@AzardXD -- within Task Manager, in the first "tab", you can click on the column-headings to order the list of active processes, maybe by "CPU" or or "Disk", to find the process that is most active, namely the one that is producing the sound. Right-mouse-button click on that app, and choose "End Task".  Repeat, as necessary.
