XPS 8960, turn off ok, restart stuck at Dell logo

Hello.

I had never used the “restart” feature as one of the power down options on this current machine.  It works fine if I just use the power down option.  The next time I turn on the switch, it powers on fine, although there are two strange things.  It is always the same startup screen (camels) and a few of my applications shortcuts use the default icon for *.exe.  I am worried about if it needs to update, what do I do?  Do I need to go through all that mentioned about safe mode, system repair, recovery, restore points etc.?  Thanks in advance.
