I have a 2008 iMac and it continuously goes to the grey screen tell me to restart the PC. I have reset the PRAM (alt+command+p+r) and even hooked it up to a macbook with a firewire and erased the iMac. I am trying to boot off the CD and no matter what I do ....... Hold C or Hold Options it does nothing but go back to the grey screen. What the heck do I do :(

Have you made any changes to the machine recently? New RAM, new HDD, etc.

I forget if AHT is built in the or if it's off the install DVD for the 2008 iMac's. On startup, try to press and hold "D" to see if the AHT will load.

I did that and came back with no errors :( Just wont let me boot off anything...... Everything I try from the CD, to External bootable HD gives me the grey screen. Keep in mind the Main HD is formatted now

If you're unable to execute any pre-boot commands, there's nothing much you really can do but to take it to Apple for repair. Hopefully you have AppleCare because I'm thinking the logic board is gone bad.

I'd agree here, if nothing is working, then it is probably a logic board issue.

If you can't get it to boot from the DVD, then not really.

How much does it cost to have this repaired?

You'd have to ask Apple, but logic boards usually run upwards of $600-800.
