My computer just turned off and restarted, I was on the internet just browsing...
The fans and cathodes stayed on and then it booted up again...

What could it of been? No BSODs or anything?

Possibly a mains voltage spike. Get a surge protector and it shouldn't happen again.

You got a link to one please?

Sorry, I'm from the UK

So what do they do, is it like a big fuse?

It's saves your computer from getting damaged if there is a powercut. Correct me if I am wrong

Also have you ever overclocked? Were you playing a game when it turned off?

But you can get them just about anywhere to be honest.

They filter out voltage spikes which often cause annoying reboots like the one you mentioned and, on rare occasions, cause hardware damage.

Except lighting strikes. In which case a surge protector won't do jack.

Nope, I haven't OC'ed and I wasn't playing a game when it happened, I was just on the internet.

My power supply is an Antec Earthwatts 380watts, with 17A on each of the 12v rails.
