Random Black Screens on Windows 10

[Floobbb]

Hello! I sometimes get freezes then black screens for no apparent reason. It has not happened while playing a game yet. 2 weeks ago I reinstalled Windows hoping to fix this and after windows detected the gpu and it tried installing some old *** drivers but everything went black afterwards. I booted the PC again for a few times, it would start but windows wouldnt work. I downloaded DDU on a usb and I plugged into my computer and went into Safe Mode. Uninstalled the drivers, Windows started working again, downloaded the newest AMD Drivers and then the same thing happened. Took it to some guys for testing and they said that it worked great, what the hell, one day it works but on one it doesnt? Thant doesn't make any sense. After getting it back it surprisingly worked and I thought that somehow the problem was gone. But yesterday the random black screens started happening again. Please help

Hello. It sounds like your GPU could be quitting. If you have any other graphics card, or internal graphics, try to use that instead of the RX 480, and see if the problem was solved. Also, how old is your GPU?

The dudes I send my pc to, to stress test it for like a few hours said that everything worked perfectly. I have recently noticed that it happens only 1 min or so after starting the pc but just yesterday after playing watch dogs 2 and closing the game windows crashed again. Sadly I dont have any other gpu nor an internal one to see if the problem persists. I think that the GPU is 1 year old

Ok, doesn't seem like a 1 year old GPU would quit. Does your completely crash and need to restart, or does the screen just turn black until you restart?

Well windows freezes then the monitors lose signal and the leds on my keyboard and mouse shut down as well (even though the pc is still running, the fans in the pc are running etc). I have to restart my pc to make it open windows again. It may be an SSD problem it may be a PSU problem.
