Question above.
Tried different ram slots.
Tried holding the power button.
Tried removing the CMOS battery.
Tried removing the GSU.
Tried HDMI, DVI, VGA.
Tried different HDD.
Tried removing CPU and removing dust.
Motherboard appears undamaged.
Checked the CPU power cables at least a hundred times.
Tried monitor in another PC it works so does the cable.

Parts:
MB: Gigabyte A320M-S2H
CPU: AMD Ryzen 3 1200
RAM: Corsair Vengeance LPX DDR4 8GH 2666MHz
GPU: EVGA Geforce 210 DDR3 1024MB
PSU: EVGA 500W 80+
OS: None yet, planned Windows 10

When I removed the GPU I got beeps which I looked up to mean missing or damaged GPU (1 long, 3 short).
The monitor detects the computer but goes into energy saving mode.
Caps Lock light on keyboard does no turn on when pressed. (It's does work in a different PC)

Building computers is not my specialty, so any help at all would be useful
