Hi, so I just built my first computer and it was working fine (or at least I hope so) and pretty much all of the power on the PC works, the Fans, Lighting, etc. but when i try and plug in my Monitor and my PC it gives me a "DVI No Signal" I have plugged it in the Motherboard and the iGPU and still nothing :/, what else can I do to try fix this. I cant get into the BIOS bc it never gives me a chance.
