Question No Display issue - ASUS PRIME H310I-PLUS R2.0 Motherboard

Hello,

I am building a new PC, and cannot boot it up as, whilst the machine appears to power on fine, there is no display shown on the monitor. I have checked the obvious things (connections, and so on).

Following the ASUS guide, I have disconnected everything except power, d-sub and 1 slot of RAM. When booting up, the PC speaker issues this:

Short beep shortly after pressing power. A few seconds then: Long beep, 3 short beeps, few seconds pause, then one last short beep.

Is that 3 or 4 short beeps?

3 signifies GFX, but I have no GFX installed, I am connecting directly to the Motherboard's D-SUB - So assume it isn't GFX
4 signifies CPU, but this appears fine. It's installed correctly, the CPU fan is working.

Its an Intel i5-9400 CPU, which is compatible according to the list.

I've also tried clearing the CMOS, taking the battery out and shorting the pins as it instructed. I assume this worked, but can't tell as there is no display and BIOS won't load.

Any suggestions appreciated

I assume so, the i5-9400F is in that list?
It's in the list so your issue isn't with the CPU. Maybe the BIOS doesn't support it? I know some of the 400 series AMD boards would need a BIOS update before a 3000 series CPU could be used. At least those with early versions of the BIOS.

Maybe the motherboard is bad?

Asus website shows different BIOS versions depending upon the rev. There should be a sticker on the board with a series of numbers the last of which is the BIOS version.
