Hey Pete, The power supply shouldn't be the problem unless you have a bunch of drives hooked up to it. I've been using a 7200 power supply to test 9500 configurations on my test bench. Usually with three drives (two hard, one CDROM) attached. I think you have a typo up above. Either that, or I'm confused. You have installed an 8500 motherboard in an 8200 case, correct? The first thing I would do (because it's the least trouble) is to try the Early-PRAM-Zap. Shall we call that EPZ from now on? :-) Was it Peter in Japan who coined the "RAM Sandwich" term. We need someone to come up with a snappy name for this procedure. Anyway, in case you missed it in earlier postings (most recently from Howie) get your hands ready, power on the computer, then ***BEFORE*** the chimes finish sounding, hit the cmd-opt-p-r keys. This usually brings up the video on a chiming black screen freeze. If that doesn't work, recheck the power supply connections and such, of course. You might want to check the reset and power buttons on the motherboard given the recent thread. If there's no joy from any of that, disconnect all your drive cables from the motherboard. Take out your VRAM and install a PCI video card that you know works. Remove any other PCI cards. Be sure to remove any VGA adapters from the built-in video port if you are using one. Install just one stick of memory, any size will do. Just make sure it's one you know is good. Now try again. If you get to the flashing question mark at this point, then you can start building things back up one or two at a time until it stops working again--assuming it does. That last paragraph is just general "I don't know what's wrong with it, let's try everything advice". But there's sense to it. Hard drives and PCI cards don't help if you're not even getting a start up chime. Once you have a chime, they still don't help if you can't get video. So disconnect all that stuff. At this point, your goal is to get video. Once you have that, hopefully it will go all the way to the flashing question mark. Once you get to the flashing question mark, you can start worrying about hooking up a working storage device with an OS and installing enough memory to run it. I hope that helps.
