I have a Linux server that is failing. It hangs or reboots itself randomly. I'm pretty sure I've eliminated disk errors as the cause because it fails even when booting Knoppix. I've also swapped memory around and given it all a good clean without any improvement.
Everything else is onboard (SCSI, IDE, VGA) so I think I'm left with the motherboard or a CPU (dual) causing the problem.
I'd like to run a hardware diagnostic tool on it. Preferably a bootable one. The only one I know is PC Check which is a few hundred pounds - and I'll get that if I have to - but I was wondering if there were any open source solutions out there?
Thanks for any info.
