GPU or CPU failure?

[mason1989]

Specs:

Ryzen 3200g 

Gigabyte B450M DS3H AM4 mobo

16gb DDR4 3200

Sapphire RX 580 4gb (latest driver)

Seasonic Bronze 550 PSU

 

All parts are new except GPU (1 year)  and PSU (PSU used for 5-6years)

Rx 580 started coil whine when fans were hitting 2900-3000 RPM and made heavy load games to go black screen (sound were looping on background still).

Restarted desktop couple of times...and using Afterburner to set custom fan curve, I've managed to keep it at 75c and 55% 2200 fan speed.

But after like 15min into heavy load game, it turned black screen again, NOT a force restart but black screen with sound still going/looping.

 

I would like to figure out if possible that is it GPU or PSU is causing this issue. 

Any ideas and helps will be appreciated!!

 

if there is anything I didn't specify, LMK!!

1. Try swapping GPU with another and if it problem is solved then 580 was broken.

2. Maybe overclocking cpu or gpu.

Maybe a undervolt or a underclock?
