Carrying ranked games (pls give advice)

There's probably a lot of threads like this on here but I'm gonna go ahead with this anyway.

I really need some advice for my ranked games because I've just demoted to silver 4 and I don't know what it is I should be doing different. I recently made a role swap to top lane from jungle since I found jungle just wasn't working out for me and I like a lot of top lane champs, and I've also found that I'm winning lane in top a lot more than I'm losing lane. I'm out csing the enemy laner and I'm getting first turret in a lot of games. Yet my teams seem to just go into ARAM mode regardless of whether I'm there or not and I'm frequently losing games because of it. In the last game I played I won lane as Gnar against a Darius and my bot lane won their lane as well. At one point I killed Darius and pushed my lane out so I could roam down to help my ARAMing team in mid since I knew we could win a team fight as a 5v4 with all my CC, yet before I even get close to mid I find my team fighting between enemy turrets and getting wiped. Next thing I know my bot lane that won now has a negative KDA.

How am I supposed to be winning these games where I'm winning lane but my teams consistently hard throw and become aggressive towards me when I try offer them advice or simply tell them that they shouldn't be taking those fights? Is there something else I should be doing in order to try to carry and direct my team into better fights? I'm starting to feel like ranked is a lost cause with the amount of lp I gain dropping with each game.
