Mac G5, what is pin set up. my computer doesn't see my new hard disq WD1002FAEX

The problem is not with the camcorder. The problem is with the capture settings.
You can capture video via firewire or USB. Imovie has a capture mode that syncs with nearly any camcorder. Roxio Toast will also sync with a camcorder. Be sure the camcorder is connected and that the computer recognizes it. It may take a few on-off cycles to sync itt.

possible bad cpu fan or system fan..................meder's tv service

go to manage options then disk management

The ram might not be the right one. The ram that you put on there must be apple.

Hello
You can check your hard drive's health at startup pressing command-s. you will see a black screen with white text. simply type "fsck -f" and press return. It should check your drive and tell you if something goes wrong with it, and repair it if possible. Then type "reboot" and press enter to test.
It this does not help, you can press the shift key at startup. It does the same thing, but also disables the extensions at startup, this will help you to find out what the problem is. The startup will be longer and it should ask for your admin password.
If this still doesn't help, you might have a hardware problem (hard drive). You can try to backup your data, erase the disk and reinstall the system. To backup you need another Mac, and a firewire cable. Press the "T" button at startup, this should set the Mac in "target" mode, allowing you to use it as an external hard drive. Then connect the firewire cable between the two macs. On the mac that is OK, you should see the hard drive icon of the other mac...
Hope that you will succeed and that it helped you someway

Bad capacitors often cause the no-turn-on problem. This page has a good picture of what bad caps look like in the G5. If you see this trouble in your G5, you might be able to get this going. Kits of capacitors are available (here's the place I got some from) and If you're comfortable with electronic soldering and replacing parts on a printed circuit board, changing out the duds may be all that's needed. I've seen three of these now. On one, there was just a single bad cap that was keeping the computer from starting up. It's certainly worth looking into.

This is a common issue for G5s. The quickest solution is to open up the computer to see how much dust there is built up inside of the case. If the case has a lot of dust by the fan vent, then it cannot properly get rid of the heat that builds up from processing. Try cleaning that out.

If the computer continues to run hot, there may be some much more major issues, including ram, processor, or hard drive. Ram and hard drive issues are relatively cheap to fix, you can purchase new ram dimms or hard drives on amazon.com or crucial.com. Processors are much harder to replace and it's likely that it would be easier to purchase a new computer, rather than a new processor.

Start with the dust issue, then go from there.

Good luck!

I can only assume the hardrive is defective.

You should be able to if you are using quark license administrator as QLA uses the ethernet address commonly known as the MAC address and this is hard wired on the computer and not the hard drive to verify the license.

Not sure of your exact models so here are some solutions that hopefully some of which will apply:
