My sound card/device, probably the driver has a virus.

While starting the laptop by pressing the power button, the speakers make terrible noise. And then the browser gets froze, the start button also gets froze, cant shut down the computer. Have to press the power button, which then the start button works for few minutes and gets froze again. Reinstalled the OS, still has the same problem. Tried to shut down the speaker. Then there was another problem, on power button, it went to windows boot manager, asking which OS want to use, though I have only one OS, and one hard drive, therefor on my computer, right click, went to properties, advance settings and had to make changes. Finally I had to mute my sound, which is causing the OS freeze.
