Just built a new pc . After one month or so I started having trouble turning it on. I would turn it on and all I would get is the monitor to stay idle and would leave the power button on the monitor In breathing mode but all components like fan , gpu rgb,rgb would all work.(monitor is also brand new and worked on another computer) After A ton of attempts it finally turns on and after a ton of repairs and blue screens of death it finally worked randomly. I Uninstalled some anti virus cause it said it could do that and then Played for a few hour and turned off to come back the next day and the same thing. . I took out all the cables and plugged them all back in swapped ram cause I thought it was that and Nothing. Swapped gpus still nothing . Both gpu and ram that I did swap were both brand new (friend let me swap to check)I took out all the pwm fans and rgb cables and tried that and nothing. Now all I have is the components working but nothing showing on the display. So it’s either the psu, mobo or cpu. Anyone ever have this issue if so what did you do what should I do? Here are my specs and thank you for whoever responds.
