SOURCE: G4 wont boot up
you poor little mac is hanging there eh, its having a kernel panic. which gives you the impression the motherboard has packed in. My G4 suddenly began doing this overnight, fine one day dead the next. Anyway i took it to a repair centre who said it was the board and couldnt get me one due to it being obsolete so to ebay i went. In went the new board and yeehah.. the same bloody thing occured. So after that i found the only way of it booting up was to open the case slightly just to get my hand in and push down on the processor ( not applying the pressure onto the board, but as though your trying to push the processor down toward where the drives are housed), This seemed to work but sometimes it would pop up the old restart you computer or the little wheel would just spin till i was an old man. so i removed the processor and sat for an hour with a magnifying glass and moved the pins closer together on the board. refitted and its been going strong ever since, Wierd i know, my cousin has been a mac fan for years and satin disbelief when i showed him how i booted it up. I have a G5 but just doesnt have the character my G4 has.

you might need to check the usb connections for the keyboard and mouse. and see if they are correctly connected, also to clean the connections with a q-tip from time to time. Also you might want to switch to another usb port. to narrow down the issue. Because if say you change to another port and it still persists, even when running a usb hub with external power, and even a external firewire hub with usb connection then the issue would be the com board for the usb and firewire. and hopefully the G5's usb, firewire ports are on a separate board that is then ribbon wired to the main board. because if its just ports ribboned to the main board you will need to get a new logic board. and that is not cheap. unless you still have your applecare. then just take it in to get replaced.
