When i turn on my iMac i see this and a message telling me to restart my computer.
I've tried restarting in safe mode, and reinstalling osx 10.6.1. on reboot and nothing. PLEASE HELP, it would be greatly appreciated.

This isn't clear -
You attempted to startup from the Install DVD, holding c until you could hear the DVD being used for startup, then it finished, and you tried to re-install, and it didn't do it?
(my point - your description was too brief/simple!)

Sorry. when i put the cd in i can hear it reading, and then it ejects the cd. when i try to start it insafe mode it doesnt show the kernel panic screen, just the apple and a blank backround

It seems that you have a hardware failure - but we have no way to determine what is broken. At a repair shop they have spare parts to swap in and figure out what was bad.
Your best hope is to try Apple Hardware Test:
Intel-based Macs: Using Apple Hardware Test

Lacking that, I'm guessing (odds 50/50) that both CDROM drive and hard drive are bad.
- One other idea - buy a cheap external CDROM drive (or borrow) and use your Install DVD to boot up. That will tell us if the computer itself is working (and you can try Disk Utility to repair the regular start volume, too).
