I currently got a new pc and I have connected all the necessary leads to the correct terminals and when I turn my moniter on it provides a blue message 'No Signal'. I have an AOC or NOC I don't know what letter the symbol represents. My pc is an AMD Quad Core Configurator. see information here: https://www.cyberpowersystem.co.uk/system/AMD_Quad_Core_Configurator Please help as soon as possible
