So basically, I don't know whats happened, My mac suddenly just stopped and i couldn't do a thing, so i unplugged the bastard, plugged it back in, started it up and its been roughly 30 minuites now and it just wont boot passed the apple logo

I have the 21.5'' Late 2010 model With 12gbs of Ram installed with a Core 2 Duo.
Keyboard and Mouse are wireless.
I've tried Holding down CMD, OPTION, P + R but that doesn't work.
Im willing to do a full restore to a backup because the only thing ill loose is a season or 2 of South park and Family guy
(I backed up about 2 days ago) - The only thing is I have no idea on how to restore my mac at the boot screen -.-
I've also Tried Safe Boot But that failed
I live in Dubai At the Moment so taking my Mac into a Store is basically....Impossible.
ANY help at all is VERY VERY VERY much Appreciated - Thanks in advance
