Kernel Panic at start up

[kanvas]

hello
i'm getting a kernel panic at start up and my mac wont boot up.
i dont think its the RAM because the LED's are not red on the risers. When i start up holding "option" and select to boot up from the DVD it goes to the apple logo and on to the kernel panic. When i start up windows via bootcamp everything works fine.
I've fsck. reseting PRAM, NVRam, nothing seems to work. I'm stuck please help.
THanks

Is it the installer that came with the machine or a retail version that is as current as the machine?
