    I installed an app called DriveGenius3 and it told me that my hard drive (SSD) was corrupted. I ran disk utility and it confirmed that it is corrupted. I am trying to repair the disc but I am unable to bootup with the install disc (I've tried the pressing c thing and everything) ... ?

    Try selecting the Mac OS X disc as the startup (boot) disc in System Perf?

    Another option is to use fsck: details here.

    On startup, hold down the Option key. It will then show you the available startup drives and allow you to select which one you would like to use.

    What's the specific issue Drive Genius 3 is notifying you of? Some issues may not be able to be repaired correctly from the startup disc. With things like catalog corruptions, even though they can be repaired using disk utilities, they don't always stay repaired and it's best to backup your data, do a clean install and start fresh.
