Any solutions for this problem?

I just got my hands on a machine with the same issue. I do not know the history of this machine and am pretty confused as to whats going on, and cant seem to find a thing online regarding this issue.

Please let me know if you have found a solution, and if not could you explain the behavior of the machine before this occurred?

Thanks!

Everyone is looking for an answer without doing the diagnostics! Are you up to it?

完成的

The Mac Pro has a total of 12 diagnostic LEDs. It would be helpful if you try specify where the red light came on or try to take a picture of it.

So far we've not encountered any problems with our Mac Pro's so I can't offer a sure thing here. The things I look at across the board is if the system was plugged into a good surge suppressor or UPS unit.

Next knowing some of the symptoms or issues that preceded. Sometimes this offers a clue on where to look.

Did you try checking the connections to see if any are loose here?
