I upgraded my computer last spring by installing a new processor and GPU, which meant I had those components ready for use. I decided to assemble a system for my daughter using just the motherboard and RAM, leaving the rest to others. I purchased an Asus Prime B450M-A II motherboard and Corsair Vengeance LPX RAM (2x8GB at 3600MHz). This weekend I began building, assembling quickly to test before putting it in a case. The setup failed to power on. I checked the CPU and found it wasn’t fully seated in the socket. After applying pressure, it finally went in completely. Removing and reinserting the processor didn’t damage it, so I thought it was fine. Still, it wouldn’t boot. I tried adjusting the CPU power connection, ensuring fans ran, but nothing changed. Eventually, I disassembled my current machine to replace faulty parts—parts I expected to be reliable since they worked when removed last spring. Nothing improved. I switched the GPU and replaced the power supply, yet the issue persisted. My conclusion is I might have received a defective motherboard and should consider returning it for repair. I also wondered if adding a CPU cooler could help, but that seems unlikely. I’m stuck and would value any suggestions.
This situation seems quite serious, could be a bent pin or something lodged in the socket. Let’s focus on the CPU base and check the socket closely. Updated November 19, 2024 by leclod
I see your worry, as it matched my own. I've tried to capture clear images, but from what I checked, bent pins weren't present. The part appears normal if you place it in the socket without forcing it. This leads me to believe the board might be faulty and a replacement is necessary.
It was a simple doubt. Did you release the lever before inserting the CPU? In the second photo, part of the lever is visible on the right side of the CPU and it’s secured. Regarding the socket and pins, they appear fine (the last three images), even though they might look a bit odd up close. Good luck!
