Windows 10: Buzzing noise into a restart

Yesterday my Windows started doing a weird thing. My laptop freezed, started buzzing and restarted. I didnt really thing much of it because i manually installed windows 10 on my laptop through the media creation tool, and my laptop BSoDs anyway. I didnt really see anything so i cant tell if its a BSoD because my laptop is hidden in a bedroom commode and i use a external monitor, but it made that freeze, buzz and shut down.Ive seen someone else ask this and they asked for a minidump, so if you need i will give you a minidump.It might be a virus, but 4 antiviruses didnt detect anything.PS: The b

N95 buzzing noise

I also have that slight buzzing noise which is bearable and it doesnt affect my calls or anything like that

Though once in a while usually after the phone has been plugged into the computer and alot of file transfers and apps installed i get a much louder buzzing noise that kills the battery in like 2 hours the only way to kill the noise is to switch the phone off
and than on again anyone else have this problem

Handsfree buzzing noise in 5500?

I have the 5500 sport, and with the included handsfree I get the same kind of buzzing background noise that you hear from any speaker (TV, radio etc.) if someone is using his mobile phone close to it. I can reduce the buzzing noise by holding the phone
or the handsfree chord in my hand.
