Hello!

To start here is my system.
CPU- Ryzen 7 1700x
MOBO- AsRock ab350 pro4
GPU- Sapphire Radeon Pulse rx580 4GB
RAM- Corsair Vengeance RGB 16GB (2x8gb) 2666MHz
Storage- SSD 240GB HDD 2TB
PSU- Corsair rx750m
Windows 10 64 bit

PROBLEM-
Computer will turn on and run but randomly the screens will go black and it will lose all graphics. The gpu fans are still running along with everything in the case. Also when the screen goes black my keyboard stays lit up but will not register keyhits i.e. caps lock scroll lock etc...
i have tried reinstalling windows as well as reverting back to older gpu drivers as well as older bios versions. i have run out of ideas and cant decide whether its a gpu or mobo problem. any advice or help will be greatly appreciated.

Thanks!

thank you for the response but will you please further explain what values i should be looking for? this is my first build so im still relatively new to all this. i ran the occt psu test but i did not know exactly what i should be looking for. thanks!

P.S. the power supply is only about a week old. i bought this one new thinking the psu was the problem, but it persisted after changing the psu. sorry for not putting that in the post.

i believe it is the gpu after multiple failed attempts at the gpu test. first i took one stick of ram out. problem still occurred. switched sticks and same problem. it will only run the gpu test for maybe 30sec-1min each time no matter what. would you agree or maybe im rushing to a conclusion?
