Acer Helios 500 PH517-61 Laptop starts giving out noise

GunYari

Just wondering if anyone here has the same problem I have. Recently my laptop starts giving out noise, I'm not sure if it's from the fan or the motherboard but the noise is pretty loud. I'll paste the sound file here and hopefully someone can help define it for me. One more thing, my headphone jack's a little strange, it takes a little while after I plugged my headphones for my laptop to switch from speaker to headphone, I wonder if that's only me. Wait for the speakers to switch to headphone every time. (5-10 second)  Why?
My laptop is Helios 500 AMD PH517-61~
