Laptop remains 5-9 p. Hanging and buzzing?

My laptop always stops and stops responding and it starts to hum loudly. What can I do about it?

Humming sounds like a high-revving fan. If it then goes out then to protect the electronics. So against overheating damage. I would suspect from afar.

My guesses:

overheating
Bad sectors are on your hard drive, they can't be loaded and it hangs. (Just check hard disk for errors or run chkdsk)
Your pc has a very bad ram or bad video card, depending on what you do while it's buzzing.
You have too many programs running in the background

Solution: Disable programs from the system start

No, it's not overheating or anything, and it's not the fan that buzzes, but the speakers.

Can't be, because it does not get warm.
can be, I have to look
8 gb ram and 920m geforce
does not apply too.

Oh so…

Since I would check the times whether the possibly broken or are connected wrong, or if another device generates vibrations in it.

Memory (HDD) full.

Fan clean? If it is a bit older, then carefully clean fan and cooling ribs with a long-haired bristle brush and blow through.
