Hard Driver Corruption?

Hey guys I figured I'd ask the general public before taking it to Customer Service as I'm not much of a technical wizard :P

I think I have been getting Hard Drive corruption on a rather regular basis.. I will install COD4, Crysis, Wow, etc, and the games work great for about a week, then I will start getting errors (Game faults and closes out or it won't even let me start the game saying 'Please Reinstall').  However now I can't even install Wow..  I've tried both CD installation and Digital Download and during the install sequence it keeps giving me corruption errors. 

I've run ever test that comes with the computer itself and everything says my computer is in perfect shape.  I've also installed the latest drivers.

Should I just try reformatting and starting anew?  When searching for solutions I have read that a lot of WD Raptors have issues..  maybe that's the cause?  Any help would be greatly appreciated! Thanks!
