Having trouble with a B450M Pro4 that won't boot. No video and weird USB (keyboard/mouse) behaviour. Frustratingly I'm not getting any diagnostic beeps (I have a speaker connected to the spk pinouts). I had read that the default setting in the bios is for the beeps to be disabled. If so, how do I enable them without access to the bios? Or is this board just fully fried? Have gone through the full list of diagnostic steps including a hard cmos reset and swapped most components. |

What are the specs (including PSU model)? Is this a new issue on a previously working system or a new build? What (if anything) caused the issue? -------------

New build. PSU is known good. Tried multiple GPUs. CPU and ram could theoretically be bad but confused as to how they'd cause the symptoms seen here. Base question though: why am I not getting any beep codes? Are they indeed turned off by default? (I get the boot beep being off but diagnostic beeps in case of a fault should really always be on). |

| You PC restarts every 30 seconds or so? |

| Nope, never starts at all, and no apparent restart cycle. Looking like it may be an RMA. Still confused as to why no beep codes though. |

Generally no beep codes = bad. As far as I am aware the "disabled" setting in the BIOS only disables the POST beep. Errors should still cause a beep code. -------------

| Thanks for that Xaltar. Definitely confirms there's something wrong with the board itself then. |
