Laptop slows down and screen goes black?

So my laptop barely a month old is suddenly extremely slow. Sometimes he freezes briefly. And when I have Chrome on for about 10 minutes, the screen goes black like when it starts up at the beginning. It is not out, because after all it is still shining. I don't know what's going on and how to fix it

Reinstall Windows

The best thing to do is to ask someone to teach you the laptop.

What do you want to tell me

I think there are too many things starting in the background, this takes the load off into the task manager and switches off the things that use up a lot of CPU

Which notebook do you have?

Please exact name, then maybe you can say more.

Otherwise you still have a guarantee.

Asus zenbook 14 um431da-am011t

I saw it and the CPU is almost always 100%, but it is almost always 90% when used for services and controllers. How. Can I get it down now because if I switch it off it will go down

Thank you.

So he has enough power (so it's pretty fast).

So either reinstall Windows or send in the device.

Thank you very much

Scared cooling definitely
