Hi
Not sure I get Bears comment about hijacking, maybe he's seeing something different then I am, I don't see more then one question here.
But anyway, we do need to have more information then you are posting.
What kind of computer?
Did it come with Windows 10 or is it an upgrade?
Is there any message or blue screen when it hangs?
Are you running Google Chrome?
I ask this because running Chrome makes my computer hang and I have no idea why?
Do you have a lot of data that you don't want to lose on your PC?
It makes a difference as to approaches for fixing your computer.
Mike
