Feb 21, 2013 11:56 AM in response to Bill289by BDAqua,I'd give it a try, it's been known to cause problems... it should make a new one.
Also...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.

Feb 21, 2013 5:25 PM in response to BDAquaby Bill289,I deleted the sleepimage document, booted from the restore partition, verified the disk which did not need repairs and repaired permissions.
I again put the computer to sleep and it restarted when awakened.
Any other ideas?
I sure do appreciate all the help and suggestions.

Feb 22, 2013 3:19 AM in response to Bill289by japamac,Did you ever take advantage of the replacement program (now expired) that was offered for the 2600 XT cards?
I'm wondering if an issue within the card is tied to the restart at wake from sleep....
Along the same lines, did you ever update the firmware for the 2600 XT?

You don't happen to have a different graphics card laying around that you can try, do you?

Feb 22, 2013 7:37 AM in response to japamacby Bill289,I don't have any extra graphics card nor did I do the replacement program.
I tried to update the firmware but it would'nt let me do it, said the update requires Mac OSX 10.5.2 or newer with the Leopard graphics update.
Any other ideas?
Thanks...

Feb 24, 2013 4:02 PM in response to Bill289by Grant Bennet-Alder,The 2600XT is getting really old, and has trouble keeping up with the demands of systems like 10.8.2.
You should consider replacing it with a newer card. The Apple-firmware 5770 is pretty good and works in all models of Mac Pro. Drivers first appeared in 10.6.5. costs about US$250.
