I have a last model G5 with dual 2.5ghz and 4.5 gigs of ram. It also has the 7800gt video card.After I start it up it runs for about 15 minutes and then the display goes blank and the system fans go full out. I've tried resetting the PRAM, PMU, VRAM, all of those things...the last thing I have is the video card to test.Also the power supply was just replaced by a Apple Repair Center under extended warranty.

I just upgraded from a Powermac G3 (1st rev.) to a Powermac G4 DP 1.25 ghz... so much faster! Any other fans here? Any cool stories to tell about it?
View 17 Replies View RelatedMy 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.
View 4 Replies View RelatedI 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 ?
View 12 Replies View RelatedMy CPU fans for proc.A are near-constantly capped at 300rpm(system minimum), no matter how damn fast the B-fans spin to compensate.I have: Kept it clean inside. Kept CPU settings on Highest, as usual, but tried Reduced/Auto Repaired permissions Reset the PRAM Reset the PMU Booted into single-user mode Reinstalled Leopard
Obtained & ran Service Diagnostic CD and passed all tests Re-calibrated the CPU's only to notice the speeds now hover around 400rpm now What more can I possibly try? I don't believe a re-seating of CPU's is in order. They work great. All my fans & temperature sensors passed their diagnostics tests, too.I am very irritated by the noise of 2/4 fans overcompensating and getting very loud, from 2000rm-4000rpm, and hey, my Mac is screwed up, and I really need to fix this.
CPU cooling fans are running at strange different speeds. Powermac G5 early 2005, dual G5 (not dual core).This is at idle:CPU A 60 degree Intake 300rpm Exhaust 300rpmCPU B 63 degrees Intake 1125rpm Exhaust 1100rpm! I have not noticed this before. They usually remain identical.

View 2 Replies View RelatedI've cleaned all my components except the HDD bay fans on my G5 Powermac. I've searched google about 5 pages deep and no luck. I have the service manual but it doesn't show how to remove those fans either. Anyone know of a link that shows how to remove them? I'm very good at taking stuff apart but I just can't seem to take this fan assembly apart. Maybe it's my kryptonite?

View 2 Replies View RelatedWe have a PowerMac G5 machine which won't boot at all. you can hear it turn on and everything (including the chime at bootup) but you won't see anything show up on the display.
Also after several minutes, you will hear a very loud noise come from the machine, the fan you can tell is extremely loud. Not knowing this stuff very well as i'm more a PC tech than Mac, what are some options to troubleshot?
My 2002 iBook G3 notebook with OS X3.9 started acting up on me finally! 2 days ago I turned it on and it sounds like it is starting up normally, but when the screen comes on, it just stays lit up and black - I tried everything, from trying to adjust the brightness, to restarting it a zillion times to completely draining the battery and then restarting it again, nothing seems to work right! I thought it may be the backlight, but then the light does come on, and stays on - the apple logo on the back stays lit up even when I close the notebook.
View 1 Replies View RelatedAfter packing away my little brothers sawtooth 400Mhz with 384mb RAM and an 8Mb ATI AGP graphics card and then unpacking it I've been having a problem. When starting the computer up the screen shows nothing at all I have tested to see if the screen is broken and it seems to be functional. I think the card itself might be broken? BTW, I'm using the VGA slot and not the DVI slot on the back. I have also removed and cleaned the card just incase that might've been the problem.

View 7 Replies View RelatedI just bought an LG 32" LCD TV (model 32LB9DB). It has 3 HDMI connections on the back, so, I bought a DVI-HDMI cable and connected that to my PowerMac's DVI port (PowerPC G4, 1.75 GB Ram, ATI Radeon 9000 Pro video card) and then to the TV's HDMI port. I can see my desktop and everything, but, the image quality is very poor no matter what resolution I choose. It looks like the digital signal is being converted to an analog signal before being displayed, so, text is blurry and the overall image looks very poor, not at all like a computer monitor. It looks like a computer image displayed on an analog TV.
I thought that if the TV had digital video input, I would get a 1:1 pixel resolution when attached to my computer, but, I guess not. Am I doing something wrong with the setup? I've already looked at all the TV's settings, and tried lots of different ones, but, the image quality doesn't improve. Here's the detail about my Display:
ATI Radeon 9000 Pro:
Chipset Model:ATY,RV250
Type:Display
Bus:AGP
Slot:SLOT-1
VRAM (Total):64 MB
Vendor:ATI (0x1002)
Device ID:0x4966.........................
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.
View 6 Replies View RelatedSo, I think my PM G4 finally died. I had been using it as a media annex (not center) in my living room since my 22" Apple Cinema Display still works fine. Now I'm stuck with a 22" monitor that can't be connected to anything. I've been looking into what can be done. Based on an Apple Support Document, there is a M8661LL/A part called "Apple DVI to ADC Adapter" that I think will do the trick. If I get it, I should be able to hook my PowerBook G4 up to it, right? If so, the next task is to find the sucker. searching online for the part number didn't yield much, but I did find a nearly identical product number, the M8661LL/B on Amazon for $90 (yikes!!). The only difference is the suffix letter. But I don't know enough about this to really know if it'd work.
View 2 Replies View RelatedI 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?
View 12 Replies View RelatedI 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?

View 2 Replies View RelatedI 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?
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.
Spec is
Dual G5
2gb ram
I'm trying to boot from the Mac OS cd (tried 10.4 that it came with and 10.5) and both get to the grey screen with the Apple Logo and that's as far as it gets. No spinning loading wheel.
Tried the following..
PRAM reset
Swapping Ram out
Is there anything else i can do. It's a really good machine so i hope it's not needing a Logic Board repair!
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.

Just like the title says I wanted to know what is the max and/or average dB value / noise level for the cooling fans of the new MacBook Pro with Retina Display.I saw that there are asymmetrically spaced impeller blades to reduce noise, but also it says "reducing tonal impact". So there seems to be a noticeable noise level? I work in very quiet locations and have good ears, so I wondered if I better don't get one of these. I'm currently using an iMac 27" and once the hard disks are running at full speed after starting up I cannot hear anything.

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?
