All the time you have a pc on you eat in to its operational lifetime and stess the components die to heat. Its something to think about.

speaking from an electronic engineer prospective, by switching your PC your components especially the surface mounted components on your motherboard will be effected by the heat and they do expand.
If you keep shutting down your pc and turning it on, by expanding and cooling off, the metal structure would break and it would cause a component failure.

of course the above depends on the quality of your machine.

as long as you're behind a firewall and have a good surgeprotector then leaving it on is the best.

i've seen (in very rare occurences where there are specific weather circumstances) pci graphics cards, that weren't secured properly, work their way out of the slot enough to not work due to the expansion and contraction of the card. like i said...rare occurance

I leave my desktop on all the time, component failure don't really occurs, but it definitely depends on your PC's component's quality. Now, laptop is a bit different. Sudden temperature rise and drop is never good for your laptop, so if your laptop is running at high temp most of the time (above recommended temp, 55 deg C), then it's better to let it shut off at night, I think. However, it may also be better to just let it hibernate, which lowers CPU temp, while you are not using it. Something to think about:)

Good Luck!

Best,

Such extreme stress would only occur if you were turning it on and off repeatedly over short period of time. Your hardware will last longer of you turn it off at night. Also the components that heat up and expand have had this taken into account during its design and sockets etc are designed to be able to handle this slow expansion and contraction, it is only during rapid expansion damage could occur. Also its all plastic now which will return to its original shape if pushed out slightly and the expansion is very small. Its 2005 not 1955 either way its not going to break it but the experts have been saying shut them down for years.
Its also a fire risk and even though its unused a computer still uses alot of power and it is enviromentally irresponsible to leave them on, and expensive.

My few cents ;)

During the heating season (Labor day thru Memorial Day in my neck of the woods) I leave my desk top computer run 24/7. I figure its 100% efficient as all the waste heat goes to heat my house anyhow.

I have a broadband router between my PC and my DSL modem, and I switch the router off whenever I'm not at the computer to make it a little safer from the internet. I also have it setup to do the AV scans and backups at 4:00 AM automatically. I don't have to think very much about doing them manually.

On the other, during the summer I shut it off at night to keep things cooler in the house, and then have to do all those scans manually.

I agree with folks who worry about the repeated heating/cooling cycles. But I also thinks its kind of a moot point. Good QC and good design has left the desktop environment, and all we can buy today is different grades of commodity junk, never intended to last beyond a couple of operating system releases from MS.

I've been through more than a dozen computers and they have all died from planned Intel/Microsoft hardware/software obsolescence rather than any particular hardware failure.

Gotta love em. The alternatives are generally not legal :tazz:

I never leave my Desktop or Laptop on overnight unless I fall asleep and forget about it. Even if I go out somewhere during the day, I shut them down.

I'm an engineer and to tell the truth, in my ~26 years of being around computers, I honestly think it doesn't matter one way or the other.

I just can't see leaving them on all the time.

Correct me if I'm wrong but there is absolutely NO CPU temp in hibernate !!!! The CPU does not work in hibernate...I mean = to room temp.
