When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time. You state shipping it overseas, where were you located initially and where did you relocate to?
A good starting point would be to inspect all components and if they need a reseating. Following that, check all connection to your devices and from your PSU and if they're fully seated.
