Question

PowerMac G4 will not wake from sleep correctly, or shut down?

hi all,

I have a quicksilver 2001 g4, dual 800mhz running a tripleboot of leopar, tiger, and OS 9. anyways, If I allow the cmputer to sleep, it will freeze up and/or display weird colored objects on the screen. Also, when I shut down the computer it will not turn off. Either I get the SPOD, or the screen blacks out (like it should) but the rest of the machine is still on, and i have to turn it off by hand.

I just put in a new PRAM battery last night, zapped it, and it still does it. Any idea?

-Thanks in advanced

PowerMac, Mac OS X (10.5.8), Dual 800mhz QuickSilver,160gb,1.5gb

Sounds like it could be a bad graphics card or main logic board.

Is there a real desire to keep a 10 year old Mac in working order? At this point, it might be worth an upgrade.

I just bought this about a month ago, it was used for about a month before that. its mint. I dont have the money for even a G5. Everything else seems okay, and I was actually wondering if it was the graphics card but the AHT CD found no problems.

It was used for one month over the course of 10 years? That seems unusual.

If it's really worth making it work, it can be run without sleep or shutdown.

Do you have any third party USB or graphic cards installed ? In the past these have caused problems with these machines,also an external drive can do the same thing. I suspect your triple boot setup is at fault as the hack need to install Leopard might have messed things up. You might want to try a small program called "Applejack" and see it that helps.

Does it have any PCI cards in it? What all USB or FW devices are connected?

As a matter of fact I have a USB 2.0 card isntalled that doesn't work right and i was going to replace. I have a few External Drives I use from time to time. But the computer has on board USB 1.1, so a 2.0 card is a necessary. There's also the factery Geforce 3 that came with it, but thats an AGP card. I use TDM via FW from my iBook G4 also every now and then.

Pull the card out, might very well be it, also, I assume the FW cable you use for TDM isn't plugged in when trying this?

I usually leave the FW always plugged in on the PM end, it sits under the desk as the iBook is ontop. but i always remove all cables when opening the mac if thats what you meant.

Also, if removing the card were to fix this problem, would that be a bad card? or would the problem return if I bought a new card?
