I have 2 MSI gtx 970 and on load there is a buzzing sound coming them. I have tried each individually and they both buzz only on load. If I go into MSI afterburner and turn up the fans there is no buzz. Only on load. I have a corsair hx1000 power supply which is about 4 years old now. Could it be the power supply?
I saw someone else was having this issue on overclock.net.
I just finished building my PC like a week ago. I just noticed there is a faint buzzing noise while playing a game (the noise also comes out from my speakers). I tried to pinpoint the noise and turns out it's coming from inside my computer.
The buzzing noise sounds like it's coming from either power supply or graphic card.
