My main desk PC: Yesterday it spontaneously re-booted and then fell flat on its face during POST. I re-booted several times and got cascades of errors on POST including not finding the floppy drive, not initialising the printer and not finding the boot drive.

Tried this morning and it wouldn't even start POST.

Last time I had these sort of wierdies when adding a new HDD it was down to the PSU so out it came.

Yes! More bulging capacitors. Changed three that were low or zero value. Two were on the 5V SB supply. Explains why there has been a subtle strange smell recently next to the PC: Capacitor "juice"

Tested the other main caps and they showed correct values.

Re-assembled and the PC POSTed correctly and booted Windows.

One wierdie: Somehow the year had got set to 2019. That makes for some strange errors when accessing websites. Reset the date and all seems OK now but I'm leaving the side covers off for a few hours to be sure.
