g4 cube startup issues help!

[madmann]

I had a bad hd and replaced it 2 weeks ago bad sectors.

now it has stopped starting up

1 it chimes

2 i get a gray screen no pin wheel

3 nothing happens.

i have tried booting off tech tools cd but no luck. same as above

this issue happened 2 times and the machine sat for some time and started up

now i get as described above

i am thinking

cpu over heat.

bad cpu

bad memory

bad mobo

would the chime eliminate any of the previous hard ware?

I'd take it back to when you replaced the hard disk - did you set master/slave on the new drive? The fact that it's chiming, booting to a grey screen suggests all is good - so I'd investigate your IDE devices to make sure the right master/slave combination is all set. Whilst you're in there, by all means reset the CPU card, RAM, graphics card - etc.

Can you get into Open Firmware at all (command + option + O + F at chime)

For shits and giggles, take the hard drive out and just boot from an os x disk, see what happens.

Thats how I've figured out bad hard drives and such. Of course, a full size G4 tower is a little easier to just take hard drives in and out from.

well I know the master slave jumpers are ok. the computer worker great for several weeks after the new hd. I reformateded and installed 10.4 clean and then ran tech tools to check everything it could. I will pull the drive and try to boot from the cd.

Cubes are fun machines.

When you put it all back together, was everything nice and tight and all cables run in their appropriate channels? Due to their compact design, things can kind of shift a bit and lose a bit of contact. The cage the gear sits in is a good design, but seems structurally weak to me.
