"It's shattering from time to time" - what's "shattering"?

 

[Drake973]

I mean shatter is an freeze from Time to time and I can't do anything for 25-35min and I have to immediatly turn it off by turn on button

Laptop freezes are usually due to overheating which is usually due to the inside being clogged up with dust. Remove the covers and blow the dust out.
