Hi,

If have bought a second hand computer, an amd duron with a red
motherboard. The moment a plug in the power all the leds on the
keyboard start flashing simultaneously and non stop, until I power on
the computer. When I switch off the computer, the leds start flashing
again until I unplug it from the mains.

This probably indicates some kind of failure, but I don't know which
and did not find anything on internet.

Could it be a bad power supply?

Thanks
Piet

Yes it could be the power supply.

You might check the motherboard manual for a (PS2 or USB,
whichever the keyboard is) 5V/5VSB jumper and switch it to
5V, or it might be called a power-on keyboard or PS2, USB,
etc, jumper... this would help if the power supply simply
can't supply enough 5VSB current. If that is the case and
it's USB, another alternative might be plugging all USB
devices not needing powered when system is "off" on a a
different USB port that's jumpered to 5V or using a
self-powered hub.
