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.

I can't do screen captures of course but I have taken a photo of the most recent crash and I can see:
- at 21s:
search_binary_handler+ . . . do_execve_common+ . . . SyS_execve . . . Code: . . . string of two digit hex numbers EIP: . . . CR2: . . . --[ end trace . . . firewalld[461]: segfault at . . . . . .
- at 3308s:

I can put this 2.3M photo somewhere if it is of use for anyone to look at? Any ideas what the problem(s) might be? It sort of looks like a RAM problem to me but ALL the SIMMS can't be faulty . .
Thanks,
Phil.

Well, they can... When it comes to recycling, all bets are off, particularly if nobody took anti-static precautions while handling the parts.
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.
If you have another power supply to try, substitute it.

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.

Yes, I think a HW list along with the SW being tried would likely prove helpful here.

When I have a flaky system, I fire up memtest86+ and let it rip for 12 to 24 hours. I sometimes finds an error. If the memory passes, I no longer have niggling doubts.
I've found power supplies can be a source of instability. But you've tested that.
Try a really old distro to see it is stable. Old paths in new distros don't get tested much.
There are the old tricks of passing kernel parameters to turn off certain tricky bits like ACPI. Video is sometimes a problem too.
Your hardware is worth very little at this point. If you value your time, you might consider giving up. But I understand the joys of scrounging and of problem solving.

They could be. memtest86+ to find out. Another possibility is they're the wrong SIMMs for the hardware, i.e. wrong timing or voltage. There might be BIOS settings for adjusting this.

I like Puppy linux as a place to start. Probably Wary.
