So I just built my first PC and the display fails to pick up a signal. I have my usb connected with windows on so i assume it isn’t that. My gpu and ram and pushed in as far as they’ll go with pci cable connected to gpu. I’m confident I sat my cpu correctly and connected both cables (the large pin on and the 8 pin cpu connector) I've included pictures below, one of the full case and one of cpu connection as many seem to point towards that for the fault a lot. Any help is very much appreciated.
