Unhappy G4 Problems - Power Supply???

Greetings fellow Canadian Mac users!!! Glad to have found this site.

I recently was given a G4 Tower 400 with AGP graphics. I am using a G3 tower and have three drives in it, the one the computer was shipped with and a 32 GB Maxtor and a 120 GB Western Digital. I wanted to use the maxtor and WD in the G4 but the first problem was the G4 only had one other power supply. I got a power splitter cable and then installed these drives in the G4 using a Sonnet Tempo Ultra ATA 66 PCI card (out of my G3) to connect the additional hard drives.

I should tell you the G4 ran fine before I installed the additional drives. After the install I booted up the computer and everything seemed to be normal however the computer froze up shortly after I started using it. I rebooted and it hung up loading the Finder. I rebooted again and nothing. I removed the hard drives and PCI card and rebooted. Totally dead.

The machine does nothing now. Doesn't have a startup chime and the monitor stays black. Don't even hear the hard drive spin up. The LED on the front doesn't even stay lite. About the only thing that seems to work is the Zip drive. You can insert and eject a disk normally.

I've checked Apples tech support and did all the things they said with no difference. I'm thinking the power supply got cooked or something. Don't really understand why as my G3 just cruises along, although I think its power supply is better. Why would Apple put in additional drive carriers if you can't use them??

Any suggestions to get this G4 going would be greatly appreciated. Otherwise it's is going for recycle.

Thanks

Question. Have you pressed the CUDA reset button yet?

I work on the dark side because the pay is better than what I could get the Apple world. Sad but true

Yes. That was part of the Apple Tech Support process.

There's a bigger chance that your logic board is defective over your power supply. The only way to tell for sure is the have the voltages properly checked and tested on key points on the power supply. If you can't do it yourself, bring it in, pay the $50 diagnostic fee (or whatever it may be.. usually close to that figure), and get an exact answer. It's your best bet.
