Hi,

I had a recent update to my laptop Inspiron 15 7559 and I turned it back on with no problems. Then it was freezing and so I tried restarting. Now it is stuck on the restart page. It has been about 4 hours and nothing will change. I tried holding down the power button multiple times. For 10 secs, 30 secs even longer. Nothing changes. I tried ctrl alt delete, nothing happened. I am not sure what to do, I have alot of data I do not want to lose.
