Does it still have power?
It could be a bios thing too.
If you're not comfortable messing with hardware then take it to your schools's tech center. Stupid **** happens to PCs all the time even if you don't do anything.
Someone may have dropped it, but yeah the power works, Im using it right now. Aside from that there's really nothing wrong with my computer.
