Hey I have the asus b550-F gaming WiFi motherboard and all the fans in my P400a case are not spinning except for those connected to the aio cooler. Also, I have no  output to my display. The rgb on the fans are working, they are just not spinning. Any ideas?

Yea I just realized that’s why there was a light, however I’m still not getting any output to my display. I have a display port cable and keyboard plugged in that’s all. My monitor just turns on and enters sleep mode after like 10 seconds.

Those are usually debug leds so they turn off after boot has competed. if your getting monitor output this means your on the vga boot sequence. Your motherboard sometimes boot circles meaning reboots a couple of times before full booting. this is normal behavior for motherboards. If your are having vga/graphics issues if reseed the graphics card

@viper_the1st Did you find a fix yet? I've been having the same exact issue with my b550 f and I'm ready to give up.

Yea I plugged in the 8 pin at the top left of the motherboard. That fixed the fans not spinning but not that I couldn't post. 

 

Then I swapped the ram sticks and then I could post.
