Hi! so i bought my pc like a couple of months ago, so i have been experiencing a loud noise coming from the psu its like a grinding noise , now I don't know what to do with this, could it be a wire hitting the fan? but when i looked at it most likely not because when I turn on my PC it would make a grinding noise but when i turn it off the noise is gone, and later on comeback again once i shut my pc down and try to open it and so on, could it be just dust? because i haven't clean my pc since i bought it, or does it need lubricating? I really don't know helping me out would be great.
Edit: When i look at the psu fan when it is grinding the fan spins slow, and when i put my hand to see if there is any air coming out, there is none. But when i restart the pc the psu fan is back to normal
