Listen to me!!!  Your computer is very pissed off at you.  When you ignore it for 5 hours, it'll ignore you in return - very much like a woman ;)  I would seek the advice of a professional counsoler.  It wouldn't hurt to buy it/her a new light or fan.  Chocolates and flowers won't cut it.\n\nOK, seriously.  Everyone else is right.  Your computer is going into a power save mode.  You can adjust these settings in "Control Panel -> Power Options".  Just change the first pull down to "Always On".  You can still enter hibernation - click "Turn Off Computer", hold down shift, and click "Stand By".\n\nIf the problem still persists, then look into lights and fans.  Saying I love you once in a while doesn't hurt either.

it's not the operating system that makes your system hybernate it's in the bios you cant turn it on or off you must not have that feature on board why would you want to do this anyway just turn the thing off if your not using it.

You are probably shutting it down when you still have some programs running. Close all programs by yourself before shutting it down.

Based on the details you just provided it sounds like it is overheating and it shutdown to prevent the components from frying, literally.  Try just starting Windows normally but it sounds like you have a problem with cooling.  Perhaps some of your case fans have failed, perhaps your CPU fan failed or they just need to be cleaned.  Assuming it was a heat warning, you're going to have to take your computer apart (or at least open the case) and see if all the fans are coming on when you boot it.  If the CPU fan isn't working most likely you wouldn't have made it past the BIOS check.  At this point this is just a guess and not a very good one at that.  But as you said, it gave you a heat warning... "and talked about it" doesn't mean much to us computer geeks and you'll have to be as specific as possible.

If this is a problem that started out of the blue without you touching any of your settings, chances are there is a problem with either your motherboard, graphics card or processor. I had this same problem and it turned out that my motherboard had burnt out.\n\nI don't know how old your computer is but if it is more than 3 years old, chances are it is burnt out and you will need to replace your base unit.

Your PC is shutting off, because you have two or more Anti-virus programs installed and they are not compatible.\nYou need \n1 Ad-Aware\n2Anti-virus\nand a good firewall

There's a maximum time limit that a normal PC can stay on. Typically 7 days for a normal PC unless you have a Server which can stay on forever.\n\nSo, I think possibly that you have a PC and keep it a point that if you continuously keep your PC on, it will get dead very soon. Normally a PC can stay on continuously for 7 days only unless there are branded PC which can stay for months but not years like a Server.\n\nI suggest that you Turn Off your Computer when you dont have any work and then turning it on back, when you need it.\n\nBYE

If the computer shuts down a short while after trying to connect to the internet then it is probably a virus. To verify that, close your internet connection and leave your computer open. If the problem persists despite having closed your internet connection then it could mean a hardware problem. Use one of the freeware internet programs to monitor your computer's temperature. If all appears normal there, it might be another virus (check for abnormal processes or cpu usage at your process manager) or a recently installed DDR chip that does not quite agree with your computer or a software installation that did not complete quite succesfully. If none of the above is the case I should advise going to the hardware store from which you bought the computer and ask some professional advice

heat is what kills a computer, well heat and dust.  you should have some times were your computer is off, as it can help it cool down, also you don't wast electricity.  \n\nmy home computer is on almost 24/7 though.\nIt has an excellent cooling system (its a computer I built so I know its done right) and when I am at home I am normally using it, when I am at work I remote connect to it so I can go to any pages work blocks (job hunting lol) and when I am asleep it is downloading programs. I run it off about one night a month, just to let it shut down, if they are on to long they tend to run kinda funny and sluggish.\nif I am not downloading anything I do turn it off to save power.\n\nwith it on all the time you might also get more dust in your fans and heat sinks, you can clear this out with a can of air, you will be amazed how much dust is in that little thing between your processor and the fan. the dust also keeps your computer from being able to cool down, and heat kills computers (also why you shouldn't place a laptop on your bed or other surface that cuts airflow)

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.

On older computers turning it off shut off ALL power to the system.  The starting "surge" shortened the "life expectancy" of  many parts, mostly the power supply capacitors.\n\nOn newer systems, ATX and later, power is NEVER removed completely from the system except with the power supply switch, (on the power supply,) or unplugging the system, and the answer is NO.  (I turn my systems on and off as much as 5-10 times a day, depending on which systems I am using at the moment, I have SEVERAL!!)\n\nTurning a system off and on should NOT affect the speed of operation.\n\nPossibly you should check for viruses, spyware, and/or other malware that may be running.  MANY game sites install some type of "monitoring" software without your knowledge that runs in the "background".\n\nAlso, games tend to cause lots of "cycling" of files to and from the HD and result in fragmentation of the files which DOES slow a system after a while due to reduced free space and/or increased search times for the game files.  Suggest you "defrag" the system, and see if this helps.

It´s ´probably just going into "Stand By" or you need more time in your energy savings config. \n\nGo to Start> Control Panel> Display >Screen Saver> click on the energy saver button> there is a combo box that says turn off monitor change that to 10 minutes or 15 whatever you like.\n\nThis gives you more time to levae the computer an d the monitor won´t go off.\n\nhope it helps

All programs have to shut down before the computer can shut down.I sounds like you have alot of programs running in the background.You can go to the start menu and click on run,when the box comes  up that says open,Type msconfig and click ok.Now a box with several tabs will appear,click on the one that says start up.Now you can uncheck allexcept the ones that say windows system or kbd for the keyboard,now click apply then close and restart computer.When computer restarts,a box may appear that you can check to never show this again.If this does not help,then I would suggest that you have a memory or ram issue and the computer needs to be serviced by a professional.\n\nGood luck and I hope this helps you

Maybe your power supply just failed or something isnt snuggly plugged in. It could be that something got caught in the fan and it shut down from over heat automatically

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

How often does this happen?  Is after it consistent length of time?\n\nI think your friend's computer has Power Saving enabled and perhaps the monitor is scheduled to switch off each time.  Go to:\n\nControl Panel/\nPower Options/\nPower Schemes\n\n... and check the options at the bottom.  The monitor may be set to switch off after a time lapse as short as 1 minute.\n\nIf in doubt, set all of the options to never.\n\n'Hope that helps.

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?
