Windows 10: Gaming Laptop Performance

I've been using my new gaming laptop for about a month and suddenly the performance of it went downhill when i tried playing games now. It used to instantly load things and now it takes time to even load a single click. I don't know why or how this is happening. could this be one of my drivers? is something interfering? did a setting change after the major update?
I just want my laptop how it was before. Fast and great. I play a lot of Team Fortress 2 fyi

:)

 

Laptop with broken screen How much?

I would like suggestions and look in local stores. I dont wanna buy a laptop from someone online. Sorry. But could be a good idea if you asked him about the performance on older games. Gonna make a list ofall laptops people suggest me.

Remove the screen for space purpose here its small desk and if the screen is opened it will hide my 22 inches lcd
