ok i popped in the tiger intall disc to do an archive and install cause i was having some speed issues and thought it might help, but it won't restart it gives me this "no exit" type sign and i eventually unplugged it and plugged it back in and the same thing happened, i have EVERYTHING on this computer, and i don't know what this sign means but it obviously can't be good

i need help ASAP

thanks

also, it starts off as the apple logo then changes to this symbol after about a minute of inactivity

Reboot and hold Cmd-Opt-O-F at the chime, then type:

reset-nvram
set-defaults
reset-all

The system will reboot. Hold Option at the chime and boot from the DVD, and see what happens.

The fans going at full tilt is normal :)

Yeah, it does sound like something's wrong with your disk. Try making a copy of it, then boot from the copy - sometimes this helps.

alright weell thanks a lot

What kind of disc is it, and where did it come from? Is it the system restore/install disc that came with that particular computer, or one that came with another one of your macs? Also, have you tried putting it in while booted, and then rebooting from the option in the system preferences -> startup disc pane?
