I am stationed overseas. Purchased z390 Aorus Master through Newegg. Sent to my home of record in Florida, since I had a vacation coming up. Anyways, brought all the new components (full new build) to where I am stationed. Setup everything and had no issues for a good 20 days. Now board shows CPU led red and will not post. Regardless of what I try (different ram, different PSU, different SSD), only thing I haven't changed is the brand new i5-9600K. I doubt that somehow became defective, since I have been cooling it with a Thermaltake AIO 360. Tried the OC tool from gigabyte once, just to see the auto tune results. Temps were fine. Unsure how to resolve thos.
