Laptop freezing randomly

[Dorham]

Hey,
I have a Lenovo IdeaPad Flex 2-14 laptop (with the hard disk upgraded to ssd) running windows 8.1 which I've bought about a year ago.
Recently my computer started to randomly freeze. The freezes are random (as far as I can tell) and doesn't occur that much (about once a day or two), but once it freezes it freezes completely (can't even move the mouse) for about 20 seconds, and then it will keep freezing in short intervals until I restart the computer.
I'm not sure whether it's a software or hardware problem, as the computer isn't old, but recently a plastic covering broke (just a small piece covering the connection between the keyboard part and the monitor part) and I didn't get to covering it again yet. That also means I'm not sure if I'm on the correct forum, please tell me if I need to ask this in another category.

What can I do to help identify the problem and hopefully solve it?

Thanks,
Dorham

Interesting problem..

Can you check out the eventvwr and see if it provides any details?

So for some reason after posting the question my computer didn't freeze for about a week, and I didn't remember exact time of when it froze so I couldn't check the eventvwr. But today it froze just after I logged on, so I checked the eventvwr and I can't see anything suspicious.
Is there a way to upload data from the eventvwr from a certain time window so you can look if there are any details about the freeze (I'm no expert so maybe something is completely wrong and I just didn't realize it).

The events should all be in chronological order and you can sort them at the top. You didn't see any critical errors or alerts related to this issue?
