i built this pc earlier today was working fine booted into windows all my components were showing up but when i moved it into my own room it wouldn’t turn on anymore no strip lights no fan lights no fan movement only the peripherals were blinking
this might be a stupid question , when you picked up the pc to move it did you catch the psu switch on the back of the case and turn it off. Even with it turned of the residual voltage that finds its way down the earth plug pin can make your peripheral lights blink.... thats why your phone still works during a power cut.
Okay so you're in the room where it worked before at the outlet it worked before and you've check the PSU switch is set to the I. Next open the PC and check that everything is connect to the PSU properly especially the 24pin to the motherboard.
