Are you turning the computer OFF or STANDBY?

It will do this if the computer is not properly shut down. Let it go into safe mode, and use the start>shutdown function from there. If it insists on going to safe mode and won't start any other way (after you pick normal start) then there is a big problem and you may have to reinstall windows.

so the power sign is green, but when you turn it on its just black? well all your screen is is a monitor connected to the cpu, so you might have power failure to the monitor, but not the cpu. its the same as when your tower is on but the screen is off with a desktop.

yea this has happened to me before i think it has to do with your power supply, is this an older PC?  Pretty sure its the power supply shorting out a Lil and making it think its restarting

It could be that your fan has burned out.  If you notice the fan does not come on at all anymore, it's probably time to get a new one.  \n\nSide note... if your computer is in a room that tends to get warm, you're going to want to change that fan soon and/or use another fan (small household oscillating type) to cool your CPU unit.  If your system gets too warm, the whole thing will shut down till it has a chance to cool down again.

Why don't you just use the setting within windows to detect power.... if the laptop is running on batteries then have the computer turn off or go into hibernate.

Try plugging in your keyboard first and then turning your computer on. Where I work they have a very out of date computer and it did the same thing. We turned the power off and plugged in the keyboard. When we turned the computer on it worked.

I think you computer went into stand-by mode. To disable standby, Go to Start>Control Panel>Power Options.\n\nUnder Power Options properties, set power schemes to 'Always On'. You shouldn't have anymore problem after doing this.

If you are getting no power to anything then something is wrong with your power supply.

Sounds like your processor is over heating...that will definitely shut down your computer.

Go into your power options (control panel) and make sure that hibernate and standby are both off.

Take it in to a shop and have them look at your power supply. It sounds like that could well be your problem. If so, it is a fairly easy fix. Trust me, it happens way too often of late. Good luck.

Check for loose connections.  \n\nDesktop comps: If you think you have a bad power supply, you can test it by putting it into a comp you know is working or put a power supply you know works into the comp your building. \n\nGood luck.

Go look at your power settings in the control panel and disable standby.\n\nWhat happens when you use the start button to shut down the computer?  SOmetiomes viruses and bad stuff will hang during shutdown. Make sure your antivirus software is up to date and running.
