Never Turn Off Your Computer...

Ok guys to be able to keep your computer in a good shape and keep running smoothly especially to those who has a brand new computer. What you need to do is keep your computer open from the start you brought it. You can turn off your monitor but not the CPU by this kind of practice life of your computer will be much more efficient rather than turn it off the CPU. You need to burn all the chips of your hardware to be able to see if your computer is perfect. The more you turn off your computer the more risk that you will encounter. It’s like a brand new car that needs to road test! Also the problem will lesser than what you now encountered. I know that some of you guys scared for living your computer on. The reason is maybe your computer will crash if you always turn it on. Well I can tell you, that it’s not true. I can tell you this because it’s already tested. If you have notice in some of the offices in all over the world all of their computer are ON. I think you know that guys. Don’t think about the electricity bill because you can’t spend hundreds for making your computer ON. I have my old computer from 1998 up to present. That computer is always open and never turns it off. The only way he can turn off is if I’m going to reboot it for the reason that I install something (a program that need to restart). And now I have my brand new Dell Dimension 9100 consisting of these specs:

Pentium® D Processor 840 with Dual Core Technology (3.20GHz, 800FSB)
Microsoft® Windows® XP Media Center Edition and Redhat Linux v.9
2GB Dual Channel DDR2 SDRAM at 533MHz- 4 DIMMs
500GB Serial ATA II Hard Drive (7200RPM)
Dual Drives: 16x DVD-ROM Drive + 16x DVD+/-RW w/ dbl layer write capable
19 inch Ultrasharp™ 1905FP Digital Flat Panel
256MB PCI Express™ x16 (DVI/VGA/TV-out) ATI Radeon™ X850 XT PE
Sound Blaster Audigy™ 2 ZS (D) Card w/Dolby 5.1, IEEE 1394 capability
Dell 5650 5.1 100 Watt Surround Sound Speaker System with Subwoofer

This computer has a DSL connected and never turn off.

I brought it 2 months ago now and never turn it off and will never turn it off even if I’m not at home. So far I haven’t encountered any problem in this computer. Warranty of this is 90 days and I don’t have a plan to extend it because I can fix whatever problem it may have. This is how can I manage my computer.

I hope these kinds of practice will help you guys. You can ask some expert too if you don’t trust me.

Peace

PoisonKiss,

You are correct. It is equally correct to say that a computer's life will be extended by turning it off when not in use. See this. There is no "wrong" answer, but rather two right answers.

Your computer's hardware will go a all lot faster leaving it on cuz you could burn out the fan. Then  the CPU will get HOT  and burn itself out and there you wrecked your computer. Also I don't think Dell's warranty will support you if you leave it on cuz that just making the computer parts burn out alot faster then the time they should last by.

As I have said on my previous post…I can fix my own computer. Way back 1998 I assemble my own old computer consisting of:
  1.) Intel Motherboard
  2.) PIII-700
  3.) 256 RAM
  4.) Creative Sound Card
  5.) 2-40gb Western Digital Hard disk
  6.) 2-CD Rom Drives (LG & 72x Kenwood)
  7.) 1 Floppy Drive
  8.) 1-Yamaha RW External Drive
  9.) US Robotics Fax Modem
10.) Creative 4 way Speakers
11.) Windows 98 SE (stable)
All of this hardware are good up to present and still working fine and never encounter any trouble. I was hit lot of a viruses and I can still handle it by myself in a way of formatting my computer. Norton Antivirus is not much more effective and even McAfee. So I decided to use Spyware Doctor & Panda just recently. Now you can see how my old computer was still working even I didn’t turn it off. Ow! Before I forgot you need a good room temperature of course because if your room temperature is bad that’s the time your computer will turn down. Don’t leave your computer ON if your room temperature is not good.
Last year I was working in Saudi Aramco Oil Company in Dhahran, Saudi Arabia as 3D specialist. All computers were using are DELL. And those computers are not turning it off but you need to logoff to avoid someone using it but still the CPU is on. Well I don’t mind it because they can afford. :smileyvery-happy:
Lastly, I don’t want you guys to follow my footsteps especially to those 1st timers of having a brand new computer. I just only want to share my experience and of how to handle my 13 computers.
 
Peace

In this question there is no right or wrong answer. Depending on the usage...........

