I've got a mind blank here and can't remember which way round the
connectors go on the motherboard from the power switch etc.
All the cables, except the speaker, are coloured white and green, ie,
one side is white, and the other is green on each connector, and I can't
remember what colour is live.

Anyone?

Are you able to download the manuals for the mobo and the case?

I have downloaded the manual for the board, and it doesn't specify which
+ and which is -
It just says that the connection block (JFP1) is compliant with Intel
Front Panel I/O Connectivity Design Guide.

I don't have a manual for the case as it is an old one from years ago,
which I use for a 2nd PC

Maybe a later case from the same manufacturer would use the same colour
standards.

The coloured wires are always positive. ie. for the Power LED the
green wire is positive (pin 1) and the white (or sometimes black) is
negative. For the hard drive connector the red wire is positive and
the white (or black) is negative. The remaining two sets of wires
(power and reset) are on/off switches and can be wires either way
round.

Looking from the edge of the motherboard the positive wires always
face towards the left, so top row of pins will be power led (green to
the left) and the bottom row will be Hard drive led (red to the left)

Wiring the USB ports correctly is more important as getting this wrong
and connecting a USB device will alost certainly damage your
motherboard (usually either the onboard sound or PS/2 ports stop
working)

The normal wiring on most USB Headers is from pin1 (usually on the
left, looking from the edge of the motherboard) red, white, green,
black. Repeat this on the second row of pins. DOnt worry if there is a
fifth pin on the end, this is not used.

If you are not 100% confident about this wiring DO NOT take a guess.
It WILL damage your motherboard (and possibly your USB device) if you
get it wrong.
