Have a problem with the motherboard?
You're experiencing some unusual behavior with your PC. The strange noises, USB issues, and RGB problems could point to a motherboard or power supply concern. It seems the PSU noise you hear when switching it off is typical, but the other symptoms might suggest something more specific. Checking for firmware updates, testing connections, and ensuring proper ventilation could help. If the issue persists, consider consulting a technician.
All concerns likely stem from power issues. The best course is to swap out the power supply or try it with a fresh, working unit. If that resolves the problems, proceed; otherwise, consider replacing the board. Usually, I suggest checking or swapping the cheaper suspect component first—here, the power supply—and power delivery faults could also be the cause.
If you have something you're familiar with or has worked before and meets the right setup, go ahead and try it next.
