power source was damaged, but the light on the motherboard is still illuminated so I can tell that at least some power is getting through.

What the hell is the problem?
