Minecraft is lagging for me, any advice?

Hey, this is my first post.
I used to be able to play Minecraft just fine up until a couple months ago. I had to hard reset my PC and MC hasn't worked since. I was kinda wondering because it's kinda strange. Even when I download Optifine it still lags immeasurably. I just was looking around for help, but I can't seem to find anything. Thx for the help!

I also tried putting all my settings to the lowest but I'm still getting just as much lag.
