Hello,
I have put together my first PC recently but have not been able to get it to turn on for longer than a millisecond.

The Build:
  • Cpu - Ryzen 5 3600
  • Mobo - Asrock phantom gaming 4 B550
  • Ram - T-Force Vulcan Z DDR4 16GB
  • Gpu - 2060 Super
  • Psu - gigabyte P550B
When I power it on inside or outside of the case it wouldn't power on, the cpu and dram light would blink a single time for a fraction of a second and the cpu fan would turn a quarter rotation before stopping. I troubleshot it for a couple days and came to the conclusion it might be the mobo, some sort of short or something, so I purchased an Asrock B550 Pro4. Reinstalled everything and the same issue is arising. I have reseated ram a dozen times and quadruple checked the cpu and mobo power are fully inserted.

Does anybody have any ideas as to what might be wrong with the hardware? Or is it a rookie mistake I have overlooked? Thank you!

I got it up and running yesterday after receiving a new power supply. Bench tested it all plugged up and everything turned on smoothly, got it in the case and no issues.

Thank you for the reply though.
