My pc is making some strange noises and I have no idea what does them.The noises sound of some sort "fluuuuuuuu" kinda.I mostly didn't notice but my friends and family keep saying it's pretty loud.I tried with Google and YouTube but all I got is nothing matching the sound.PleaseI think that it may be from gpu cause I'm playing games that are just killing my gpu,but the sound is continuing night-time when nobody use it.It's just turned on but nothing running on it.I'm begging for help!
