Is it possible to become autistic when you weren't born autistic?

I used to be very charismatic and had lots of friends but then I started playing minecraft and a couple of years later I think it's possible I became autistic from hanging around so many other autistic my brain absorbed their cancerous autism and it spreaded to me.

Is this possible?

My processor doesn't give me as much fps as it should?

I have recently upgraded my processor and gpu. I used to have a AMD a6-6400K with Radeon HD 8470D GPU.
Now i have AMD a10-7700K with the Radeon R7 graphics.

I get 80fps on minecraft however my friend has the exact same specs and he has 200+fps…

How can i fix this?
