Hello guys! Just wanted to say im having the same problem, after a long shut down my pc beeps 1 long time and 3 short times, i dont understand why that might be as my previous pc did the same thing, i sent it for repair which it didnt work so i got a replacement and it was working fine for 4 days, there is no problem of the screen not detecting it, and once i shut it off again and turn it on it does not beep again, however not shutdown is taking longer than usual, i do not have a power saving settings in my screen. Any help would be welcomed since this is new for me, and if i cant fix it im simply getting a new pc from. A different provider. My pc is a PC specialist intel core i7-9700 CPU, with a Geforce RTX, 2070 super, im using a MSI Optix G27C2
