I recently purchased a B&W G3/400 256 ram, zip, 12 gig HD, original CD & 
ultra SCSI PCI card running OS 9.2.2 to replace my tried and true Starmax
5500/200 OS 8.6.  Since the purchase I added - one at at time - an 80 gig
Seagate HD, USB floppy, Pioneer DVR106 CD drive and another 256 ram.  I also
tried an Xlr8 G4/500-533 upgrade but it was DOA and I returned it for
replacement.  I ran into a couple of start-up issues during the upgrades
that I thought I resolved but now I'm not sure.

Prior to the 80 HD install the System Profiler showed 256 ram.  Immediately
after the HD install SP showed 128.  Assuming I bumped one of the chips
during the install, I moved both 128 chips from the 2 inside slots to the
two outside slots. The SP showed 256 and continued to show it until I
installed the 256 chip a week later (in one of the two vacant inside slots).
The boot up after the chip install went like this - computer fan starts up,
CD light cycles on then off, HD "spins up" briefly - 1 second, 2 at the most
- then nothing.  The computer sat with power on, meanwhile the screen hadn't
done anything.  It was just black.  Several retries resulted in the same
results so I moved the 256 chip to the other vacant inside slot and
rebooted.  Everything booted fine and SP showed 512 ram.  I assumed I had a
bad #2 slot.

The same start-up problem - exactly the same - occurred when I replaced the
G3 CPU with the G4 upgrade.  Once the G3 was put back in start-up was
normal.  Since both problems were resolved when I "undid" something, I
assumed that was the cause of the problem.  However, last night I started
the computer and it did almost the same start-up sequence except this time,
the start-up made it to a gray screen with the pointer in the upper left
corner before the boot stopped.  A reboot went off without a hitch.  In all
the above mentioned cases the computer did not go through the "fix" that
occurs when the computer crashes.  Is there a deeper problem that I should
address or are the boot issues related to the upgrades I've been making?
Sorry for this long post but I want to try Panther once I have the hardware
upgrades completed and want to eliminate all other problems before doing so.
