Has your motherboard failed?
Has your motherboard failed?
Hello everyone, I recently acquired an i5-2400 processor and decided to upgrade my setup by purchasing an LGA 1155 motherboard from eBay. The build went smoothly, and I even managed to capture a video signal from the motherboard and checked the BIOS. However, when I attempted to disconnect the PSU to create a case, nothing happened. The fans started moving slightly as if they were about to spin up, but then stopped completely. Unfortunately, the PC wouldn't boot at all. I tried replacing the PSU, thinking it might have failed during installation, but it didn’t help—possibly the failing PSU caused the motherboard to shut down.
It’s common for unexpected issues to arise. A power surge can affect any component, sometimes reaching parts above the main board. That’s why the PSU is considered one of the more dangerous elements in a PC. However, if you’re fortunate, there might be an easy fix. Could the motherboard support a debug system?
It seems the system is reacting to a short circuit and activating protection. It’s likely triggered by something outside the case being detected. Are you using the same power supply as the one installed elsewhere? You might try testing outside the case again to confirm if the issue persists, which could point to a fan or another component failing. If it resolves, inspect related parts inside the case.
It’s more recent than mine and I already have those. They seemed to offer more functionality than they initially appeared. If nothing is active, it might mean they’re off or not detecting any issues even with the devices present. The quick point @Beerzerker could point to a fried motherboard, but there’s also the chance of a screw in the case behind the motherboard—lucky you if that’s the case. It’s not just about unplugging cables.
