You spend hours meticulously cable managing, picking the perfect RGB setup, triple-checking every power connector, and finally hit that power button with the confidence of a god. Nothing. Dead silence. No POST beep, no fan spin, nothing. Suddenly you're transported back to the Stone Age, questioning every life choice that led you here. Did I forget the motherboard standoffs? Is the PSU switch off? Did I seat the RAM properly? Is the 24-pin connector ACTUALLY clicked in or just pretending? Spoiler: it's usually the PSU switch. But you won't check that until you've disassembled half the build and contemplated returning to monke.
