I think the larger question is whether or not you can still boot to the installer DVD.
- Leave the DVD in the drive, restart the machine and hold the D key down to start to the AHT part.
- Select the extended test and before you run it click on the Hardware tab to see if it sees all the RAM you have installed. Any RAM flagged as bad will be written in red text.
- If you see no red flagged RAM then go back to the Test tab and run the test.
Just remember, you said you have a Time Machine backup. I found it easier to restore from backup (took about 1.5 to 1.75 hours on my Mac Pro restoring about 175 GB).
That is why we have Time Machine.
Select the last backup before the update to 10.5.7.
Holding the D key down with the install DVD leads to the same panic error message that I have described. Is there a way to force the machine to boot from the Time Machine backup or have the machine look at the backup and restore things to how they were yesterday before proceeding to do anything else?
Restoring from a TM backup requires booting from the install disc.
Try removing & reseating the RAM in the machine, as well as running on first one module, then the other and see if that solves things.
See this article for how to remove and reseat RAM:
