MBA mid 2012.. shut off twice randomly.. now completely silent (cant hear the fan)

[pcacd001]

So last night I was just doin some browsing with my charger plugged in, and all of a sudden my MBA just shut off. I turned it on again, and after 5 minutes it just shut off again! I reset PRAM and it hasnt happened again today.. but.. Ive noticed the computer is COMPLETELY SILENT. I can't hear anything under the hood, no fan spin whatsover.

anyone have this problem? and how can i diagnose if my fan is actually dead?

any help appreciated, thanks.!

Mine is now dead and won't bloody recover
It looks like the SSD has given up the ghost! It's only 9 months old
