Why does my computer shuts down automatically ?

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.

Well there could be many reasons for this.  One is that you have so many processes running that it takes Windows a lot of time to shut them all down - and/or that one or more of them become non-responsive.  If it is this, then all you'd have to do is wait and it will either eventually shut down or give you the "End Process" screen one or more times.  \n\nIt could also be that your shutdown script got corrupted, somehow, and aborts.  This could be from the reason below.\n\nOne other possibility is that your computer has been infected with a virus that interferes with the shut down process.  \n\nMy suggestion is to try it from Safe Mode (if it shuts down that is).  If it does, get current versions of a few antivirus programs, Adaware, and Spybot Search and Destroy, reboot in Safe Mode and scan with all of those programs.  You should also invest in a good registry cleaner program and run it regularly - believe it or not, your problem could originate from a single registry problem.

If by „shut down” you mean it powers itself down, its obviously adapter problem (could be both software corruption or hardware malfunction). \nIf by “shut down” you mean you loose internet connection, check time of LAN DHCP lease in routers interface.

the computer turns off, because you might be eitehr using MS windows 2000 or MS Windows XP service pack 1 which had lot of errors. USe MS_windows XP Service PAck 2 for the computer to run better. Hope it solves your problem, enjoy.

This is not nescessary. whenever the computer shuts down, everything in memory is erased. If you are looking to remove a process that runs and is taking up ram you must locate the actual progam that is loading that process into ram.

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.

On laptops the main reason for shutdown is overheating. First make sure the fan in back/bottom is working. If it is not, it will need to be taken to a shop for replacement. Check the back fan area for dirt buildup and clean it with a can of air. Also do not use the laptop on things that will block airflow such as in bed on blankets. A laptop cooling pad (has fans in it) helps also.

Your computer is turning off because you have way too many problems running while you play your computer game. Applications such as games really slow down your computer. if you press alt ctrl delete all at once it brings up the windows task manager. from there you can see what programs are running. click on the ones that you feel are unneccessay and then click end process. BUT MAKE SURE THAT YOUR ENDING THE UNNEEDED PROGRAMS. if you dont it can cause ur computer to crash. or if ur too scared to do that just x out and programs such as internet explorer, aim, etc that are on while your playing that game. by the way what game are you playing and what kind of computer do you have

There are softwares using which you can set timers to shut down, restart or hibernate your computer. But I don't know whether there is a software to automatically start it. \n\nHave a look at the link below. I use that software and it is very useful for downloading large files. You can set a timer to automatically shut down(restart, log off, etc etc.) the computer or disconnect your internet after the download is complete.

try clicking altogether ctrl+alt+delete and click shut down. if it's still not working, you have to contact your pc manufacturer

It is possibly overheating. Check the fan. Check power supply, it could be going out. If not:\nYou probably need to reorder your BIOS by hitting del on startup. If you dont know how to do this please dont try, get help first.\nHere is a search of this problem, choose one of these forums that seems most similar to your system and ask them. They should be able to help. Its hard to troubleshoot a problem on Yahoo Answers as we cannot easily have continuous dialogue.\n\nGood Luck!\nhttp://www.google.com/search?hl=en&q=computer+restarting+over+and+over

you have a lot of "stuff" running in the background or something like drivers or programs are conflicting and XP has to deal with them before shutting down. Also if you have restore points activated it could be saving a restore point

If you are using windows xp, properly shutting down the machine is best when not using it for extended periods of time as the operating system carries out routine maintenance of your drives/files during boot up and shut down. When you shut down everthing will stop apart from the built in clock (battery powered) the machine has to be on for any processing to take place.

If it does only during startup then its the BIOS setting that holds the key. But if it does quite often during your normal working, then a virus could be a culprit. Another reason could of some program which has been run from the drive and stopped adruptly and its still seeking its home from the background.

Your computer shutting itself off can be a symptop of 4 things.\n1. Windows power saving settings. This is unlikely to be the problem if you are using the machine.\n2. You're on a laptop that has run out of battery life. Trying using only your power adapter.\n3. You may have a defective motherboard, processor, memory RAM, video card, or powersupply. My suggestion is to always start with the cheapest to the most expensive. I'd try replacing your Power Supply with one of quality with sufficient wattage(not the cheapest power supply you can find). I have found that AMDs are more sensative to power flucutations as when CD-ROM drives and Harddrives spin.\n4. The mostly like possiblity is overheating. As mentioned on here, most new motherboards have a temperature threashold that will automatically shutdown your PC if it gets too hot. I suggest making sure you have sufficient air circulation (cool air coming in from the front, passing over your motherboard, and out through the rear exaust). You should have a quality heatsink attached with thermal paste (helps avoid heat pockets being trapped between the processor and heat sink). On the heatsink you should have a fan that is clean of dust and rotating at its proper top spead. \n\nAnything else is just random and rare cases.
