One question:has the PC been working with monitor and all working properly at some stage. Or is the a new installation.

If the plug is square it is most likely the 12volts power supply for CPU fan on some motherboards. Don't worry about it, your motherboard does not require this connector and it probably gets the 12 volts from a different connector. Check your old motherboard to see if this connector is for a fan. You can power up and check this connector's voltage with a multimeter.

In such cases its practical to change the SMPS with a working power supply of the same rating and then trying it out. If with the new power supply it works fine then cange your SMPS. Also make sure that all cables are snug tight and generally ree from dust. The same applies to your RAM too................sodeep
