Recurring kernel panic version 10.7.2

[alex1984]

Since I have upgraded to Lion I have been experiencing recurring kernel panics which are making my mac almost unusable, I am hoping to uninstall Lion and re-install Snow Leopard. Unfortunately I don't have the knowledge to do this and would like help as to how I could re-install Snow Leopard onto my Mac.

The most important question is "why is it panicking?"

Boot in verbose mode by holding down command-v. Then, when it panics, it will spew a bunch of text on the screen. Take a picture, and post that on here.
