    Hiss from usb ports

    I get a high pitched hiss from the computer upon entry of certain usb slots with usb memory chips. I have never seen this phenomena in previous computers, is there any kind of manipulation available of the power/current of these usb or pci devices which might possibly affect their pitch?

    Getting hacked at a hardware/BIOS level?

    Out little home network has been the victim of relentless hacking for over 2 years. Something that may be significant is that when the hackers control our computers remotely, they are able to initiate a power-down on the computers. What I mean by that is that Windows 10 does not go through the...

I'm pretty sure it's not a visual bug in the task manager because I can literally...
