MAC PRO 2.8 quad-core Intel
4 x 1GB
2 X 500GB 7200 ATA
ATI RAEDON HD 2600 XT 256MB dual link DVI
16X superdrive


computer froze today -- it was running fine this morning... i went to restart it and now it won't restart... no history of this happening before...

it will shut down if i force it -- but IT WILL NOT BOOT UP...

after i turn it on -- it starts up as normal with a chime and goes to the GREY SCREEN WITH THE APPLE LOGO and the SPINNING WHEEL...

but then the APPLE LOGO BECOMES A CIRCLE WITH A SLASH THROUGH (international "no" symbol) -- the SPINNING WHEEL REMAINS SPINNING...

and then it just stays like that wheel spinning and "no" symbol...

i've tried starting it holding down "shift", holding "option-command-p-r", holding "d", holding "c", and holding "option"... with the same results each time...

i ran DISK WARRIOR on all the disks... and tried staring up with no external drives...

and i've cleaned it thoroughly of dust...

PLEASE HELP!!!

THANK YOU!!!

Can you boot from the Mac OS X disc?

From the apple website:

Circle with Slash - could not load boot.efi, or some other issue

I would take an OS X disc and boot to that. Try reinstalling the OS and reformat the boot disk if you have to.
