Question Error beep with CPU fan / video card

[fredmtl2024]

Hello everyone,

This is my first time posting here.
I built my own gaming PC. I put an AMD RYZEN 7 5700X CPU on an ASUS Prime B550-PLUS AC-HES AMD AM4 motherboard (+ speaker buzzer), and a Thermalright PS120SE ARGB CPU fan (with thermal paste).
For the rest:
- Corsair Vengeance LPX 16GB (2 x 8GB) DDR4 3600 MHz RAM
- WD_BLACK SN770 NVMe 1TB SSD
- Corsair RM850x Power Supply
Everything is new, everything is plugged in.
Problem: When I boot, I have a boot beep but nothing on the video output. Then an error beep is emitted. But I can't identify the error:
- If we consider 1 long, 3 short, Asus says it's a problem with the video card power supply. But for now, I'm using the motherboard's video output (I haven't put the dedicated video card yet) ...
- If we consider 1 long, 4 short, Asus says it's a problem with the CPU ventilation. However, the CPU fans are running ...

I don't understand the problem...

install a gpu, the Ryzen CPU you are using doesnt provide an integrated GPU, so your motherboard video ports are without signal.
