Concerned about my GPU bottlenecking

[HelloJello]

Windows 10 64bit, 2 - 8gb 3200mhz DIMM, Ryzen 7 3700x w/ case fan, Gigabyte RX 580, Corsair CXM 650 PSU, 1tb WD HDD storage, 1tb WD m.2 nvme boot drive, Asus Strix X570e - gaming motherboard.

 

All of the most recent driver updates have been installed and it runs fine normally for youtube and daily task. However, as soon as I start any game the frame rate drops significantly I can get up to 125fps when standing still, but when I move my cursor even slightly the game will freeze for a few seconds, lag, or even shut down. This was a second hand build so I wont complain as its my very first build but there is obviously wrong, and I would like to sort it out.

Needs more ram, slap another stick in there and clean up your internal connections.

Doesn't seem like a hardware issue. While the 3700X is way more powerful than a 580, it shouldn't be doing that, do you have your game settings set on something crazy like 4k or something.

I guess another stick of ram wouldn't hurt.

No, even on very low it will stutter.

 

Thank you both for your input

Went to go and get some more ram cleaned up the internal wiring and the problem still persist. Do you have any more suggestions?
