Hello, i'm new to pc building, this the third time i'm building a pc and got some problem with it. After i completed installing all the component everything look great, everything seem normal, but after sometimes when i start downloading driver etc. The monitor goes black out, keyboard-mouse goes unresponsive , can't restart button, even after i forcefully plug out electricity and try to start the pc it's still black out, not even get to bios setting, other solution i try is plug out the ssd its work for some times and goes black out again, i try clear the cmos battery on motherboard and its the same, after couples minutes is goes black again, and to go to bios setting again either i reset cmos battery or unplug ssd. My question is where is the problem? bad PSU or faulty motherboard? Both of them secand hand, i like to learn more about something like this, so in the future i have general idea what to do.

This is my system build :
Cpu : ryzen 3 2200g
Motherboard : msi a320m pro vd/vs v2
Ram : vgen tsunami 2*4 2666mhz
Psu : enlight 650w 80+
 
Solution
Try to change psu for test. If problem persist, then motherboard is problem.
Check capacitors on mobo. Could be distorded some on them...
Also check cables...
