I was using my computer (I think it's Windows XP), and the screen randomly went black and it said "Monitor going to sleep". All of a sudden it came up with this black screen with commands on the bottom right corner and there was that blinking underscore where you type something. Did my computer lose all of its memory or did it just restart by itself?. Created by Anonymous. computers-internet-en - hardware-en - desktops-en

Rebooting and restarting are the same thing. It sounds like it rebooted. Sometimes computers just do that. But maybe you pushed clicked on something or pushed a button on accident. That happens to me sometimes too. It doesn't hurt anything. Usually your computer will ask if you'd like to go to your previous activities.Good luck! :)
