Mini freezes and buzz sound

[Fan7o]

My headphones happen to randomly buzz from time to time, for half a second. When it happens during video gaming, the game freezes for that brief time. In the worst cases the buzzing/freezing last longer (2-3 seconds), few times even permanently (need to reset pc). It's like it doesn't manage to keep going, and it gets stuck until it works again. I tried changing video card, updating drivers... But it didn't work.
I don't really know much about pc, these are the specifics i know about mine:
AMD FX 6300 six-core 3.5gz processor
RAM 8 gb
windows 10 64bit system
AMD R9 380 video card
SSD 250gb
HHD 1tb
I also have an energy saver or what it is called attached to the pc (to keep it on in the case electric energy blacks out at home). If more is needed to know, pls tell me how to check it so I can tell more.

Headphones and sound are not at fault, it's your system that causes sound to freeze along with system.

Now I tried to load from an older backup, but the system says it finds an error and it can't be done.
What should I try to troubleshoot the problem?

Check health of disks and RAM too.

disks are fine, if not for the hdd temperature, going up to 46°c after some gaming (is it that bad?). ram is fine.

ps: running iobit antimalware found out bad things that malwarbytes ignored, fixing that solved the freezing problem.
thanks for the help
