Hi updated to latest bios on this motherboard. Installed Windows 10 but for some reason it's always booting into bios and never automatically into windows. The only thread I found that might shed some light on this issue is here : https://rog.asus.com/forum/showthread.php?106447-PC-only-boots-to-BIOS-first-have-to-manually-boot-W.... Apparently it's an issue linked to a CPU Fan error message and plugging a VRM fan to the CPU_Fan header solved the issue. Now, I'm also getting this error. This is my setup : MOBO: ROG CROSSHAIR VIII HERO WIFI CPU : AMD RYZEN 9 3950X GPU : AMD SAPPHIRE RADEON VII RAM: 32Gb G.SKILL TRIDENTZ 3200MHZ FANS: 3 BEQUIET! SILENTWINGS 3 120MM HIGH-SPEED PWM 3 NOCTUA NF-A14 140MM PWM CHROMAX BLACK FAN HUB: THERMALTAKE COMMANDER FP 10 PORT HUB FOR PWM FANS Now in order to make sure I'm not having any Amp issues hooking up 6 fans to the mobo, I plugged all these 6 into a THERMALTAKE COMMANDER FP which I hooked up into the H_AMP fan connector. I modded the GPU by putting 2 extra BEQUIET! SILENTWINGS 3 120MM HIGH-SPEED PWM thru a Gelid CA-PWM-02 (PWM Fan Adaptor for VGA Cooler Fan), but those are independent from the fan headers from the mobo. Now with this setup I always get the CPU Fan error msg and I'm always booting up into bios. Is there some sort of incompatibility between Windows 10 and the H_AMP fan connector ? If so, how can I solve the problem?
