Screeching noise

[Henry22]

So when I start my car up in the morning there's a screeching noise that happens pretty much non stop under the hood. When I put the car in reverse the noise picks up a lot more and faster. The noise is constantly going unless I start driving around fast and it seems to "warm up" then the noise is a little less noticeable. Any help is appreciated, very annoying, thanks.

Pull your serpentine belt off and start it up for a little bit. If there is no noise then it is one of the accessories that the belt drives

I'd guess a bad tensioner which is allowing your belt to slip. Very easy to replace.
