Question Buzzing noise when gaming that stops when I go off the game

Welcome to the forums, newcomer!

Sounds like coil whine or a cable brushing against a fan blade. You should roll a sheet of A4 paper, hold one end to your ear while the other end is used to probe for the source of the sound.

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.
