I am out of ideas and hope this community can help. I have built a new system and it will not complete POST. The system shows white(VGA) and green (BOOT) lights, beeps are one long and three short. I even RMAed the MB and new (recertified) one is doing the exact same thing. Specs and troubleshooting steps taken and boot video below.
What should be my next steps? Could the KF CPU be an issue (no internal graphics)? If I am going to start trying replacement components, what should I start with? RAM is probably out of the question b/c DDR5. Components:
ASUS STRIX Z690-F GAMING WIFI
G.SKILL Trident Z5 Series Model F5-6000U3636E16GX2-TZ5S
Intel Core i7-12700KF
(Removed) EVGA GeForce RTX 3080 Ti FTW3 ULTRA 12G Graphics Card (12G-P5-3967-KR)
(In for troubleshooting)EVGA GeForce 210 (Small, passive, known good)
m2_1 SAMSUNG 980 PRO M.2 2280 250GB
Corsair RMx 850 PSUTroubleshooting done:
Changed slot of GPU, then changed GPU entirely to eliminate power issues.
Changed slot of 2nd GPU
Reseated RAM, CPU, and M.2 Drive
Complete rebuild in new Mobo, same issue. Video of boot attempt:https://www.youtube.com/watch?v=3N5M5-GBZI8
