Weird sound suddenly appears when I start up my pc, no Idea where its from.

Here I recorded the sound using my phone while I boot up my pc. I did a Virus scan both from Windows Defender and Malwarebytes, but both didnt help/detect anything. Does anyone know what this is? I also havent found anything in the start up apps in the Task Manager that could potentially make a sound like that.
