Solid state drive not loading

i was in facebook when suddenly my pc turned off. i turn it on again black screen with message saying to load media disk.

i checked the wires,chsnged them, power good.

gave up and try to repair with windows cd no good. message; said the my windows was currently lucked and i need it to unluck it.

check to reinstall windows, the only two partition i found was my 2 assistant harddrive.

conclusion; my Kingston HyperX 3K 120 GB SATA III 2.5-Inch 6.0 Gb/s is broken.

if it helps: MSI Z77A-GD65 Z77 DDR3 1600 LGA 1155 Motherboards    

i build this pc ike 5 months ago and have been using it for gaming and stuff..

Plug it into other sata ports? change computers? try those before concluding it's fucked.
