And the only clue it's an old PC is XP, tell the forum about your maintenance.

My desktop shuts down normally (and the fans stop), but after a second or so reboots. I don't think the cause can be:
(1) Windows XP (installed on the hard disc), because the same thing happens when I boot and run from a Linux live CD;
(2) the hard disk, partly for the same reason and partly because the S.M.A.R.T. data are all satisfactory;
(3) the network adapter, because it is disabled and is anyway not allowed to wake the computer; or
(4) the BIOS, because Wake on PME and Restart on Shutdown are both disabled.
Has anyone any bright ideas, please? Thanks!
