How long is it safe to leave your PC on for?

No more than 24 hours? Days? Weeks?

The reason I ask is that I am doing some big downloads and even with ADSL it takes ages, so I tend to leave the PC on overnight and when I go to work so it can chug away with the downloads.

Is there is risk of malfunction / fire / component failure? I am using standard components such as HDD, CPU etc They are not specialist "server" type equipment designed to work 24/7. Case temps are a steady 25c and CPU is 49c.

I'm probably more concerned about the PC catching fire and burning the house down when I'm not there to look after it.

I think most people have some worries about the PC catching fire, but I have some confidence in even the dodgiest of computer equipment in my room.

I've just got my hands on a MSI motherboard which has swelled capacitors and that has been running flawlessly for about 3 days. When I finally get round to put it in its case it will be my server and I don't plan on turning it off unless I really have too.

My main machine, and every machine I have had since my 486 has been left on permanently. The only times I turn it my PC off is if I'm stayin at my dads over the weekend and it won't be used, or if I'm messing about inside it ( :rolleyes: obviously, lol)

I've never had a PC catch fire, but I know people who have, and it is quite scary.

I say, as long as your PC has decent parts then you shouldn't have anything to worry about. If you are worried about a fire starting, then perhaps fit a smoke alarm next to the PC. Then at least you would get woken up if anything did happen.

Yeah i gotta agree, i've left computers on for weeks at a time and not had the comp die. The only prob i find is that it slowly gets slower lol. Never had or seen a comp set on fire from being left on lol, damn that must be hot!

i never shut my desktop off. it only reboots when a security patch or new software is installed. its been on a month straight since the last time i had to do either. ive had up to 4 desktops at a time running for several months uninterrupted. i had a greater fire risk from leaving the stove on or from people lighting scented candles

I keep my webserver running 24/7 for about the past 6 months, probably only reboot it like 3 times in that time, and it sits right on a carpet floor. I also keep this computer running pretty much 24/7 except for when I need to reboot it for smoething.

Uptime on the file server at work is 697 days
Uptime for both the DB servers is 267 days.
Only reason they were down is we lost a drive in the array. The UPS was faulty, and the generator didn't kick on. Maintenance forgot to make sure the gas was kept cycled.

I rarely turn my PC off. It's probably only turned off for no more than a couple of hours a month. As long as it's not in an incredibly dusty environment, there shouldn't be any problems. Just check that all fans are clean & spinning every so often.

The only reason I leave it on, is cos I use messenger during the day, and usually have something downloading at night. That and the fact that it's more hassle turning it off than leaving it on;)

oh, and we have a PC acting as our router for the network. I don't think it was turned off once last year, and it's only been turned off this year whilst we've been doing hardware upgrades.

Some of you guys talk in a foreign language.... :confused: :D

What on earth is a HTPC?

What is UPS? Expensive?

As for you guys using servers / pcs for routers etc, I'm assuming that these sort of machines aren't oc'd, have extra cooling (or good) cooling and specialised power supply units?

If I'm doing a nighttime download, I can always underclock / undervolt my PC to lower temps / stress etc

The thing that I'm more concerned about is if the PSU fails - would this automatically shut down the PC?

well, my server just uses the stock intel slot 1 heatsink for the 600eb, it runs very cool tho. I removed the stock hs/fan on the Radeon 32mb, and stuck a big heatsink on it so It can just be passively cooled. My intake is a 120mm fan, almost silent.

uninterrupted power supply

if there is a power failure it keeps things running for awhile.

My computer runs constantly. I have a bit of a problem booting at my overclocked levels. I have to set it back to stock, go into BIOS and overclock, then reboot. I'm fine as long as I do not power it all the way down. I have only turned it off for two thunderstorms and to replace my dead motherboard twice in the last 6 months. I fave only had two lock-ups caused by my TV tuner and reboot only when needed for driver or application installations. Other than that it runs non-stop. I have downloaded many movies. I had KaZaA running non stop for almost 1.5 years downloading movies. I have a library of about 500 now. My other 1-2 of my 3 other computers stay on usually weeks at a time.

I built a computer and gave it to my neighbor. The memory was really cheap and gives me lots of errors during boot-up from a cold boot making you reboot about 10 times befor it comes on, so I told them not to turn it off EVER. It has been on for about 1.5 years now. I'm a bit worried that it will not want to boot up when I add a USB 2.0 card and CD recorder next week (just ordered it for them today) for their digital camera and USB2.0 card reader they just got. The computer is not the best, but it is used almost all day and night (both are retired and their son is a 40 year old deadbeat unemployed bumb who stay up all night playing because they are on the computer all day). The thing cost me $135 to throw together for them for a Celeron 900, Voodoo3 3000, 128MB PC133, 10/100 NIC, 20GB hard drive, 20x CDROM, 250w PS and genaric case. I dumped on Windows XP (like all my other computers) and they got a cable modem. They do not do all the downloading because of the smaller hard drive and no CD recorder (yet), but they are online all the time (or playing games).

If you are really woried, then install a temp monitoring program that can shut the system down if it overheats or a fan fails. Make sure your temps are within a resonnable level and your case is cooled OK. Also with all the harddrive activity, you will want some airflow around the drive so it does not overheat. Heat kills hard drives pretty fast. Nothing fansy is needed and a medium or low RPM 80mm fan works fine. Also clean the dust out every few months.

I might as well reply to this as I just put my new server together last night! :D

Server Specs
AMD Athlon 800MHz
MSI 6340 Micro-ATX Motherboard
256mb PC133 SDRAM
6.4gb Hard Disk (another one soon)
Matrox Millenium 2mb :D Graphics Card
D-Link DFE-530TX Network Card
MicroATX Case w/ 300w PSU (Antec 80mm @ 7v / PSU cover removed to allow hot air from CPU area to flow straight into the PSU)
AMD (Barton) Retail Copper Base heatsink w/ 60mm Delta @ 7v
60mm Fan @ 7v as front intake

It does get a bit warm in there, but nothing to get worried about. It had been running Prime95 all night and when I removed the case cover and touched the hard disk, CPU heatsink or northbridge heatsink, they were a long way from causing me concern. I might mod this case so that I can have an 80mm fan as an intake.

This server will be used as a router, web/FTP server, file storage and acting as a dedicated server for a few games at LAN parties.

Aside from the occassional reboot, my PC at work has been on for about 3 years straight; same for the other 3 thousand people here with PCs. (LAN policy prohibits shutting down, so they can do after hours software updates) Not a one has caught fire, though there are the inevitible failures from time to time.

I'm just wondering, from reading all these posts - what is the power consuption like when you leave a system on all the time? ie what I mean is - if the power supply is rated at 400W, does it draw 400 watts continuously because that would run up quite a bill, or does it depend on how the PSU is loaded...?

As for starting fires, i've never come across that happening but just to be on the safe side put it somewhere by itself where it could not ignite anything else if your worried, and use an all metal case to contain it ;)
