DP no signal. HELP!

[LTTbuen]

Built my first ever PC. Everything was going well for about two weeks then one day after turning on my PC, my monitor display says "DP no signal". I tried the HDMI cable and the result was the same " DP no signal ". I then tried to connect the HDMI to my laptop and the monitor and it worked. I don't know what to do. Please help me. More info about my setup:

It's strange that it would say no DP signal on an HDMI input. Did you switch over the input on the monitor?

Are the fans spinning on the GPU? Any indication of life?
