Replaced the motherboard recently, but the computer won't start by itself.
Hey there, friend. I bought an Asus TUF Gaming x570 Plus WiFi motherboard and installed it for my system after the previous one failed. After setting up RAM, CPU, and graphics card, it won’t boot by itself. When I press power, nothing happens. Eventually, I have to use a PSU jumper to run the fans, then connect the 24-pin connector to get it started—this feels odd. I’ve also tried a separate power supply, but the same issue persists. Right now, the board only keeps the Aura sync lights on briefly before shutting off and requiring the jumper again. My setup includes a Corsair RM1000 1000W PSU, Asus TUF Gaming RTX 4090, AMD Ryzen 5600X, Corsair Vengeance RGB PRO with 32GB RAM (split between 4-8GB), two HDDs, two SATA SSDs, and an NVMe drive. Any advice would be greatly appreciated. I’m hoping it works so I don’t have to replace the board entirely. Thanks! - Ihopkins95
Your message seems confusing. It appears you're having trouble understanding whether your computer is functioning properly or if there are any issues with its components. If the computer doesn't respond, it might be related to the motherboard or CPU. Since you replaced the motherboard, the CPU should be accessible. Also, verify BIOS settings for power management and ensure proper connections when using the case button.
The power switch cable is connected properly, but be careful with those tiny pins—it's easy to misplace them.
LED power connectors have incorrect polarity and don’t function in this image. Also, they need to be active when it’s turned on.
The statement was purely illustrative, matching the diagram exactly.
This video explains the process described in the file you shared.
I’d take the board out of the case and try it on a breadboard to confirm there are no shorts inside. Perform the standard checks: leave everything else out except the CPU, one stick RAM, and the PSU. Make sure no GPUs, drives, or anything in USB ports are present—just to verify if it will start by shorting the two power pins with a small piece of metal (like a screwdriver). Inspect the board closely, paying attention to the back; look for any damage such as scratches that might be cutting through electrical traces. I own an LGA 1700 board that won’t power up, but using my phone’s camera zoomed in revealed a scratch on the rear connecting to two power traces. It seems the motherboard is likely faulty, probably because of a broken trace or a damaged soldered component. Unless it’s a short from the case, be sure the front panel header has the power switch connected to the correct two pins before you start dismantling.
