Build Info:
- CPU: Ryzen 5 2600
-GPU: GTX 660 (to be replaced with 1660 Super)
- RAM: Corsair Vengeance LPX 8gb (was going to add another 8gb stick)
-PSU: Corsair TX550M
  • Motherboard: ASRock Mini-ITX Motherboard - AB350 GAMING-ITX/AC
  • Storage: WD Blue SN550 250GB
Info on problem:

So recently I built my first PC with the above specs which until today was working fine.

I tried three things:
  1. Replacing the GPU with a 1660 Super
  2. Rotating the CPU Fan 90 degrees on the stock Wreath cooler as I had the common issue where the AMD logo covered a RAM slot
  3. Adding a extra 8gb of RAM in the spare slot in my Motherboard
After doing these three things the PC not longer booted at all (no fan spin, beeping etc).

I initially thought it was the PSU so I tested it using the paperclip method and the PSU fan seemed to spin (indicating it is working).

I have a feeling the motherboard may be fried but I am not sure why? What would be they best way you would recommend diagnosing the issue so I can send for a replacement part ?
