Might be overheating. Do you head a fan running inside? Also make sure that all vents are clear and clean. You may want to carefully take it apart and clean all fans and cooling fins inside.

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

Turn it off first if you care for your laptop..

It's either your power cable/power adapter, a bad power connector on the motherboard, or a bad CPU/CPU fan. I had a dell inspiron something or another and my power connector on my motherboard broke so it would not turn on unless I had it a certain way but as soon as I moved it or bumped it, it would shut back off. If it doesn't power on, I'd say get rid of the Dell and go with something more reliable like HP, Toshiba, or Sony (just to name a few) Look on ebay or tigerdirect, or hp/gateway/etc for used laptops.  Good luck with fixing the hunk of junk from Dell.

Are you turning the computer OFF or STANDBY?

Are you making sure that you are shutting it down and not restarting?  It is a very common mistake.

Try to turn it off and if that doesn't work, call the place u got the computer from.

Is it a toshiba? there's a known issue with some tosh laptops caused by a flawed power jack connection.\n\nPS: dont quote me on this, but I heard that tosh won't fix it under warranty, despite the fact that it makes the laptop unsuitable for use as a portable device. If this is the problem & you are in the UK, there's a couple of independent repairers who can sure up the connection with epoxy resin saving you a lot of money.\n\nADD ON: I've seen your update, & it could be down to the issue I've mentioned. If you're not in the UK & this does turn out to be the problem, find a small independent repairer & if they start quoting silly prices for replacement parts, mention what I've told you here. \n\nIf you are in the UK, try the link below, although if you are outside of Yorkshire, transit costs may make the cost prohibitive.

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

It could be a ton of things.  Try these first:\n\nPop the battery out and plug in directly to the wall.  If it powers on, you have battery problems.  If not, jiggle the power cord in the back of the computer and keep pressing the power button.  If no luck, try doing the same while jiggling the cord to the wall or to the power brick.  You either have a bad motherboard or a bad power adapter.  Try another adapter if you can.  Is it on warranty? \n\nI just sent my laptop out yesterday with exactly the same problem...and it's either a fried motherboard or bad power adapter.

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.

My laptop used to do that and after I sent it off to the retailer it turned out that the fan had got blocked by dust and stuff on my desk. My laptop just used to get too hot and turn itself off, specially after using the CD/DVD drive, sort of like an inbuilt safety net. Just a really irritating one. It didn't matter if it was plugged into the mains or anything, it would get hot regardless. If yours is the same, you'll just have to send it in to get fixed and cleaned and whatever. I don't know about your files though. If all it is is it's just turning itself off, you could still keep your files, if you ask the people fixing it directly. I'm not sure about that though, since when I had this problem, my laptop also decided that it didn't fancy loading Windows at all, so my laptop got wiped by the retailer's workshop and had everything loaded back onto it when I got it back. I have definately become a big fan of memory sticks since then...try the PNY ones, or the SanDisk ones. The SanDisk ones have a password and everything. \n\nHope that's kind of helped.\n\nLaura

If it is a brand new laptop or if it is under warranty then the easiest solution is to take it back.  \n\nHowever, if you fell it is overheatingcheck to see if all the vents are clear, if not try unblocking them.  Aquick blast of air or vacum cleaner should do the trick.  If still overheating then the CPU cooler fan will be faulty.  Usually when CPU overheats it shuts down.  Not freezes.\n\nFaulty memory seems like a culprit.  Did you change anything  recently? Install software etc??\n\nCheck to see from the Windows Task Manager what processes and programs are running?  Stop unnecessary ones and monitor CPU memory usage.\n\nUse or run Anti Virus program and program like SpyBot or AdAware to see what they report.  whether there are malicious programs running without your knowledge.

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.
