It sort of looks like a RAM problem to me but ALL the SIMMS can't be
faulty
Well, they can...  When it comes to recycling, all bets are off,
particularly if nobody took anti-static precautions while handling the
parts.
I haven't had that sort of bad SIMM frequency before but it is possible 
I guess . .
...
But, for the sake of a simple thing to try, I'd try cleaning the
contacts in the RAM sockets, and the on the RAM sticks, with electrical
contact cleaner and lubricant.  Likewise, for other plug-in cards.
OK, I will try that when I am on site again in a week or so.

If you have another power supply to try, substitute it.
Yep, did that with a new (current) PS - crashed on bootup . .

People,
I have been trying to build a usable PC out of old - but previously
unused hardware (motherboards, CPUs, RAM, 80GB Seagate disks, power
supplies) - but whatever combination I use I continually get core 
dumps

I have reinstalled on numerous occasions and sometimes the PC works

for hours without a problem and then fails - but quite frequently it
fails on bootup!  I have tried with 2G RAM but that had problems so I
went back to 1G thinking that one SIMM might be faulty but no
combination works for any reasonable length of time.
Which CPU are you using? Unless it's a hardware defect somewhere, I'm
inclined to believe you could be trying to run an incompatible kernel.
Hmmm . . that MB is for Socket478 processors and I definitely installed 
the 32 bit F20 (LiveCD install) - how could it be incompatible?  Would 
F20 64bit even install?

Yes, I think a HW list along with the SW being tried would likely prove
helpful here.
OK, that will have to wait till I can get back on site again too - of 
course my remote ssh connection doesn't work now because of another 
crash - I'm surprised it lasted as long as it did!

Thanks people - more info to come later!
