Black Screen problem

[RunningNoob]

Hi guys, I'm new here and I just want to ask what the problem is with my pc.

So I've been getting these black screens that force me to reboot my pc. First, the black screen appears, can't really do nothing anymore. The audio still plays for about 5 seconds and then goes in a loop and then stops playing the audio. The computer is still running the fans and lights though(tried alt tabing opening task manager too). I've tested my ram and found no errors, same with my hard drives, cpu and gpu.
Here are my specs:

CPU: AMD FX 8350
GPU: Gigabyte R9 280x
MB: Gigabyte 990fxa UD3 R5
Storage: Samsung 850 EVO 500g
RAM: Corsair Vengeance DDr3 1866MHz 2x8G
PSU: SDGR 900e

OS: Windows 10

Update:Just happened again but with a white screen, Idk if that makes any difference. Please help me guys 🙁

how old is the SDGR 900e because its not a good quality PSU maybe your problem

Im sorry you are facing this problem, If i was you first i would remove my graphics card from my computer and use my Motherboards integrated graphics to run the system and see if it works or crashes if it doesnt crash its most likely your GPU or driver especialy if you use hdmi or audio input on GPU anyways
so if it crashes so that mean its not your gpu then i would look my motherboard Capacitors to see if they are all okay

No swallen capacitors,burned or whatever (even a little difference in shape is important) next i would check my Ram speed if it runs higher or slower than it should and keep on trying trial and error will get you straight to the issue

Can power supplies really cause this? If so I'm going to get a new one

My motherboard does not support onboard graphics 🙁 I checked the capacitors on my motherboard and everything looked fine (i had to see a youtube video to see what capacitors are and how to check if they were defective). I will try to see if my ram speed runs higher or slower though. thank you for the replies 😀 Update : My ram speed is fine, checked the bios and with cpu-z.
