What are the signs of a bad motherboard that I should be aware of?
I’ve been experiencing some issues with my computer recently, and I’m starting to worry it might be the motherboard. It’s been acting up more frequently, and I can’t seem to pinpoint exactly what’s wrong. The system occasionally crashes without any warning, and sometimes it won’t even boot up properly. There are strange beeping noises during startup, and once in a while, I’ll notice certain peripheral devices not being recognized. Additionally, I’ve seen unexpected errors and stability problems, even when there’s no apparent reason. It’s frustrating because it feels like a mix of different issues, and I’m concerned that these could be signs of a bad motherboard. I’m looking for some clarity to understand if my motherboard might be failing and what specific symptoms I need to watch out for.
