PowerPC :: G4 PowerMac That Will Not Boot Up?

Nov 2, 2007

I have a G4 PowerMac that will not boot up. I power up the computer and it stalls on a grey screen with text prompting me to type <<boot>> if you wish to continue...or something like that. Does anyone have any advice on how I might troubleshoot this? The computer was working fine for a few days before this occured. It has been unused and sitting is storage for a while.

Aug 1, 2010

There is a Powermac G5 available in my area for $450. Its a dual core 2.3 and a nvidia GeForce 6600 and he is including a 20 inch ACD. I don't know if its a great deal, but I think it would be great, because I could build something wild in that case later.

PowerPC :: Overclocking Possible For PowerMac G4 1.42 DP?

Nov 17, 2010

I recently bought a PowerMac G4 1.42GHz Dual Processor. It has 2 gigs of RAM on it. It was a fair deal I think. The "thing" is still looking like new and shiny. Even the insides are still tidy and intact. My question is, would I still be able to pump more juice from this beast. It still run fast comparable to some decent windoze box. Up to how much processor can i be able to squeeze out the CPU and if possible, how to?

PowerPC :: G$ PowerMac Shuts Itself Off?

Apr 18, 2007

I have a G4 Power Mac. It's the "digital audio" model that has been upgraded with a 1.2Ghz G4 processor. It works well except for one thing. It shuts down randomly and suddenly. Then after 5 or 10 minutes it turns itself back on, reboots and runs fine. (It is set to re-boot after a power failure.)I suspect what is happing is the power supply is turnning itself off due to some kind of a thermal, self protection switch. The fan seems to work but the PS gets warm.What's the cure? Replace the power supply? If so where to get a new(er) one?

PowerPC :: PowerMac G5 Not Booting?

Jun 11, 2008

I have a PowerMac G5 dual 1.8ghz running leopard. It worked flawlessly since the day I bought it.

Then as of last week whenever I booted the computer I would get the gray screen with a black box saying to reboot the computer (in 5 different languages). I would reboot the computer. Same screen.

Is there some way to check what is wrong? Is this typically a hardware issue or an operating system?

PowerPC :: Powermac G4 Not Booting Up?

Sep 19, 2008

I was installing Tiger using FireWire from my Powermac G4 and it was nearly done when my Powerbook (target) died due to lack of battery... When the Powermac was rebooted, I get only a question mark and flashing smile.

I tried to test the C and T keys holding them down during boot up but only get the smiley face every single time... I even disconnected the secondary drive to no avail.

Please could you help me with this problem that i've got with my Powermac G5.

Tried the following..

Is there anything else i can do. It's a really good machine so i hope it's not needing a Logic Board repair!

PowerPC :: Powermac G4 Will Not Power On

Jan 27, 2009

Currently it is almost entirely unresponsive. I came to wake it from sleep a few days ago and it refused to wake. It is totally unresponsive to the power button on the Apple Cinema display and when the power button on the front of the tower is used the button lights up blue and then goes out. There is no fan activity or other sign of life. There is no burned oder or evidence of anything charred.It is a dual 1.42 MDD FW800 machine with AGP graphics. Model: M8570So far I have:

-Removed and reseated the graphics card, RAM and other PCI cards.
-Removed battery and let it sit unplugged over night.
-Performed PMU reset. (once)

At this point I have come to believe the power supply needs to be replaced. it is model: 614-0224 (360w). After looking online they are stupidly expensive, from $180 to over $500 each. I will be ordering a new MB (PRAM?) battery (Saft 3.6v LS14250C) and replacing that as well.

Questions:
- Have I missed anything here? Is there any other explanation or method of troubleshooting I should try?
- Is there any cheaper source for the power supplies? Why are they so absurdly expensive? Does anyone here want to give me a sweetheart deal on one?
- Can anyone recommend a source for the LS14250C battery locally in Manhattan? Radioshack has it as an online only item and wants $15 for it.

PowerPC :: SATA Controller For PowerMac G4

Nov 22, 2010

I have a PowerMac G4 (MDD 2003, I believe) that I use as my home media server for my Apple TV. Currently I have a 14+14GB boot RAID and 75+75GB storage RAID, using old PATA drives, of course. This is working great and is pretty well performing so far, but I'm going to run out of space eventually since I'm a packrat. I'm thinking that this Christmas will be a good time to renovate this machine, so here's the question MacRumors: What's the best SATA controller for my machine? PS: It's a dual 1.25GHz PowerMac 3,6. In MacTracker, this matches 3 different machines. Is there a way to find out which one this truly is?

PowerPC :: How Can I Speed Up The PowerMac G5 Fans?

Jan 4, 2011

My PowerMac G5 fans hardly ever speed up. I mean they certainly never go full speed or ever close how they sometimes behave on start up. I never get the jet speed noise. Even when I am rendering a movie in FCP, I hardly hear the fans. Right now on idle, iStat pro reports CPU A being 58C and CPU B being 56C. Yet, the fans are still only 400RPM both CPUS Intake/Outake.

