Cannot open anything

[Kay1188]

I did a software download of Windows 10 on my dell laptop. It worked perfectly. Today when I opened it up nothing opens. I can go to my desktop but that is it. The computer is 100 % charged. It was fine last night.

Then I would ask a friend or go to the library or something.

I went to task manager but it would not work.
Then I pressed FN and the power button. I waited a short while and turned it on again. Was able to get to desktop and onto Google. It appears to be working.
Thank you very much for your input.
