Windows 10: Computer acting weirdly after startups

So for a few months now, my computer has been acting very strange. Most of the time it turns on with no issues, but sometimes once a week or so my computer will start into a blue screen. I'll restart the computer and it'll allow me to log into windows but the computer will continue to act very strange until I restart a few more times then it'll be fine with no issues again. Any ideas?

Why does my Enter and Backspace act weirdly?

• #1

I have an Asus X540-YA laptop, and sometimes when I press the Backspace, instead of deleting the character, it writes down the combination of "74321", and sometimes some dots as well. Same thing with my Enter, sometimes it just types "nbz" instead of jumping
a line when typing. I have tried to restore my Windows 10 the the original settings and re-install a driver ASUS sent me, but it did not help. Any suggestions what could cause it, or what could I do?

 

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?

 

My laptop acting weirdly

I have a problem in my laptop

it acts weirdly whenever i'm typing on keyboard

for example when i'm on notepad++ and writing something and i have more than a tab it moves from tab to another while writing but if i didn't touch the keyboard nothing happens.

and something else when i'm on Facebook chatting with somebody suddenly it starts opening photos from the timeline and the same if i didn't touch the keyboard nothing happens.

what would be the problem and how to solve it.

Thanks
