Why are both of my Pismos refusing to start! Help!

Anyone who has been following the soap opera that is my attempt to get my first Pismo to start, will now find that there is a new twist.

The spare machine which was working fine yesterday, has now developed the same problem as the first machine! (I had put the drive from the first Pismo into this second machine on Sunday and got it to fire up just fine).

All I get at startup is the screen lighting up, that is all. I have removed the suspect hard drive and have been able to fire up the machine using a Tiger installation disk.

Surely both drives couldn't have failed?! I thought that I was getting somewhere with this problem but I am running out of options.

Could this be a power issue?

Is there anything that people could suggest? I'm afraid I'm getting a bit exasperated with it now.

Did you run "Disk Utilities" from the Tiger disk on the hard drive? If not, do so.

If that fixes the problem (which I don't think it will) you're good.

Next put the working hard drive back in and see if it will boot. If so, then you are good. Take the old hard drive (which will not run in either machine and put it in the trash.

You just installed the drive in the second machine. I would recheck the CPU card is firmly and properly in place as my first step, and would also disconnect the PRAM battery. One thing I would do is concentrate on one machine until I had it running well and then look at the other. Good luck. Ralph

I got the original machine to boot from a Tiger install disk but received a message advising that there were 'missing packages' when I tried to verify permissions. The other computer would not get beyond the Apple logo at startup. I tried using a Jaguar install disk on the original computer as the hard drive was loaded with Jaguar but I could not get the computer to fire up as it had before. Inconsistent! Mal.

On Saturday I am going to try and install the 'new' hard drive on one or possibly even both machines and see what happens. The supplier of the hard drive has suggested that the problem could be caused by a 'disc controller' fault (a chip on the main logic board). Has anyone else encountered this problem? I take it that iFixt have a guide for replacing the main logic board? I will let you know how I get on. Fingers croseed! Mal.

Just finished working on both computers. No joy. I fitted the 'new' drive in both of them and I am still getting the same result (the screen lights up and that is as far as it gets). I'm guessing that it must be the logic board. Any thoughts from anyone else? Mal
