I recently got a pre-built PC and I've been gradually making some upgrades. Today, I tried to install a Kraken cooler, but it required a USB header that was already in use. I unplugged the existing device and plugged in the cooler. Everything seemed fine at first, but my other two fans weren't functioning, so I used a USB splitter to connect both the cooler and the fans. After that, things went south—only a little light on my RGB cable lit up. I powered everything off to troubleshoot and plugged the original device back in, but then I smelled something burning, and now nothing powers on. I think the controller for my fans and RGB, since I lack an RGB header, is the issue. I removed that controller and tried to connect a smaller one just to get the fans running, but the system still won't start. I can't see visible damage on the motherboard, but I'm at a complete loss as to what else to try or what might be the problem.

It sounds like you may have indeed damaged the motherboard, especially since nothing is powering on. One thing to check is if you've removed anything plugged into the CPU_FAN header, as that’s usually required for the system to boot. Even though RGB configurations seem simple, they can easily cause issues if overloaded, especially when using splitters. It’s important to remember that headers on the motherboard have limits; exceeding those can fry components. If you mixed too many devices or used a cheap controller, that could lead to a failure too.
Exactly, mixing components and assuming they can all run together without specs can really lead to trouble. I’d recommend doing some research on your motherboard’s limits and ensuring any devices you use, especially with RGB, are compatible.
Honestly, it sounds like your motherboard might be fried. I get that you’re hoping for the best, but given the burn smell and now not starting up at all, it's likely damaged. It’s best to investigate thoroughly to determine if it’s just the motherboard or if there's other damage too, like the PSU. Sometimes, you can get lucky and just need to replace one part, but it sounds like yours might need some major attention.
That’s a bummer to hear. I guess I should ask—what signs should I look for to confirm it's the motherboard?
Check for physical damage like burnt traces or bulging capacitors. If nothing is visibly wrong but it still won’t power on, you might need to replace it.
Thanks for the insights! I had the same issue when I overloaded my headers. Definitely learn the specs and always check for maximum ratings before connecting.
