iMac G5 booting problem

[-ASH-]

Hi Guys..

My imac has started to boot with problems..

I have to press & hold the power button untill I hear the long bong (I think it's the pram reset unless someone will tell me diffrent). Then switch it off at the plug for a few minutes and then it will start..

If I then switch it off.. It will come back on ok uptill about half an hour and after that, I have to do the whole process again..

Any ideas??? Many thanks

Your power supply is most likely dead. But I would check the logicboard because this sounds like the capacitor plague. Check the logicboard for exploded or leaking capacitors. If none are found replace the power supply.

Many thanks for that..

I have checked the logic board but none are swolen so I think it could be the power supply..

Am I right in thinking that these are prone for the gpu??

Is this a problem that could be the gpu?..

Thanks

This sounds like it might be the PRAM battery. See http://manuals.info.apple.com/en_US/imacG5_allModels_BackupBattery.pdf for details on how to change it.
