Toshiba lapt wont boot or do anything even in safe mode

Hello,

My daughter has a Toshiba laptop. It has window's 8.1 which we hate. I was going to upgrade to Window's 10, but this happened.
She was watching a video on you tube and the screen froze. She restarted the computer and it just stays black. We have tried everything, to re boot it. I have to log in a pass word to get the HDD to start. Normally this takes you to the log on screen. Now the computer wont go there.

I tried to get to the safe mode, but the computer is so slow, it wont even do that.
I am now living in Canada, and we bought the computer in the US, over a year ago.

Is there any options? I don't want to re-boot to original settings,, again... We did that a week ago and had to re-install everything.
