Actually, the PSU in the server too seems to be fine. It had been powered off for about 48 hours, and what passes for summer here (low 20s, no breeze) finished three or four hours ago - I had to shut the window. It was silent when I turned the PSU on, and appeared to start (fans for case, cpu, psu all spinning). This is plugged directly into the mains. Back of case fan (at rear) and underside of cpu fan had a lot of fluff. Also some fluff at the entry to the PSU. I managed to clear the worst of the visible fluff, but it looks as if there is fluff between the cooler and the fan. Fixed up keyboard and video - bypass the KVM switch. Turn on monitor, try to boot - BIOS display, then a grub error (disk error, I think). Power off, checked connections for primary drive but they seemed to be ok. Looked for a bootable CD, put it in, retried, grub gave me the normal menu (I need to catch the BIOS to boot from CD). Unfortunately, all the filesystems need checking after unclean shutdown. One reason this machine is slow is that it's only SATA-2 (3 GB/s). And although the / partition is fairly small, I have 100+ GB for /home, quite a large /scratch, and 700GB each for /staging (first stage of backups) and /var/tmp (tarballs to write to external disks). It was last updated to LFS-7.8, no progress indications on fsck. Thought I had overridden that, but apparently not. And when that completes I assume it will then have to check the RAID (3TB RAID-1) because of the unclean shutdown. So plenty can still go wrong, but things start to look hopeful. > > And on the boot topic I have been disappointed fixing clock chips in an > IPEX 133 "ex computer".
