Ok so without turning the switch off on the psu my pc will power up on its own like normal and then sometimes will do a proper shutdown on its own iv checked my bios settings making sure its ability to power on itself is disabled and when i do turn the psu back on it turns into a battle to keep it on as it would power off like if i were to hold the power button but after a awhile of battling the pc it runs like perfect no errors in games no blue screens just fine cant figure it out this a new build
