Sounds more like a p/s problem. Have u checked your logs in console? Can you remember when it happened? Look that time up in the system logs.

Re: MDD just shuts down by itself opinions please.
I had a quick silver do this to me. It was a bad power supply. Check if you can hear any arcing going on where the cable goes into the machine. If so, you PSU has had it. Also sometimes the power cable used to work itself loose, which probably ended up killing the power supply in the first place. Quick Silvers were known for this.

Re: MDD just shuts down by itself… opinions please.
I'm now convinced the power supply is the weakest link in the MDD. I peaked at having 5 working systems. 1 bought new, the rest on eBay. The bought-new was the first to die, and recently, another. Both fails are pretty certain the PS. An intermittent problem is tougher to diagnose, but I've not seen PRAM battery lead to this symptom.

Well in the last 2 weeks I had this with a QS'02 and a MDD. Had this never before. I was checking all: PS, PRAM-bat, connections etc., and all OK, when one of my grandsons (he is 9 yrs old and I'm 68 haha!) said: Hey Opa (= dutch for granddad) your Macs are dustbunkers! I looked and he was right!! Being curious, I first restarted both Macs while watching what would happen. I used iStatPro in Dashboard to observe the tempartures of the HD's (I have 3 in both). And I saw following: After 96 minutes the SU-disk of the MDD came to 61 degrees C and the MDD shut down. After 128 minutes the SU-disk of the QS came to 64 degrees C and the QS shut down. Then I totally cleaned both an restarted them. Now they are both running already for 3 days + without any inclination to power down! Perhaps an idea for you also! Try it, because it will never hurt anything but will help possibly!

The other night, the machine just powered down all by itself ... looks like PRAM battery? clock is doing the usual mishap... A real long shot but perhaps a defective keyboard or keyboard cable/connection. I had the the shut down problem on a PCI Mac that had a failed keyboard. Don't recall any clock problem however. Try switching keyboards and cables. Overheating or a failed power supply as discussed is probably a more likely culprit. --glen -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
