That is called a kernel panic.

Your computer has the infamous 8600GT, which is known to be a ticking time bomb(they will all fail eventually, due to a manufacturing defect). The "junk" you saw on screen is a tell-tale sign.

If it's not booting correctly, it's sad to say that this is almost 100% sure to be a logic board issue. The whole logic board will likely need to be replaced, which is more expensive than what your computer is worth nowadays. Apple had extended the warranty to 4 years on the logic board on those computers due to a class action suit against nVidia, unfortunately your computer is out of the 4 years and the program ended on dec 7th 2012, so you're out of luck.

If money permits, you should simply buy a new computer, yours is most likely dead.

Of course there are ways of fixing the nVidia GPU problems, but they are risky and generally temporary. It involves pretty much the baking of your computer in an oven or with a blanket.

Mostly because stuff breaks, and while it worked the other day, its not now.

If you're unable to boot up the computer in either OS, or your system install disc then its hardware. If you can take it into an apple authorized store to have them fully diagnose the issue

Have you tried Apple Hardware Test? If yes, what are the results?
Also, try to run Ubuntu Live CD (latest version 13.04 64-bit download link),
it would be like a temporary full scale operation system - if it boots ofcourse
