New mainboard but monitor screen dark

I have just fitted a new PSU and motherboard - a Gigabyte 8S651M-RZ.  
http://tw.giga-byte.com/Motherboard/Products/Products_8S651M-RZ.htm

I added a CPU and memory and powered up but nothing much happened.  The cooling fan started spinning and the memory LED lit up, but there was nothing on the screen and no POST beep.  I have tried switching the speaker cable round the other way.  

I have no manual for the (Tiny micro ATX) case so I'm not sure what the different coloured case wires do.  Some are marked, others not.  The polarity is not shown on any.  Where can I find what each does ?  Could this be the cause of the blank screen ?  The power and start button are certainly wired up correctly.

I have the CD containing the drivers for chipset BIOS etc.

What CPU are you using?  Are you sure its a supported CPU?  I had a similar problem on a board with an Intel Chipset (865) that didn't work with Willemette CPUs, even though the manual clearly said from 1.6 GHz to 3.2 (the CPU I was trying was 1.7).  Do you have another CPU you can try?

I believe that is a supported CPU.  I don't have another I can swap it with either.  Could it be a duff motherboard ?  I guess such things do happen but it seems rather unlikely.  But then the only other option is that I have wired it up wrong - and that can't be the case :-)   I would expect a POST beep or two even if I had no CPU or memory installed.

I have now switched to a different memory stick and am able to boot to the setup screen.

Just one problem remaining - I don;t know how to find out which wires go whare.  The manual for the mainboard is fairly clear, but the polarity of the ones in the case leading to the HDD LED and soft reset switch is unclear.  And I have a green and 2 blacks with no labelling at all at all.  Whare can I find this out ?

Thanks.
