Macbook Pro Retina Freezes!

Hey guys,

Lately I've encountered a problem with my 2012 retina 15" Macbook Pro: it freezes! I've noticed this happens whenever I:

• Make a video full screen on Google Chrome
• Try to play any video games (i.e. Dota 2, Starcraft)
• Intermittently (it's really not fun when it happens randomly)

Since it started happening, I have erased everything on my hard drive and reinstalled OSX Mountain Lion (10.8.2) on my computer, and have still encountered the problem. I have a feeling it's a graphics card problem (I use the Nvidia GeForce 650M 1024MB), as any YouTube or Vimeo video flickers and has strange thin lines that flicker from black to white rapidly whenever I play a video.

To try to help you guys help me, I looked at my console log and this is what I found when my computer froze briefly:
