Change front page from a post page

Hi!
I am quite new to WordPress. I started working with a theme called I-Max. Everything is working fine except my front page is a post page. What I want to do is to keep the layout but to make it a normal page where I can put my content. If I change the front page to a page I′ve made, my slider and the whole layout changes. Is there anyway to fix this?

Here is how it looks atm. I simply want the design from my post page to be on my custom made page.
