When the computer is restarted, the BIOS gives an error. Signal: 1 long, 2 short. After a few seconds, it loads normally.
Such a signal is usually issued by the motherboard when the video card is faulty.
If you turn off the STeinberg UR 24C, then everything is fine.
Maybe it’s your boot sequence setup…your pc might be trying to boot your operating system off an invalid USB device, like say your interface…you would likely have to check your boot sequence in the bios startup…make sure you don’t have any usb ports as an option on startup. I suspect the beep code is the bios telling you it can’t boot off that selected boot device…
Have you checked the beep error?
