Pc specs:
Mobo: FM2-A55m-E33
OS:Windows 10 home edition
CPU: AMD A10-6600k/6800k (don't remember)

1tb Seagate barracuda hard drive

PSU: Generic 500w PSU

Graphics card: RX460
My issue:

When plugging in my graphics card at first (when I bought it Christmas 2016) the card ran fine it was an rx460 and it had no issues then randomly I hadn't even touched my pc I was in the middle of a csgo competitive game and it just shut off and though my best efforts of booting it back on it wouldn't display the fans spun all lights were on on pc but though graphics card fans spun no display I was advised to change my power supply and I did so to another 500w compatible one and still no display yet onboard graphics work.
In the video I attached if you listen you can hear the fan sounding like it's trying to work harder but it then goes down again I am lead to believe this is the graphics card fan due to where I think it's comping from not to sure though

try using another gpu or put your gpu on another system.but from the sound of it,it could be the gpu.

If you have it, plug in a speaker into your motherboard and see if it reads out a beep code
