Random black screens since day one on newly built desktop

I bought my desktop a few months ago and have been having issues with it since. It will randomly go to a black screen with my monitor displaying" no signal" yet the computer is still on and running. It forces me to restart the computer, but the black screen inevitably happens again. I sent back my graphics card, got a new qc tested card, no change. Performed a memtest and found no memory errors. Performed a clean boot, still happened. I have event logs but have no idea what I am looking for. Please help and let me know what you think could be causing this.

Thank you,