I like to reboot once and a while, because contrary to what was said above, programs will not completely clean out everything that was written to memory, especially older programs. They will leave small traces. If you NEVER restarted your computer, the small fragments of junk would pile up, and your system's memory would be full of small scant remains of information. For instance, try opening a large application, like photoshop or a game, something of that sort. Time it to see how long it takes to start up. Close it, and time it again. Close it, and then time it again in a half hour. You will see that the later times, it will always be a little faster, because some stuff was left in RAM.

I agree with Rogan completely. Many processes have memory leaks (some well known - others yet to be discovered) and over time will 'eat up' much of the memory. If the process keeps running, the OS's garbage collector fails to reclaim this memory. Moreover if you leave it ON then you are more susceptable to virus and spyware damages. I do NOT have  any AntiVirus on my system and use security schemes and network devices to protect my network . Luckily I have NOT been affected by any, till date (I scan peridically to know) - touch wood! Also leaving on your computer causes the moving parts like HDD and CPU fan to continue to move causing frictional wear and tear, even very little, to take its toll. And ofcourse, switching off your system is environment firendly and saves precious energy resources. If all of us switched off (unlike me ) we could contribute to saving our environment. Personally I keep my systems on to let it automatically update software and patches, and defragment the HDD during the wee hours. Other than this - I do NOT see much benifit in keeping it on. If you are not using autoupdate and scheduled defragmentation settings then it is a better idea to turn your's off. I am a computer technologist by profession, and would love to answer any question, to the best of my knowledge.

I've got a Dimension 8200 that I now use as the home server which has been running 24/7 since new, over 3.5 years ago. Also have a Precision Workstation 650n at work that runs 24/7 for about 1.5 years. They have had no repairs have has never been rebooted except as a result of power failures or upgrades. So it doesn't hurt to leave the computers on all the time.

On the other hand, I have so many systems (server, three desktops in use, and laptops not part of this discussion) I've become aware of their energy consumption, which would run me a couple hundred dollars a year if I ran them all 24/7. So I use sleep or hybernate on all but the server. All Dell systems manufactured recently are Energy Star compliant and guarenteed to work with sleep/hybernate. I use this on a Dimension 8300, Optiplex GX60, formerly on a Dimension 4300S, and an Apple iMac G5 successfully.

A server is different. You are not constantly changing programs, so you the memory leaks that I mentioned in my previous post do not effect anything. My 4100 server is not on 24/7 due to bandwidth concerns at the moment, but I will probably reboot it once a week to maintain top performance.

... and Talmy, I am sure you are Not incorrect. But again, from the hardware's perspective, leaving On doesn't hurt too much. But it does affect from the software viewpoint. And as you all might know, every component is guranteed for a limited lifetime of usage. And this limited time does not count OFF time as much. For example say if the CPU is rated for 27000 hours of continuos cycle, you are extending its life beyond 3 yrs by switching it off when you don't need it. And also the discrete components in the computer like resistors, capacitors, diodes and  transistors will survive longer if rested inbetween operation. Specially electrolytic capcitors which are still indispensible in power supplies, tend to 'dry up' if subjected to elevated temparatures and continuos duty cycles. Also the moving parts like fans can become noisy with damaged sleeve bearings after sustained usage. Though minor, these factors definitely account for partial to complete loss of functionality. Theoritically if your computer survives 5 yrs if left continuously on, then it should survive more than 5 yrs if rested in between - but not necessarily.

Switching the system off won't necessarily extend life because the power and temperature cycling are what tend to wear electronics more than continuous usage. Have you noticed that systems tend to fail when you turn them on rather than when they have been running? Agreed that mechanical components (particularly fans) will last longer if powered down, however the Dell fans are all ball bearing, and mine have been going for 3.5 years without replacement. The cheap white box systems I've had came with sleave bearings that never lasted longer than a year.

Some resistors, diode rectifier, capacitor, transistors, etc. are made in Philippines. There are lots of companies that specialize in the manufacture of electronic chips. The quality of their electronics including the chip’s life is very good. You are guaranteed that it will last long.
Here’s another lesson that you need to think about. The cheaper the hardware you buy, the more risk your computer will be destroyed.
If your hardware can survive in 5-10 years, you need to upgrade your hardware after a few years because of the advances in technology in just a matter of months or a year.

Unless you are into the latest games or have other "the performance is never enough" needs, this is not true. The computer market has been stagnating in recent years because applications have reached a plateau in CPU performance needs. Five year old Pentium III based systems perform just fine for office apps and web browsing. I've even got a 7 year old 400MHz system that still gets used. Even runs XP Pro.
