Canon 60D won't turn on?

I have a canon 60d that is about a year old. About 2 months ago it just completely "died", used it one day, put it back in my camera bag, went to use it the next day and it appeared dead, even though I just placed a fully charged battery in there. Tried different batteries, battery pack with double A batteries, nothing. It doesn't flash any lights, doesn't make any noise or shown any signs of life when switched on.

Any idea on what it could be?

I'd hate to spend $400 or whatever it may be, to be sent ti canon to repair it when the body itself is really worth less than that. I'm just feeling as if I might as well invest that $400 into a new body.

And yes I have tried the switches on both the battery compartment and memory card compartment, nothing at all.
