Hello everyone. Thanks in advance for your help. 
My laptop suddenly froze while I was using it. Arrow stopped moving. I shut computer down, rebooted and now it's frozen on the page it stopped working at and is in lock mode.
I have no idea how this happened and have no idea how to unlock it. I've tried to sign back in under my password, successful with that but when doing this, I keep getting the same frozen screen as before.
Please keep in mind, I'm unable to scroll on certain pages because the arrow up and down is not an option in some circumstances and per my question, am unable to use arrow as its frozen
Trying to fix for 2 hours, to no avail.
Please help.
Thank you very much
