I ran memtest. It prints out "retrieving hardware info "etc. up until "Getting memory controller details" then the screen flashes and theres no video output, my keyboard and mouse lights go out and my pc boots into windows

i cant post a pic because it happens randomly and the lines last for a second or two (its not for the whole duration of the game it happens all of a sudden) is there a way to test if it is my vram?

CPU: AMD Ryzen 5 1500X GPU: MSI Radeon RX 580 Gaming X 4G, 4GB RAM: CRUCIAL DIMM 8GB, DDR4-2133 PSU: SEASONIC G-550W MOTHERBOARD: ASUS Prime A320M-K Sometimes at random moments while gaming my pc will just repeat the last seconds of audio output, my screen will scramble and show white lines. after that my pc stops outputting anything, no video no sound and doesnt take any input(my peripherals have leds and they turn off eg the capslock) and i have to force my PC to shutdown by pressing the power button. The moments when it crash dont seem like intense ones for my gpu either. Im on win 10. I am not OC. I have checked temperatures (fans spin) and no components go over 70C. I have fixed all corrupt win files using sfc and DISM. I have cleaned the pc a bit in case of dust. I have the pc for a year and it started doing this a month ago. I have checked for malware and i dont have any. when in windowed mode I can play bit longer. It happens for shadow of mordor and GTA if its in full screen. I have reseted my PC to no avail. I havent made any recent hardware changes. I used amd cleanup to get rid of all drivers and reinstalled them. I uses windows memory diagnostic and didnt get any hits. I havent switched out my ram or psu because i only have one of each. None of my CPU Cores are parked. What could be the cause of this or how can i find the cause of this?
