The symptoms you describe could be many things:\n\n1. Most likely, an overheating CPU. That's bad.\n\n2. A loose memory module or other component on the circuit board. That's most likely if the computer has been moved, jarred, etc. or it's a laptop.\n\n3. A loose connection in the power supply or a bad power supply.\n\n4. An electronic problem of some sort, as in an electrical component is failing.\n\n5. Possibly, a loose battery connection or bad battery.\n\nWhatever the case, it needs to go to a geek for diagnosis and cure.

Are you turning the computer OFF or STANDBY?

I'm guessing by the sounds of it you have a dead CMOS battery. It's a little battery(looks like a watch battery) that keeps all that info like the system clock stored when you have the computer turned off. If that was to die you would be getting messages like this. I reccomend you replace it(if you know what you are doing) or bring it to a computer store and have them do it and it should fix the problem.

Is the computer on standby? If it is then you should shutdown the computer instead. \n\nRun an antivirus program on your computer to see if a virus may be the cause as well. Also check to see if you have had any recent errors, like driver conflicts or "the blue screen of death". That could also be a cause.

I had this problem before, I fixed it by reseting the bios to it's defaults, unfortunately I never did find out exactly what bios setting was causing it though. You can take a look under the "power management" section of your bios and see if you can find it, or just do like I did and reset it to defaults.

It doesn't sound good.  Sounds like something got fried. Possibly either the CPU or Memory.\n\nIf you don't see any lights on the motherboard, then it's possible the motherboard has fried.\n\nIf you hear beeping but no video, then that's probably the memory.\n\nIf you see lights on the motherboard but nothing else happens, then it's probably the CPU.\n\nNo matter what, it's not good. If you don't feel confident in swapping parts like the memory or cpu, then take it somewhere.

Is it a laptop or desktop? If it is a laptop maybe it is overheating. If it is a desktop start in safe mode and turn off the settings to never shut off for everything and see if it still happens.

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.

Hi my friend\n\nMaybe listen i said "maybe" there is virus on your computer but before that you want to change your windows you should know that sound's like a hardware error bcuz virus can't do like this \n--->"the green case light remains on for few mins/secs"\ni think there is and error on your mother board.\n\nthere is a thermometer under the CPU socket that sometimes  didn't work correctly and send over temperature signal to mother board to shutdown the computer.\nyou can go to the bios menu and set the  automatic CPU temperature value = ignore or disable \n\nform your question i understand you have temperature problem or one of electric parts on your mother board or your system power doesn't work correctly .... \n\n"i turn it on many times and shuts down each time faster than previous so i turn out to have it like goes into windows and shuts down imedialty at the last tries"\n\nSo try this \nignore thermometer\nTest The computer power \nTest The Mother Board

The behavior you are describing is serious and is probably related either to a configuration with your motherboard, a problem with the CPU or similar.\n\nYou should definitely return it for service.

#1 - you need to be more specific about what you are trying to do and when, since your problem could come from a hundred different causes, BUT\n#2 - try turning your computer OFF, leave it off for 20 seconds, and turn it back on. Is the problem still there?

make sure your computer is plugged in!!

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 your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

You'll likely get various answers as I can already see.  No, it doesn't really damage it but think about this, you turn it off and then immediately turn it back on, one minute 500W (my power supply) of energy is flowing through your system and then not and then immediately it is again.  I hold the belief this causes unnecessary wear and tear on the system and if you are only going to be away from the PC for a short time, put it in standby or for longer times hibernate and shut down at night (or whever you sleep).  But, if you are having a problem with Windows and task manager is not responding, press the reset switch (if you have one) which is a far better solution than turning it off and immediately turning back on again.\n\nJust my take.

If you have already checked the battery, what about the AC adapter cna you run it just on the mains, does it shut down. \n\nIf it doesnt shut down, it just may be that the battery is faulty  or even check the power save/optimisation settings.\n\nIf it does shut down then check the following:\n\nLaptop overheating - make sure none of the vents are blocked/clogged up, when in use.\n\nProcessor Overheating - CPU fan may be faulty, so processor starts to overheat and system shuts down to protect the processor.\n\nGet it checked out by a pro, to be safe.\n\nGood Luck\nBattery Wizard

I'm sorry to tell you but I think it's dead. The click of doom is never a good sign and if there is fire involved? Hell, you're lucky the damned thing even turned on. You need to get a new hard drive man.
