Unplugged drives, no POST. 0d error is immediate.
Should I re-seat CPU again? (Skylake seating design is terrible...)
Thanks for the complement on the build. I have been a Lian-Li guy forever, but am very impressed with the Corsair case.
Update: I pulled the CPU cooler and stared at pins with a magnifying glass for 20 mins. No bent pins. Re-installed.
Still no POST and "0d" error.
