Hi, My PC with a H370M-ITX/ac makes 5 short beeps when is turned on, but boots perfectly fine. According to what I can find online, these beeps would lead to a missing GPU. I have a Core i3-8300, which has an integrated GPU. The system does not beep when a screen is connected (I use HDMI). However, when I unplug the cable and boot the system, it beeps, but as said works fine. I use this system as a NAS, so I don't need the screen. At the same time, I need the beeper to know if things go wrong. It didn't make these 5 beeps until I reinstalled the OS (Linux) and disabled CSM options. Does UEFI mode create this issue? Can you help me? |

That is normal, the actual beep code indicates no display output is active. If you have a display cable connected and are not getting a display and it beeps 5 times then there is a GPU error. You can just ignore the code. -------------

Thanks for your reply! This code was not produced when using CSM/Legacy mode, is there a way to disable it in UEFI mode? I turn on my system every day, and is very noisy :( |

OK, looks like there is an (external) solution: buy an HDMI dummy plug that simulates a monitor on the other end. I will go for this one since they're cheap and should solve the problem. |

I typically just disconnect the PC speaker and only connect it when troubleshooting  -------------

I can confirm that a "dummy HDMI plug" bought from Amazon works fine, emulates a display and eliminates the 5 beeps. Hurray! I keep the PC speaker connected because the OS I run on my NAS interacts with the PC speaker to tell the user if a specific activity is completed or not. |

Thanks. Was facing same thing when I forgot to connect Display Port cable after cleaning. Good to know that this is a feature and not any issue. |
