Power Mac G5 Support

You could try resetting the PRAM:

Resetting your Mac's PRAM and NVRAM

Did it work the first time? If, so, maybe the PRAM battery got loosened during the move, or maybe it needs a new one?

Sounds like it might be a finicky monitor cable or video card. Is the video card seated snugly? Does the monitor cable make a good connection with the video port? Are there any bent pins or anything of that nature with the monitor cable or video port?

Have you tried resetting the Cuda/PMU/SMU?

Resetting Cuda/PMU on Power Mac G5, Power Mac G4, Power Macintosh G3

How to reset the SMU on a Power Mac G5 (Late 2004) or Power Mac G5 (Late 2005)

It's not liquid cooled, what do you mean by bad caps?

I think he means bad capacitors. There was a problem with bad capacitors a few years ago, that I believe, affected most of the computer industry. Sorry to hear that the seller is not being responsive. Was email involved in this transaction with the seller? If, so, I believe that the U.S. Postal Service will help you with this as it's considered mail fraud.

I don't think the bad caps extended as far as the power macs but I could be wrong. Okay so here's what I want you to do

First check the video card and see If it's the stock or a compatible card. Examin the card for any color distortion due to excess heat or faulty componets. If possible put in another card and see if that solves your problem

Check all connections inside the power Mac and make sure everything is seated properly. Check

CPUs
Ram
Hard drive and optical drive connectors
Any expansion cards
The video card

Try booting it up, if that's a no go

Try unplugging the hard drive and optical drives and see if that will let it boot, if nothing

Remove the PRAM battery and verify it's village with a multimeter and reinstall it (make sure you put it in the right way ie positive to positive) reset the pram again and try, if no go

If worst comes to worst gut the motherboard,CPUs, and ram. Sell them and replace them with pc parts and have a sweet looking hackintosh.


Since you went to this persons house I would show back up and demand your money back. Don't take no for a answer.

And when you refuse to leave and the seller calls the police, make sure to make some threats?

You could always sue the seller in small claims court. It's free in some states and cheap in many others. Ask for the amount paid, plus court fees, and damages which include your time. If/when the seller fails to show up for court he automatically loses and the judge rules in your honor.

If he calls the cops on you then you know something is wrong and he burned you so wait there for the cops and explain your situation. You would be surprised how many of them hate people that scam on craigslist. It's a big thing out here in oregon

Small claims court is a joke. More waste of your time and money. What if the person is unemployed? Can't squeeze water from a rock
