Razer Blackwidow elite weird inputs I don't think it's hardware

Randomly doesn't detect spaces/backspaces, randomly treats single quick key inputs as continuous inputs. randomly while using the keyboard, any key I press will act as if it is being pressed continuously, and once I press that key again it will stop. For example, I will be playing a game and I will tap "S" for 1 second to move backward briefly but it will continuously move me backward, and if I'm pressing "D" to move right I will then begin to move back-right, so south-east, once I tap the "D" key again it returns to normal. There is no physical damage to the keyboard, and it happens to multiple keys. It's so random it's impossible to track. this began about a month or so ago, no major changes that would've caused it, it's only this keyboard so I believe it's razer software. I have gone into synapse and deleted the keyboard and reinstalled drivers, no avail. another thing, this keyboard often doesn't detect inputs when inputs are coming in fast, for example: I will use space bar and then backspace with about half a second delay, and 5 times out of 6 it will space and then backspace, but one of those times it will space and not backspace. and even though I am pressing the backspace, it will not go through at least once. . almost as if there is a lag, as if something is lagging and if it happens during a key input it will lag out and continuously input it as per the first issue.
