hello everyone , i am having issues with my computer i narrowed the problem down the psu and gpu. i replaced my CPU and heat sink and motherboard. The only things i haven't replaced is the ram, ssd , gpu and psu. The buzzing sound only happens when i use my 2060 which is the only card I have that has a need for external power my other cards work fine. i have figured out that the sound is from none of the fans. i have a strong feeling it is the psu because it sounds electrical and its new where my gpu was bought used.It turns off after 4 to 5 mins of max settings it reachs around 80c then video cuts , but the pc is still powered on . I cant find something of this issue anywhere.
