i have a blue G3 with a 900Mhz proc, and I just put in a new 60Gb hard drive. Im trying to boot from the OSX install CD and every time I try it gets to the beginning grey apple screen, the little circling whatchamadoo comes up just below the apple- spins less than a full spin, then the system hangs. i tried command-option-p-r to flush the PRAM, then tried holding shift on boot, and as im typing this post, its actually just showed me an error message.

What does all this mean?
 
It's a kernel panic -- something's wrong that's preventing the system from booting normally.

I would suspect either the hard drive or processor first -- what do you have the hard drive jumpered as? Master? Slave? It should be master, if it's the only hard drive in there (and it should be the only one in there if you've got a revision 1 B&W machine).

Try swapping the processor back out for your original and see if that helps. If it does, install with the old processor, then pop in the new one and see if it'll boot.
 
It means you are encountering a kernel panic, most likely as a result of a hardware problem/conflict in your system. There are any number of possible causes, but the most obvious suspect would be your aftermarket CPU upgrade. Some things you might try, in the order I would try them, are:
  1. Remove all external USB and Firewire devices except the keyboard and mouse. That includes USB hubs. You can plug them all back in after the installation.
  2. Remove any third party aftermarket PCI cards. If you have upgraded the video card, put the original back in. Most of these can be put back after a successful install
  3. Selectively remove RAM modules, just don't go below 128 MB.
  4. Remove the aftermarket CPU and put the original CPU back in. If this solves the problem contact the manufacturer and/or take a look at XLR8YourMac user reports database for suggested work arounds.
Good Luck!
 
well thanks for your replies, the only aftermarket thing in the computer was the processor, tried putting the original one back in- but now I think it's dead (just guessing, but i dont think smoke coming from the motherboard is a good thing) and neither processor works. system powers on, but nothing on the monitor, no chime- just a really bad smell
 
Ouch. That does sound bad, and I think you may end up with more problems than you had in the first place...

Simply replacing a processor should NEVER cause the motherboard to overheat like that. I'm sure the 900MHz processor came with a new jumper block, right? Did you set the motherboard bus ratio jumpers back to the correct multiplier for your old processor when you put it back in?
