I have a Quadra 840AV that I found one day on my way home from work. I
brought it home, hooked it up to my monitor and keyboard, and found it
worked just fine. I decided to do a few upgrades on it by adding memory
and filling the vram slots. Since then I can not get it to start up
again. When I try to start it, I get no chime, just a blank gray screen
with the cursor in the upper left hand corner.
Here's a list of what I've tried to remedy the problem with no results:
I removed all of the upgrades I added except for one simm that I know is
good. No go.
I tried starting up from a system floppy. No go. Just the blank gray
screen with the cursor that won't move.
I tried starting up from an original Quadra 840AV system CD. See above.
I replaced the PRAM battery with a brand new one. No good even after I
have left it without a battery overnight.
I tried zapping the PRAM.
I have checked all of my cables numerous times, and all seem to be
seated solidly.
I have no external SCSI items connected to the machine.

Right now my biggest fear is that I may have damaged the motherboard
with static, even though I was very careful.
But I must admit I had one hell of a time getting everything aligned
properly each time I put the motherboard back. Is this something other
Quadra 840AV owners have experienced? Is there anything I can do to fix
it?


If you are stuck on a gray screen then the startup disk is not an 
issue, it's not getting that far.Best guess is that some of the 
VRAM is either mis-seated, wrong or bad.  Also possibly the RAM is 
also in similar straights.

Start by removing the RAM you added.  If that doesn't help then 
remove the added VRAM.

Sounds like something I had going on with one of mine... even tried it with 
one known good memory module that turned out to be not-so-good, and was 
causing the problem (though it would sit there for half an hour, finally 
give the not-quite-chimes-crash, and I could reboot and use it...)

Try one different SIMM. Remove the VRAM.  Make sure it's all seated 
completely. And of course double check all cable connections.
