    What do you mean By "Hard Time"?

    What Exactly Do you want to check? Performance? Physical Appearance?




    If you want to test performance, download Xbench at:  http://www.macupdate.com/info.php/id/100...



    open it, and Uncheck everything except CPU Test. Click Start. Then, Compare it to whatever your processor speed is supposed to be. If you are confused with the results, just copy and paste them here.

First SSE i a CPU instruction language and you can bring your tower into an Apple store and they will fix it for a fee. Try uninstalling any applications that you do not need that take more procesing power to start up.

If your cpu was bad it wouldn't turn on all the way if at all, is there actually a problem or did he just hear someone say they werent any good, if its truly a g5 its a great system im using one now, the intel ones are a waste of money, its x86 and standard pc hardware at the price of ibm's badass hardware. well hopefully you don't actually have a problem and can enjoy your mac, I've been enjoying my imac g5 for a while now, even after building a new pc, my mac from a year and a half or 2 years ago still runs the newest apps flawlessly.

The CPU is the Central Processing Unit, and is the chip that is the main "brain" of the computer.   Go under the apple menu in the Finder and choose "About this Mac," then click on "more info" near the bottom.   This will bring up all the information regarding your system, such as the hardware, printers, network, etc.  Start there and see if it reports anything being suspicious.   Macs are generally very reliable and it may just be something that a re-installation of the system software could fix, but only consider that as a last resort.   I will take this opportunity to remind you to back up everything that you consider important -- something you should be doing on a regular basis anyway.
Good luck.

What do you mean by "it's giving me a hard time?" What is the machine doing that is unusual? If it is giving you error messages, please be specific about what they are.

What kind of problem? it may be several different things....can you post more info about the specifics of the problem...just in your own words what is going wrong, when it happens, what problem it causes you, etc. Then we may be able to help.

To test the CPU, boot the computer from the CD that includes "Apple Hardware Test" and run one of the tests (I think the Extended Test is more complete and doesn't take much more time). If the test completes successfully, then it is likely that the CPU is not an issue. As mentioned before, if you have more details on the problems, try to post them here.

When you bought the G5 there should have been a Apple Hardware Test. Insert this into your drive and restart - holding the C key down... ...Eventually the application will run! :) Start off with a simple test (ignore the bit about removing Non Apple RAM) This only applied in Mac OS <9.1 GOOD LUCK

What exactly is the problem your having, a little trouble with the cpu is too general, by the way if it is an issue with the cpu it would be kernel panicing locking up, running slow, or not powering on in most cases, it could very well be a software issue or a setting that needs changed, also don't forget to repair permissions occasionaly that can save you a lot of time trouble shooting. the CPU is the centeral processing unit in other words its your IBM power5 processor, the part that does all of the actual calculations, Another thought, you may have bad ram, the issues would be similar, also make sure it has good airflow behind it these tend to run hot and will slow down a bit if the temp is really high.

You can try to boot from your recovery install media, by pressing the option key instead of the c key. Then choose hardware diagnostic, followed by selecting the arrow button. This test will be able to tell you if you have a problem.

Power mac g5 shows terrible damage in tower from leaking they swear mom board is fine but its hard to believe. are any of the other parts usable for a g3 to g5 imac or g4 powermac or emac


None of the parts are usable in any other machine.
The coolant from a liquid-cooled G5 PowerMac is toxic. If your G5 is leaking, disconnect the power cord IMMEDIATELY. Flush any skin exposed to the fluid with water for at least 15 minutes.
If you want to glove up and extract your hard drive from the machine so as to save your data, do it carefully. Other than that, my recommendation is to bag up the unit and handle it responsibly as toxic waste, using the same guidelines your area uses for antifreeze.

PowerMac G5 Mac Desktop: It will not boot...


Is this a liquid cooled G5? What CPU is it? Need as much info as possible like what where you doing last time it turned on? Have you looked inside the case? Do you hear any clicking when the power cable is connected for the first time? A lot of the last G5's were liquid cooled and a lot have leaked in the past. This small leak eventually ruins the power supply and worse yet ruins the logicboard and CPUs. If you don't know if it is liquid cooled look for a warning stamp on the bottom near front by the CPU fans (inside the case). It states to shut off if liquid is viable (something to that effect). Most times the liquid cannot be seen as it drips into the power supply on the very bottom. I would take it to Apple and have them check it out.

These are basic speakers and can be used on any computer, game system or anything other type of equipment with a stereo plug. You can plug these in the audio out jack or the headphone jack and they should work fine.

PowerMac G5 will not boot up fully, it makes it past the chime and acts like it is going to boot then restarts. Similar to when you zap the pram. It or may not eventually boot. When it does finally boot...


Do you have your G5 hooked up to a UPS? The symptoms are consistent with drive-spin-up current load temporarily overloading a marginal/failing UPS.

PowerMac G5 fan keeps running -- LOUDLY


I had the same problem... It is the logic board... You need to get it replaced. One way you could try to fix it by resetting the board there should be a little black dot behind the front two fans when you open it up. Press and hold for a few seconds... this resets the board to factory settings. The other way is replace the internal battery. and the third is to replace the logic board. $150-200

How to replace the power supply on a powermac G5


I would be very cautious doing this, if you are not an Apple tech. You can damage the connector for the G5 Processors, and render the machine un-usable.

You have to remove the RAM and Processor, then remove the two power connectors that connect from the power supply to the logic board. On the bottom, underside of the chassis, there are four screws. Remove them, then you can tilt the power supply out of the bottom of the unit.

Replacement, is just the reverse.
