Hi guys, I have a mac pro 1,1 quad core, 16 gig of ram, and yesterday during some updates to lion, it went to restart, and and didn't chime and all you could here was an odd click of either a hard drive or one of the super drives, never heard this before, so i don't know what to do, a few people say change the battery on the motherboard, and some say its just a ram problem…. its been working awesome so far, so any realistic "i have the correct answer" people would be awesome to tell me how to solve this because it is a kind of a pain in the ass when it does this. The computer still shutdown and restarts fine.. so no worries there.
