i would be checking the cooling fan first.if it is not running thats your overheating problem.not knowing how old your box is?-what version of windows or are you using windows  makes it pretty hard for us to answer.have you overloaded it?have you done a recent defrag-there could be several reasons.

Shut down your computer and wait a little bit and then restart to see if this will fix the problem;usually it does.

could be a hardware or heat related condition. if the fan for the cpu stops working, the cpu will get too hot and the computer will shut it's self down.

couple of ways to see if it is a hardware or a software fault\n\nfirstly boot into safe mode - restart your pc and keep on tapping the f5 or f8 key then select safemode\n\nleave it in this mode for a while - does it shut down ?\n\ncheck your event viewer for any system errors (in the control panel - administrative - then event viewer) click on the system \n\nsee if this gives you any clues\n\nalso try getting into the bios or cmos setup - again leave it in this mode - does it shut down - if so then you definately have a overheating problem\n\nalso check you in you bios to see if you have a hardware monitor option - if so check the cpu, system temp and fan speeds\n\ncome back to us with your results

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

1. It could be in Hybernate: try to turn off all power and restart the whole thing from the no-power stage.\n\n2. graphic-card / video setting: \n2.1 there's nothing much you can do if you cant see it but i suggest to turn it all off from the no-power stage and press <del> to go to your BIOS setting. Check if you can mannually overide the settings to a lower mode. If so, try restarting again.\n2.2 from the background, the laptop is starting up with windows but u cant see anything coz the video just might have been toggled with. try pressing <F8> by the time you boot it up, chances are u might be lucky enough to go on safe mode and u can level your video setting to a lower degree.\n\n3. if 1 and 2 doesn't work - i damn hope you have backed up you files coz you have to bring it to a DELL shop\n\nHope I helped you out- coz i had that prob once and # 2 did the trick for me

shut down and return?\nOr leave your computer on and return? It could be a whole host of problems. Thats not enough information to really go on.

maybe you have other programs that run behind it when you start the computer. Some programs are automatically on when you start the computer and some of them you don't need it to be turn on at the start-up.\n\nTo find out what's on, go to search, type msconfig. On the startup tap you could unchecked the programs that you don't need to be turn on when you start the computer.\n\nYou could also do disk cleanup or defragment to cleanup your computer. Go to start> accessories> system tools

You have a virus. It won't shut down because the virus prohibits the computer from being turned off. This is to corrupt data and transmit if you have any Internet connection. Please check your computer for a potential virus. It's best to be safe than sorry.

The laptop will go into a slight 'nap' which will mean that it won't heat up because it is not really running any programs. It is like it is taking a rest from it's work. When you switch a computer off it is like a human sleeping.\n\nHope this Helps

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.

Yes, I would say it is an overheating problem. Because it is a laptop I would recommend you to take it to a repair shop. \n\nThe laptop turns off to protect the cpu.\nWhen trying to turn it back on, it will turn it self immediately back off, because of the safety feature.\nIf it ever happens again this time wait 30 min berfore trying to switch it on again. I bet this time it will turn back on with no problems, because after 30min the temp. will be at an acceptable temperature.

probably you are not shutting down the system properly. Make you do it correctly.

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.
