G5 has died - won't boot or recognise HD

[gringo purves]

Hi all, first post on here begging for help!
I have a G5 tower, PPC, and after opening it up to see if an old soundcard would fit the slots, I closed up and - nothing.
My mac is whirring, fan activating as normal etc, but I'm getting nothing at all on screen, not even the dreaded question mark.
I've tried booting from restore discs, which works fine until I specify which disc to restore/install, where the installation program doesn't even see my HD as a location.

Any ideas? Logic board fried?
Thanks in advance!

If Disk Utility can't see your HDD, it's probably bricked, unless you accidentally disconnected it while your computer was open. If the logic board was fried you wouldn't be able to boot up with the installation disk, so that's ok. Is there another HDD you have to troubleshoot with?

Fixed - a loose HDD, simple as that. Glad you lot aren't as dumb as me..!
Thanks for the advice

Unless I'm very much mistaken, Power Macs have motherboards, not logic boards.

Anyway, I'm glad to hear that you got everything sorted out.
