Computer crashed and will not turn on?

I tried to open a hour long video I recorded myself with fraps ( a recording software ) and then everything stopped responding ( Minecraft Google chrome vlc media player Skype ) and it crashed And will not turn on occasionally I see "asus starting automatic repairs" "asus diagnosing computer" also this is a windows 10 computer if that helps

Try starting it and as soon as you do- keep hitting the F8 button.

That should put it in Safe mode (unless the brains at Microsoft decided that gives you too much control).
Then look at the menu and it should have something saying "Restart at the last known good configuration". Or something like that.

Use your down arrow key to highlight it and hit ENTER.

If that doesn't help go back to Safe Mode and try System restore to about two days ago (or before you downloaded your video.

Do not mess with it. Switch on the computer & leave it be. Locate your HDD light. It will be illuminated or flashing, meaning W10 is fixing the error. The login screen will display when completed. It may take 5 - 10 minutes
