I have just fitted a new PSU and motherboard - a Gigabyte 8S651M-RZ.
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.
