 |

So yeah my question is, could it be potentially dangerous to leave your computer running for a couple days and nights without it being turned off?
I am running a particular program that works wonders when i'm not around (overnight and when i'm in school).
Thanks

Nope, it's good for it actually. As long as it's not overheating or anything, go for it. I've been running my systems 24/7 for the past 5 years or so, only shutting down to upgrade.

The main reason is for the hard drives, spinning them up and down wears them out much more quickly as opposed to just leaving them on. Once a drive is spinning, it takes very little to keep it in constant motion, but spinning up from a dead stop is obviously much more work.
Also, each time you start the computer it sends a small surge through everything, not to mention the rapid heat change when electronics warm up, wears them out quicker.

just make sure your computer doesn't get too hot and the fan works properly.

I would just say dont give a damn about turning off ur PC
unless following reason
-when ur CPU runs 70%+ while u run ur proggy o-o;;
-when ur CPU/GPU Temp is higher than normal (50"+?)
-if you are going to use ur computer for NEXT 20 YEARS
-if you are running High resource games/proggies/hardware
that eats alot of wattage (EX. Crysis, or running 2x 8800GT+ SLI lol)
the thing is that most ppl switch their sys may be every 2~5years max
so unless you are tryin to use ur computer for decades or unless your
are running out of money to pay the eletricity, i wouldnt bother to
turn off my desktop computer,
incase of a laptop, u might have to consider bit more leaving it on too
long since laptops have limitation of upgrading/fixing it
another thing is to turn of ur INDEXING SERVICE that
XP/VISTA runs on ur background
it swaps ur hard driver even u are IDLE
to turn this damn thing off
push WINDOWS LOGO+R then type in SERVICES.MSC
scroll down to INDEXING SERVICE and DISABLE IT

| No, it doesn't matter how much CPU time you eat up as long as it doesn't toast. Also the temperatures vary depending on make.

Yeah, I would look at it like a light bulb. Almost anytime you have a bulb burn out, it's when you turn it on. It will flicker and pop then die. This is due to the weakness of the filament. Each time you turn on the light, the filament is "shocked" with electricity. On normal bulbs there is no stop from the rush that is sent to the filament which is why normal bulbs don't last long.
After time the filament grows weak that the slighest movement of the bulb will cause it to die, but the shock from turning it on does it over time.
More common electric saving bulbs now a-days have a resistor style base on the bulb that prevents the sudden jolt thats sent straight to the filament and causes it to "warm" up instead of just instantly turning on. I use these in my house and the current one in my room has been in for over a year now and hasn't needed to be replaced yet. 
(I leave my light on almost 24/7 as well.) |
in the old filamant lightbulbs it is the heat expansion and contraction making the seal more brittle due to the stress caused by this the seal eventually cracks and lets air into the bulb filling up the vaccum,
the filament then burns up, melts,
the crack in the seal usually happened the last time the bulb cooled down so the air is already in the bulb when you switch it one to blow the bulb(no puns please),
they are usually graded to last about 1000 hours taken as an average of how often they are switched on and off,
have you noticed if you accidently knock a light bulb that has been in use for a while, the bulb burns out the next time you switch it on or soon after the knock,
thats cos the seal has become brittle due to use and the quite gentle knock has broke the air seal,
you may also have noticed that a table lamp with the bulb pointing upwards, the bulb will last longer as the sealed part at the bottom of the glass bulb is not subjected to the same extreme temperature changes a ceiling lightbulb takes as the heat rises and is lost through the glass instead of the sealed end,
it still has some heat and expansion/contraction stress but far less than the ceiling bulb,
the main risk to table lamp bulbs is being knocked or moved more often,
now that was boring wasnt it

| I'm just wondering how much money it would cost if you let your PC on for a whole month.

yes well I do turn mine off when not using it as a new harddrive motherboard and vid card are usually cheaper than the electricity bill constant running amounts to,
after a couple of years a new cpu/mobo and vid card are usually in the pipeline for me anyway,
my harddrives have lasted well,
even have some second hand ones in use in spare machines that are about 7 years old, even got one ten years old on a shelf that I might drill out for the magnets,
the gaming rig that has a 500 watt psu, now I would not like to leave that on constantly,
I use a lower powered pc with a 300 watt psu for watching films or googling, I dont mind leaving that pc on for long periods when needed but leaving it running unattended seems a waste,
if your running a dedicated game server maybe something like that but not my idea of fun, only would do that from a firms pc that was on all the time anyway 
new harddrives are getting such large capacity for low expense that old ones after a few years are not worth the expense of constant running to avoid spin up/down wear,
500 gig external drives are even not too expensive now,
but thats my preference, turn off as I update pc's every now and then,
with the money I save on electricity bills I can afford to buy new ones as well,
still...its horses for courses, everyone has their own best way and this is just my personal preference
