Hi. I assembled a new computer with the following components:
* Motherboard: Asus TUF X470-Plus Gaming
* Processor: AMD Ryzen 7 2700 (8 core, 16 thread)
* Memory: 2xCorsair Dominator Platinum 61C0023C2M4XG23DMC (on slots A2 B2)
* Power supply: Thermaltake Smart 750W model SP-750P
When the power supply unit is switched on, the motherboard's LED lights light on. After pressing the power on button (which shorts the PWR_SW connectors), the CPU's LED lights and fan are turned on and one short beep can be heard. Two seconds afterwards, one long beep followed with three short beeps are heard. The computer fails the POST test, and there isn't any image on the HDMI monitor.
I've read the user manual[1] and found the power-on self-test (POST) beep codes table on page 2-15, which states[2] that this behavior equals to a "No VGA detected" error.
Is the motherboard having any issues to start its embedded video card? What am I doing wrong?
Thank you in advance for your help. I promise to update this post with any further information or solutions.
