My Computer Is Frozen Up Solid!

Approach 1: Press Esc twice.
This action usually doesn’t work, but give it a shot anyway.

Approach 2: Press Ctrl, Alt, and Delete all at the same time.
If you’re lucky, Windows Task Manager appears with the message that you discovered an “unresponsive application.” The Task Manager lists the names of currently running programs — including the one that’s not responding.
Click the name of the program that’s causing the mess and then click the End Process button. You lose any unsaved work in it, of course, but you should be used to that.
(If you somehow stumbled onto the Ctrl+Alt+Delete combination by accident, press Esc at the unresponsive-application message to return to Windows.)
If that still doesn’t do the trick, try clicking the Task Manager’s Shut Down menu and choosing Restart. Your computer should shut down and restart, hopefully returning in a better mood.

Approach 3: If the preceding approaches don’t work, push the computer’s reset button. When the Turn Off Computer box appears, choose Restart.

Approach 4: If not even the reset button works, turn the computer off and choose Restart from the Turn Off Computer box.
