The PC fails to power up following a recent rebuild.
Hello! I'm facing some trouble with my new PC after the build. This is the first time I've really puzzled over a computer problem. Once the motherboard powers up and the lights come on, the power button doesn't respond. After several repairs—swapping RAM, motherboard, AIO, power supply, and checking connections—I still don’t get any response. The PSU fan spins briefly before shutting off, but nothing else activates. I've tried everything: reseeding connections, clearing CMOS, removing the battery, flashing the BIOS, and even jumping the power front. My build specs are: Ryzen 7 5800X, MSI x570 S, 3070, 64GB DDR4 at 3600MHz, Corsair H100i Elite Capellix AIO, Lian LI 750W SFP PSU. I haven't changed the CPU yet and don’t see any visible damage. It feels like something might be faulty. Before considering a refund or return, could anyone offer advice? Thanks a lot!
