Just updated to Windows 10 laptop is stuck on the startup page

Hello,
So my Packard bełl laptop kept telling me to update to Windows 10 and I kept trying to avoid doing it until it pissed me off that much by popping up all the time, I just did it, now my laptop is stuck on the startup page, no mouse appears none of the buttons work, it's like it's frozen but it isn't because you can see the clock change, I really need help!!
