Glitches

Twice now my computer has come up with a message that it cannot load.  Then you have the choice of letting it try to fix itself or start Windows normally.  I think it has something to do with updates not downloading properly.  The first time it couldn't fix anything but just kept running the 'fix' program.  Then I tried shutting it down, turning it back on, and highlighting "Start Windows Normally" and it worked.  Yesterday the same thing happened so I let the fixit program run for a while.  Nothing happened so I turned the computer off.  This morning it works.  Go figure.  It happened both times after it downloaded updates before shutting off the computer.  Wish Microsoft would get itself straightened out.  I may have to look into a Mac if this keeps up.
