Before I begin, I'd like to say that it's been a while since I last built my first PC. This is my second one.
So, I have built an ITX PC for a family member. The parts are
H370 Stinger
I5-9900k
Noctua L9 Chromax CPU cooler
HyperX Fury 16GB DDR4 2666mhz
M.2 SSD Samsung EVO Plus 1TB
Case: INWIN Chopin M-ITX (comes with a 150w PSU)
Upon finishing the assembly, I attempted to boot it but nothing shows up on the screen.
Symptoms I can describe are
1. White LED on top right of motherboard
2. CPU Cooler fan spinning
3. Case Power Button LED is lit
4. Monitor says no display detected despite connecting the motherboard with a HDMI
I've attached a photo below.
