If a computer often switch off from the butten without going to shut dawn mode, could it be damage to the pc?

Yes it surely does damages to Your Hard Drive. Thats Why Windows Run Scan Disk After ABnormal Turnoff. You better keep Shutting off your pc properly.

Only if you dont restart or shut down your computer can you avoid that welcome windows. \nIf your Compputer can start in hibernation mode, then instead of shutting down your PC, put it in hibernation mode. \nBut that means ur computer is like on 24-7. it takes less power, but its still on! and some times you have to restart wen you install something!!\n\nIn a Hurry, Use HIBBERNATION

A General rule of thumb is that if you have no good reason to leave your computer on don't.  You will lessen the chances of your computer being influtrated if it is not on 24/7.  However, you can leave it on if you wish but ensure that you have taken the proper precautions:\n1) Have an anti-virus program  (i suggest PC-Cillin by trend micro)\n\n2) Have a good Firewall program\n\n3) Have good proactive spyware program (i suggest Spy Sweeper by web root)

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

Nope - turn off the monitor, though, because that consumes a lot more power than the computer itself. Leaving your computer on is actually even better for it, because most failures happen when you turn it off and back on.

any wire can carry a charge, and a thunderstorm can hit any wire outside your home.... so if your computer is connected to 1) a power outlet or 2) any other wire such as phone or broadband, there is a risk that lightning will hit the right line outside and send a gigantic current to your computer (destroying it)... so yes, unplug your pc completely (leave the keyboard and mouse...)

What ever you decide to do, do NOT leave your computer running all the time for no good reason.\n\n1> Would you leave your car running all the time just because your starter or other parts might wear out from turning it on or off?\n\n2> Your computer uses the equivalent of 3-5 light bulbs of electricity. You wouldn't leave 5 lights on in your house all the time without a good reason.\n\n3> Sleep mode stores everything. When the computer "wakes up" it comes back with everything that is in memory (good and bad...) If there was an error in its memory, that comes back too. When you reboot, everything loads fresh.\n\n4> Hibernate is a little better than sleep.  Hardware has a hard time waking up from sleep a lot of times.  Hibernate effectively turns off the hardware completely while it is off.  I like hibernate a lot better than sleep or standby.\n\n5>  Shut your computer down when you are going to be away from it for a long time.  You decide what a "long time" means to you. It's okay if you leave it on all day or for a few hours at a time... Just don't leave it on if you aren't going to be using it.\n\n6> Keep in mind that electronics hate heat.  The hotter they get, the worse they run.  Leaving your computer on all the time subjects it to heat that it just doesn't need.  Under normal conditions, heat isn't a big problem:  The computer deals with it with fans.  However the longer you leave your computer on, the less normal the conditions become.

Best to turn off for a number of reasons.\n\nSave electricity\nProlong life of components within the computer\nCertain items will need refreshing which is done during reboot\n\nI'm in charge of a PVC mixing plant, the control PC's that handle large amounts of information the automated operations are on most of the time because they are needed for production.  With time they slow down until a point comes where it is unbearably slow and the operator decides to reboot, which resolves the problem.\n\nMore chance for hackers to gain access if you are connected to net.\n\nWithin my company all non productive computers must be switched off since if left on and unattended they can be fire hazards\n\netc etc

turn off the computer

just leave it on.\n\nthat's my answer.  but you do have to edit your power preferences so your computer doesn't turn off after 2 hours of non use.  other than that, I don't know.

The answer changes because there isn't just one right one. Power cycling your machine stresses parts as they heat up and cool down, cope with inrush current as they come on, and so on. This is not good for the life of these parts, but if they're able to survive for a decade you probably won't care by the time they fail as the machine will have been retired in favor of the much more powerful computer hat that will be available.  \n\nHowever, only the military and the space people design stuff to such high levels of reliability, and even they (or their suppliers) get it wrong on occasion. \n\nSo the question you're really asking is, will power cycling my machine more often than x times cause trouble. And there's no one answer to that. Leaving the machine on causes problems (dust deposition impeding proper cooling if nothing else) and uses electricity, so that's bad. Turning it on and off causes problems (that stress stuff mentioned above), so that's bad too. And leaving it off, isn't so hot since you can't use it when it's off. \n\nThe answer to your question is therefore a sort of balancing act you must perform, but without full information for your particular machine on the relative damage / costs being caused by leaving on as contrasted to turning on and off. \n\nThe best (not definitive) answer I've ever found is to turn it off when you (or someone) won't be using it for a few hours. If you'll be back in 15 don't bother -- except that security issues may suggest you not leave any software running or that you should log off or some such. Gone for the evening, turn it off. \n\nA last point has to do with particular parts. All sorrs of  monitors can burn a pernament pattern into the screen if left on for long periods. That's why there are screensavers, to keep the display changing while nothing else is going on. And CRT type monitors both draw a substantial amount of power (Energy Star monitors will shut down to a 'warm off' if not used for a while), but also have quite high voltages internally which cause more than the usual amount of electrical stress on insulation, capacitors, and such. And the LCD screens use cold flourescent tubes to back light the screen; they're expensive to replace in almost all cases, so their limited lives shouldn't be frittered away in useless idleness. Even if you don't turn off the rest of the machine, consider turning off the monitor. \n\nYou should also consider that the mechanical bits will have a limited life. Consider hard disks. If your machine keeps the disks spinning whenever the power is on, you shouldn't leave it a 'rotatin when the machine isn't being used. Disk death may take data with it and that's not a nice thing. Perhaps even a complete disaster. Many machines shut down drive rotation after a certain duration of disk inactivity. Check yours to see what it does. \n\nSame goes for cooling fans (in power supplies, mounted on the CPU, or video processor chip, attached to the back of the chassis). Some CPUs (and video processors) draw so much current that, without the fan cooling, they will fail permanently from runaway overheating in minutes if the fan fails. Some systems have temperature monitors for the CPU (and alomst never for the video processor chips) which will cause an emergency shutdown of the machine if the temperature goes too high (ie, if the CPU fan fails). Yours might, and that's good, but your software had better not loose data when that happens, or scribble all over the hard disks as the power goes down. If it doesn't, you probably don't want to leave it on when someone isn't around to take quick action if something fails. If you get an option, the ball bearing fans have longer lives than the roller bearing ones. But they cost more. \n\nThere are multiple considerations in answering your question, as you can see.

I can only tell you about leaving your computer on 24/7. \n\nLeaving it on all depends on how long you leave it on, and what kind of computer you have. If your fan isnt very good, your computer might overheat and cause a malfuction. Id get some kind of program that can see how fast and how hot your computer is getting.

It is better to switch it off. This is to increase the efficiency and life span of the PC. \n\nIf you are using Windows XP, then you might want to try the hibernate option. When u restart the computer from hibernation, the PC gets back on the desktop much much quicker than a normal starting process, thus saving sometime.
945392
No duh. That shouldn't be a surprise.\nIn hibernate mode, the computer is practically off.\nIn standby mode, its on, but only by a small thread.\nGive your computer a minute or so to restore the connection.

No if the PC is off no programs can be active.But you can set a program to start when the computer starts if you want to automate tasks while away from the compurer.

Go to CONTROL PANEL and then click POWER OPTIONS and choose how long you want your computer to be on when you're not using it.

Your "system idle process" should normally be very high when not much else is happening - it's Windows' way of saying "this is the unused CPU capacity". As far as the light always being on, it may be a software issue. When in doubt, take the machine to a PC shop or trusted friend whose day job is computer repair, and ask them to check for unwanted programs.
