hardware troubleshooting

I have an older PC (vintage ?), P3 667Mhz, 768MB, 2940UWP SCSI

it was my old desktop, and, it always worked 24x7

I suddenly developed a reboot loop: it start re-booting, then rebooting
once the system starts loading.

as it has three 256 SIMMs, I've tried one by one with just one of the
three SIMMs installed, regadrless on which single SIMM is installed, same
reboot loop

I've run Memtest 4.1 on a single SIMM, after 20+ hours and about 20
passess, no errors

if I try to boot Knoppix from IDE CD, it boot to the first screen, when I
hit enter to load Knoppix, shortly after it starts loading, it reboots

clearly it's not worth fixing a P3, but, I'm curious what's failed in
this, any clues ?

- SCSI HD boot (3 different boot partitions) reboot;
- IDE CD Knoppix boot, reboot;
- IDE CD MemText86 tests RAM OK
