10.7.3 frustrations....

I updated three Mac's yesterday using Software Update. Two seem to be working fine.

The main server (a two month old Mac Mini) will not boot...just sits in a grey screen with the little wheel spinning.

I let it sit, the monitor sleeps, but nothing will wake the monitor back up.

I rebooted into the Restore and am trying to restore to just before the update using Time Machine. The screen keeps sleeping and will not wake up again...I can't tell if it is restoring or restored or what!?!?!

Is there a way to keep the monitor from being put to sleep?

Will I have to reinstall Lion and then restore?

So frustrating since this is my business's main server...so none of our business software will work today!
