I prefer to leave it ON But...

I have been told to at least shut my comp down once a week. Why? I believe it is helpful in correcting and reorganizing features in the background. Such as Scan disk, or defrag., I believe are helped with keeping your computer running smoothly. Don't really know the correct answer for this GREAT Issue. But I have to assume that shutting down your computer daily does disconnect you from your internet connections, which if being hacked, I would assume will help. Other possible pros whould be refreshing your connections with your PC.

A couple of good points not to be overlooked!!!

A couple of good points not to be overlooked!!! see the other Thread titled COMPUTER KEEPS REBOOTING NEED HELP... by GRANTIMAN.

This is another potentional issue if you leave your computer on all the time, Guess WHAT?!!! you should hopefully be cleaning the inside of your computer more OFTEN. Otherwise issues such as the many that are explained in these threads become a problem down the road.
POWER SUPPLY clogs up with dust and pet hair. Results in--Power supply overheats needs to be replaced.
Circuits overheat and can fry if circulation is not working.
FANS, FANS, FANS, need to be kept clean.

If you leave your comp on all the time you run a risk of having a problem with your computer that you are unaware of since you where out and about, but didn't notice all the error messages that kept popping up while you where gone.

How about a category for "Doesn't really matter much either way"?

That's where my vote goes.

Talking On/Off

I was a field engineer on medical systems and we did a service study. We found in the short term that systems left on 24hrs/day had less down time than systems that were turned on/off each day.

I believe in the long run, all parts ie hard drives etc have a MTBF (mean time between failures) number in hours and If your system is left on 24hrs per day for a year you have put over 8000 hours on your hardware. With modern electronics, some with 50,000 hrs MTBF that is still over 6 years before a failure might happen. By then you probably would have replaced your entire system due to technology lag.

I guess it comes down to do you want to pay the electric company for those hours your system is on and not in use.

Older versions of Windows (Windows 95, 98, MyEnemy, NT) bog down after a while and run sluggishly. To a lesser extent this also effects Windows 2000, although not nearly as much as it does the other versions.

Windows 95 and 98 (and possibly MyEnemy) also eventually run out of resources because there is no means to free them when a program finishes.

It is recommended that you reboot the above operating systems (not including Windows 2000) at least every few days, if not daily.

Windows XP does not have any of these problems and can run for weeks or even months without it's performance degrading.

Other issues to consider are energy. A computer that is turned on uses more energy than one that is turned off. The various sleep states are good at conserving energy, but not as good as turning the machine off.

There is also the Internet issue. A computer that is turned off cannot be hacked. One that is left running and connected to the Internet can be hacked.

One of the points often made for leaving it on vice on-off has to do with the expansion and contraction of materials (usually the mother board itself) with the warm up-cool down cycling when you off-on. Supposed to contribute to premature failures over time.

Thanks

My system stays on except when there's a thunderstorm. I'm just too lazy to wait for a bootup. Been running that way since my last upgrade in February 2003. I keep it patched & behind a firewall.

Just cleaned out the dust a couple of weeks ago (shut it down to setup my new desk ). Very little dust. The dust issue depends more on the environment the PC is in than how long each day it's on. Also, a PC sitting on the floor gathers more dust than one up on the desktop.

I've got several friends that work on computers... Network engineers, etc. I used to turn my computer on and off every day. One of my buddies said I was crazy and that servers stay on 24/7 with no problem. He said something about it being actually harder on the bearings in the hard drive to keep turning it off and on all the time. Laptops are a diferent story since they are more prone to heat issues.

Many years ago... I started keeping my computer on 24/7, except during thunderstorms and when were are away for vacation. I have it set to "always on" in setups so that the monitor goes off after 20 minutes. Yes... It probably adds a little bit to the electric bill... but the monitor is what really sucks the juice down.

My prior computer stayed on for 3 years, 24/7... and it was replaced by a faster model. I gave it to my Brother-In-Law and he still has it working... Keeping it on 24/7. My Newest Dell (4yrs old) has been on for the past 4 years with no problem.

Just my .02

I have a friend that has 2 computers that are on all the time. Every once in a great while, one of them need something & he'll bring it over. Since I know what it's going to look like, I'll take the covers off, put it on a cart, roll it outside & hit it with air. The neighbors probably think that a thunderstorm is coming; it's an unbelievable amount of dust.

It looks like from all the posts that a computer is like a car. You have to do some basic maintence at least once a year. I'll bet many problems are related to lack of TLC.
I'm kinda splitting my on/off times with my computer. Shut down overnite and start up during the waking hours and leave on all day.
Thanks again

I think the question here is, why are you asking?
Are you trying to save power, or are you concerned about the system getting sluggish?

Heat cycling is probably the biggest 'wear' from turning the machine on and off.

Clearly, turning it off will save power, a few hundred watts, TOPS, even if you have a massive machine with 600w power supply, 4 hard drives, etc.

As long as the software you are running (be it on 98 or xp) is coded well, the computer can run for a very, VERY long time without needing a reboot.

My home server has been up for 60 days, last reboot was to make some hardware changes.
Many commercial servers run for years without a reboot.
But, these machines run a set of specific software titles that don't get loaded and unloaded all the time.

If you run a variety of software, it doesn't hurt to reboot about once a week or so.

my system is pretty basic. No great computing. My concern was/is "wear and tear". Running unneccesarly when sytem is not being used seems to me counterproductive,however,cycling on and off when you want to use the computer strikes me as too much to ask the hardware over a period of time.

The first part to fail from leaving the machine on all the time will likely be a fan. If your video card has a fan on it, it will probably go first, as they tend to be of lower quality bushing type rather than ball bearings.

If you have a CRT monitor, it will probably be the first part to fail from being powered on/off.

The only machine I ever cycle power on is the notebook. The rest stay on 24/7, but with the energy saver of the monitor turned on (all LCD's), to save hours on the backlight.

In all the years the only parts I've had fail were oem fans (then upgraded with ball bearing fans), one hard drive (a western digital, replaced under warranty) and a CRT monitor that self destructed when it was turned on.

If you do leave it on all the time, make sure it has temp/fan monitoring with auto shutdown.

I leave my computer on 24/7, 365 days a year. The most recent system I built is a hot beast: AMD FX-55 with ATI X850XT PCIe video card (best at the time, still not bad today).. I dont think I have to mention the rest. I've had the computer running without shutdown since I built it 6+ months ago. Not to mention I've built my own computers for past 5+ years and never has one failed one me, all of which were left runnign 24/7.

Wink

Thanks to all for the inputs. I guess it all boils down to personal preference.
Thanks again.
