One bent pin on a motherboard
One bent pin on a motherboard
Your motherboard has a bent pin 8 on the left side and three pins starting from the bottom left. You’re unsure if one of them is the ground pin, so you tried installing the CPU and it worked fine so far. However, you notice a buzzing sound sometimes—could be coil whine or a CPU issue. You recorded the sound and think it might be the CPU. Decide whether to bring it to a repair shop or wait to see how it behaves further.
