Question Pc freezes with an annoying buzzing sound

[Azmain Iqtidar]

I was playing valorant today and suddenly my pc totally froze up and started making a buzzing noise. I couldn't bring out the task manager or anything and couldn't move my mouse. I had to use the power button to shut it down. I don't know I'm very much concerned about this as it has happed before sometimes. But nothing like today, it happened 3 times in a day. I would be very much grateful if someone helps find out the cause and fix it.

Thank you
