MBP 13' Won't boot from CD or external Drive

Recently my MBP 13 (newest version) occasionally crashes with the grey screen death which forces me to hard shut down. This led me to believe my directory may be corrupted so I tried to boot from my external OS X (Snow Leopard) with DiskWarrior installed to do the repair. Unfortunately, when the grey Apple logo shows up, the computer crashes again.

I tried again using original recovery CD to boot hoping to use Disk Utility, but it does the same thing where it crashes at the Apple logo.

I can't seem to figure out why. Anyone have experience with this issue? how do I resolve this issue???!

Thanks

 

Thanks for the reply Hell.

I did the PRAM reset, came into Safe Mode to use Disk Utility. It said no issue found on the drive. However, I'm still having issue with booting from external drive.
