Windows 10: Computer going dum di dum dum

My computer has started going dum di dum dum every minute. If I restart it goes away but a couple days later it starts up again. It starts in the morning when I first start to use the computer. It is a desktop running Windows 10 Version 20H2(OS Build 19042.1110. Windows Defender has not detected anything.

Battery is going crazy!

Hi,

During the past week my phone has been randomly turning off, not even managing to play the (dum dum dum...) sound meaning that its shutting down, it just doesn't seem to have the power to.

Then 5 minutes later when I turn it on again, the battery seems to be almost full...but then 5 minutes later it dies again.

I am wondering if it is a problem with the battery or the phone? Can I get the battery replaced for free, as it is fairly new. (I do not have the reciept (bang myself in head))

Yes the battery is an original, bought at a nokia service center.

Thanks in advance,
