Windows 10: Windows 10 pc randomly restarting, sometimes loud buzzing noise

Hello everyone, ive been having problems with my windows pc randomly restarting. I replaced the psu and the ram with no effect. I’ve tried looking up the event viewer codes but am at a loss for what could be the issue. Although the computer shuts down randomly, I have noticed it seems to shut down faster if the computer is simply idling, playing games specifically prolongs the restart. Any help would be a godsend

Thank you for your help. I ran the tests you told me to. Could you help me read what these numbers mean and what the root cause could be?

 

Loud Buzzing Noise during Videos

I have a Lenovo Yoga 720

I recently purchased it a few months ago.

I have windows 10.

Lately I have discovered there is a very loud buzzing noise, sounds like an electrical current or laser that is ringing when I am in a video call.

I cannot hear this noise during the video call, but when I am on video calls I am told the buzzing is so loud the other person cannot hear what I am saying.

I have tried to record a video of myself speaking on my computer and replaying it and I am able to hear the noise once I replay it.

I have tried to change my headsets and I have tried with and without a headset and the noise is still there regardless.

What to do ?

 

Computer randomly freezing with loud buzzing noise

First post here, and hoping to get some help.

For about a month or so now, my computer would randomly freeze with a loud buzzing noise coming from my speakers. It seems like it usually happens when I have Chrome up and watching either Twitch or YouTube. The only other thing I have up is Discord and Fortnite.

The freezes seem to happen pretty sporadically, sometimes several times a day while sometimes it won't happen for a couple of days. I can't for the life of me figure out what the issue is.

The things I've tried:
Turn off hardware accelerator
Updated video card driver
Windows Fresh Start
Using a different browser

Any help would be tremendously appreciated.
