  • OT - What happens when you let your computer run a long time?

    Off topic but likely of interest to the members here.

    I would like someone(s) discuss what happens to a computer when it is left running for a long time both hardware and software wise.

    What prompted this request is that I notice that if I leav IE running for a few days it gets VERY VERY SLOW.

    But again the general subject of what happens when one lets a computer run for days, weeks, years? would be of interest to me and others also.

    Thanks

    My computer stays on for weeks at a time. The only time I shut it down is when I do a system scan, or update. But I always log off of the Internet when I'm done surfing the web.
    I haven't had any issues as far as slowing down, or anything else by leaving it on.
    My electric bill's probably a few bucks higher though.

      Two separate things - long runs of computer vs. long runs of IE.
      If some application gets slow maybe it's got some buggy leak which is the cause of it. If you don't have IE open, do things slow down?

      Hardware-wise, if I leave my computer on for a long time I avoid some wear and tear: hard drive spin-ups and thermal cycles on the CPU.
      Also, I don't have to wait for it to boot up.

        According to the engineers at work, if you leave a computer on for days at a time and it starts to act up the first thing you do is reboot. This supposedly flushes out the cache memory.

        I've heard the average harddrive is good for 10,000 hours before the the bearings wear enough that data can get screwed up when reading it. That info may have changed over time.

        If you are running IE8, try going to Google Chrome instead. I just did this yesterday and it solved my crawling speed problem. I got this info from a friend. I google'd IE8 and found this site.

        Thank you to our families of soldiers, many of whom have given so much more then the rest of us for the Freedom we enjoy.

        It is true, there is nothing free about freedom, don't be so quick to give it away.

          My Mac G5 has been on continuously since I bought it four and a half years ago, serving both my Web sites in addition to being used for my regular computer stuff. Haven't noticed any degradation of performance

            Usually what happens is your system gets bogged down running a bunch of useless programs in the background. I leave mine on for long periods of time, but I keep an eye on my process manager and make sure I don't end up with a bajillion useless apps running in the background

              My dell pc has been on for 6 years, I have left it off now for the last few years because I have been on laptops. But it still runs fine when I turn it on.

                Heat is the enemy, if the computer stays consistent running temperature, all is good. Too cold is just as bad as too hot. I wouldn't leave a laptop on 24/7...

                  I have two simulation machines in my office that I keep pegged 24/7. One is running XP and has an uptime of 9 months. The other is running Win 7 and has been running 3 months straight (I rebooted it to install Win7). As long as your apps are well-behaved, you won't have a problem, and even if you have ill-behaved apps, Vista/Win7 now contains almost all third party software in user-space, so they won't take the kernel down.

                  As far as energy concerns, all x86 processors have extensive power management features that are supported by Windows and MacOS. If you're really concerned about power, set your machine to sleep after an hour of idle, and suspend to RAM (S3) after 2 hours. You can also set a timer to power off the hard drives and/or monitor after N minutes.

                        When I lived up in Peterborough, a fellow where I worked had his house burn down. The forensic fire specialists said that his daughter had left her lap top turned on in the basement, and eventually the fan in it burned out and the resultant heat build up started a fire.---The house insurance refused to pay, saying the fire was caused by negligence!!!!!

                          A poorly written app like IE, which has memory leaks, is no indicator that anything is wrong with the computer if it misbehaves when left running. I expect IE to self destruct after a while...so far it has met all my expectations.

                          I have computers on a UPS that are never shut off and they have been running continuously for the past 8 years. Sure they have been rebooted a few times but never actually had power removed from them.

                          We have hundreds of machines up for 3+ years without rebooting.

                          The only issue is that when power goes out and things cool down, it is always an unknown if it will boot again. Hard drives can fail to spin up, power supplies and mother boards may not function, etc.

                          The only time my home machines get turned off is when I lose power. Been that way since I got my first computer.

                            If what I've heard is accurate, another friend tells me when the bearings start to go out of tolerance that you can simply reformat the drive?

                              If you are leaving IE open, it may be filling up its cache. That will slow down IE in general as the default size is ridiculously large. I set the cache at anywhere from 1MB to 10MB for home machines.

                              Another factor would be a memory leak in IE, already mentioned. This could slow the machine down if not kill it.

                              Another possiblity is that your memory is being filled with zombies while you sleep
