'Black Screen' to No Signal Monitor Display

[Helping4Fun]

Issue:

So, I was using the PC normally when suddenly it went to black screen, the monitor still says it is connected to HDMI. However it is only displaying a black screen. When I reboot, no BIOS screen, no display. The monitor went from connected into 'No Signal'. I tried rebooting and unplugging and plugging back the HDMI cable into the monitor and my graphic card's HDMI port. It will show connected to the HDMI port, but display a black screen. The motherboard still posts a single short beep which means normal to me. However after around 30 seconds, it beeps a normal beep. I have tried removing and inserting the graphic card and tested the HDMI cable and monitor by plugging my laptop into the monitor with the HDMI cable. Both the cable and monitor are working fine. However, I now don't know whether its the motherboard or the graphics card problem now.

Rebuilding the entire PC, taking out everything and rebuilding it.

Just to clarify the methods I have tried.

Try reseating memory and CPU.

I have edited the post, rather doing what I listed earlier, I have taken out all the parts and rebuild it, so I have removed the CPU and hard drives and started from scratch just to make sure nothing was loose. Thanks for reminding the CPU though. The GPU fans are spinning and the motherboard LEDs are on. So maybe it has to do with GPU or the motherboard's PCIE x16 slot? Not sure though.
