Currently I'm playing Clash of Clans.

Clash of Clans is a 2012 free-to-play strategy video game developed and published by Finnish game developer Supercell.

The hardest game I've played is Swordigo .

Swordigo is a 2012 action-adventure platform game created by Finnish indie studio Touch Foo.

The best racing game I would recommend you is Asphalt 9: Legends.

I have purchased a new laptop. It's only a month old.

I think buy a new PC is the best option as the new PC will work smoothly as compare to the old one.
