Perhaps yours is still covered. You have damaged RAM, and possibly other problems. Not sure if that is the issue. If this answer is acceptable please remember to return and mark it. A single beep indicates no RAM is installed, which indicates the RAM modules are not getting enough power or have become corrupted to the extent that the system does not register them as being present. The procedure for resetting the SMC depends on the specific system you have, but Apple has a knowledgebase document that covers how to do this on various systems.

Definitely a hardware error. The only question is, is it bad RAM, or a bad logic board? Reset the SMC. After major hardware changes this is always a good idea: Depending on which iMac G5, this may help: Any chance the logic board you got is in fact bad?

Ebay, or other questionable source? I can't imagine there are many good ones out there for sale, given the demand. Apple charges so much for new replacements, I would recommend a differnt machine instead. The Intel Imacs are so much better, it isn't even close When there is no ram in the system it will beep only once.

Does this help? On the up side, Apple had a three year extended warranty on G5 iMacs. Perhaps yours is still covered.

The procedure for resetting the SMC depends on the specific system you have, but Apple has a knowledgebase document that covers how to do this on various systems. Beeps and flashing LEDs If you start up your Mac and instead of hearing the boot chimes you get a single loud beep or series of beeps, then this indicates a hardware failure either in the processor or in the RAM. A single beep indicates no RAM is installed, which indicates the RAM modules are not getting enough power or have become corrupted to the extent that the system does not register them as being present.

If you hear two beeps, then this indicates you have RAM installed but it is determined to be incompatible with your system. This issue is likely the case after you have upgraded your RAM with modules that are too slow for your system's RAM bus. If you hear three beeps, then the system is telling you the RAM is recognized but for some reason it cannot access the memory banks, which is likely the result of corruption from static discharges or factory faults in the memory chips. In these situations, your best bet is to replace the RAM.

If you experience more beeps than a series of three when powering on your system, then this indicates a problem with your computer's ROM or processor, and it will need to be taken in for servicing. In addition to beeps, the system may flash its power LED in various patterns to indicate similar issues. No activity after boot chimes A final issue if you hear nothing after the power is turned on is faults in the system's ability to load parameter RAM variables, which are hardware settings the system uses before it loads the system software.

While PRAM errors usually result in odd setting being persistent after bootup, on rare occasion a fault in the PRAM may result in a hang when the system tries to access it, and clearing the PRAM is the only way to get around this issue. To do this, restart your system with the Option-Command-P-R keys all held down at once, and release them after you hear the system reset and sound the boot chimes again. Have a fix?