PowerPC :: Powermac G5 SP 1.8 Roaring Fans

Oct 26, 2006

I have a strange problem with the powermac G5 1.8 SP, yes the one with the hardware bug. It was my first mac, what a dissapointment. The bug was partly solved with the firmware upgrade, but after that it still behaved strangely. The fans suddenly go up to maximum speed every hour, then quikcly return to normal. There still have been lockup's / beachballing with USB, and overall slow performance.Now I am running the latest mac osx Tiger version, about a few weeks ago, the fans start revving up almost to maximum, all the time, regardless of cpu load. The cpu temperature reads about 60...65 degrees centigrade when idling (minimum cpu load), cpu setting is already on "reduced speed". After switching-on, cpu temperature is already 60 degrees centigrade. The cpu heatsink is stonecold, as is the exhaust airflow. The cpu 2 fans roar like mad and keep revving up and down. When I remove the plastic transparent cover, the photocell is activated and a red LED comes on, now the fans immediately return to normal speed. Anybody else had similar problems wit the powermac G5 SP 1.8Ghz ?

PowerPC :: PowerMac G5 Dual-Core/Add Another CPU?

Nov 18, 2006

I've got a PowerMac G5 dual-core 2GHz box. Can I add another dual core CPU to get a quad-CPU system?

Forgive me for not wanting to open the case and look for myself, but it lives in a little hole that is hard to get out of b/c of all the cables and stuff... just wondering if anyone knows off the top of their head if the motherboard has another slot...

PowerPC :: Graphics Card Changes In Powermac G5 2.0 DP?

Jan 15, 2007

Really wanted to update my Powermac this year to a MacPro but as I'm getting married it's going to be an expensive year so I've decided to upgrade the G5 2.0 DP I already have.At the moment the kit I have is pretty good in that I have 1.5 gig of memory and 250gig of hard drive space but I'm open to suggestions.The G5 I have is the PCI version so I'm a bit limited as to what I can upgrade but the main area I'm looking at is with the graphics card. I had BTO the ATI 9650 256meg card but I'm looking for something better. I've just started to get into "World Of Warcraft" and would like the best graphics card that is value for money.

PowerPC :: Mac Mini C2D Vs PowerMac G5 Dual 2.0

Jan 1, 2008

I'm kicking around the idea of switching my Rev. A PowerMac G5 Dual 2.0 for a Mac Mini Core 2 Duo 2 Ghz with 2 Gigs of RAM. I'm wondering if I would take a big performance hit with the switch to this machine when compared to my current workstation (most likely not, but hey I ask anyways). I am looking for something with a small footprint that's quite and basically is not a furnace with computing features inside that sucks power like a maniac. It's worth mention that I am on a budget as well(Macs here in Argentina are expensive as hell). As it is right now, if I do a feature to feature comparison, I would be getting DL DVD burning, Airport, and Bluetooth, something that my PowerMac G5 is lacking.

Its worth noting that the PowerMac has 1 Gig of RAM, the stock Radeon 9600 with 64 MB of RAM, but does have a 250 Gig HD. I regurlarly use Photoshop CS3 (working mostly with A3 sized files @ 300/600 DPI), Illustrator, in Design, Dreamweaver, some Flash. Of course the run of the mill, Web browsing/email checking along with IMing and iTunes activities. So what you guys think? You think a trade of my ol' faithful PowerMac from 2003/2004 to a top of the line mac mini would be a good idea?

PowerPC :: PowerMac Fan Speed Increase After 10.5.2

Feb 15, 2008

Anyone else notice a 1000rpm CPU fan speed increase on their G5 after the last round of system updates? My CPU's used to idle at ~120*f with a fan speed of 500rpm. After the 10.5.2 update they idle at ~89*f and 1500rpm. There is no perceptible noise change and I didn't even notice the change until I saw the cold CPU temperatures. I'm not worried about it, I'm just wondering if I'm alone or this is one of the system level .2 changes not massively publicized.

PowerPC :: G5 Powermac Overheating And Switching Off / Fix This?

Oct 14, 2008

I have a G5 2.7ghz powermac. Recently it began switching itself off at start up. If it did boot up - it would only last for a few minutes that it would freeze.
I clean out the dust from the inside and even took the cpu cover off - none of it has made any difference. I have also replaced the lithium battery. Has anybody else experience this?

PowerPC :: Just Got A Free Powermac 466 128 Ram 20GB HD

Apr 21, 2009

thought id say that i was given a free powermac 466/128 ram/20GB HD that seems to be working pretty well. However, revisiting the old mac design classics has led me to look into getting another model for basic internet/email/itunes in another room in my house. Someone locally is offering their G4 933/1.25 GB Ram/ 240 GB HD model (im guessing from 2002), alongside their 17" apple display for a total between ?220-250.Is this worth it? are there any problems that i should look out for.
