Okay, so, basically....

My Mac is set to sleep after about 30 minutes of inactivity. I've had it for two years, and it seems to have not had any problems with the sleep function in the past... Anywho, I left my computer to go to bed, and when I came back to it this morning, something weird happened...

It LOOKED like it was in sleep mode, but I could not wake it, no matter what I did, and the fans were roaring rather loud. I had to completely shut down and boot again.

I'm afraid it might happen again tonight, so I want to nip this problem in the bud before then.

Help me out.

Sounds like a bad freeze, this may be a symptom of things to come so if I were you I would backup your system in case this is a more serious problem. You could possibly have a bad logic board, so I would just be careful with the computer and see what happens. Sometimes there are one off things, if it continues you can run the hardware test to see if something pops up or swing by an Apple Store and have them look at it if this continues.

Has this not happened to anyone else before?

I think it might have had something to do with my Alarm Clock program. It didn't go off this morning. Maybe it crashed my computer instead? @_@

This is nothing more than a freeze while attempting to come back from sleep. Usually it is just some minor permission problem when the system trys to restore the system from the RAM. Repair permissions and be done with it.

IF is occurs regularly, then it may be RAM, HD, or logic board problem, but just happening from time to time is no cause for concern.

How would I go about repairing permissions? I've never had to before.

I have never heard of permissions issues causing a lock up of any kind. The symptoms you report sound similar to some of the problems which afflicted the recent iMac models, which is why I asked:

What model Mac is this?

It's an early G5 iMac. 1.8 GHZ 2 gig ram. No iSight.

Well those models had a high rate of logic board failures, but I wouldn't jump to that conclusion just yet. I agree with the above post to the extent that it could be a hardware issue, but also not to worry unless it happens again.

Happens to our G5 iMac occasionally. Looked inside awhile ago and found bad caps. Probably related, but the G5 is holding on for dear life. :)

I find unplugging and replugging in the iMac before rebooting limits the chance of it happening right away.

reset your PRAM by holding down command option P and R when to computer is turning on.

Why would resetting the pram fix a kernel panic?

If this problem happens again, you can physically inspect the logic board for puffed out capacitors. This is a fairly common problem with certain iMac G5s and is covered by Apple for a certain range of serials. You should contact an Apple authorized service provider and ask about this issue.

you know its bad for computers to be running all time. think about investing a couple bucks and buying a cheap alarm clock.

this isn't necessarily a kernel panic.
