Is this true or a computer myth? - Page 2

post #11 of 21
on whatercooling system shutting down often can cause stress on tubing etc .

but for a normal computer it do nothing . and yeah your pc will become useless before dying .

It's like a tv with 150,000 hours of running time . How will you watch TV on the same TV for 150,000 hours before upgrading.

Myth both ways.

Many believe leaving a PC on 24/7 wears out CPU/RAM/hard drives.

Others believe turning your PC on and off through the day causes your components to expand/contract which can cause wear. Turn it on, the heat expands your chips. Turn it off, they contract back to normal.

Both are somewhat myths. Leaving a CPU overclocked at high volts running at full load 24/7 is sure to cause more wear than normal. I used to never shut down, but now I turn off my PC almost every night just to lower my electric bill.

Leaving it on all the time seems to me like it would wear things out more than turning it on and off often.

But really, what part of turning it on and off would hurt it? There are very few moving parts.
Oh sorry, i forgot to clearly state what i meant by "keeping it on". I have always had an automatic sleep setting if idle for a prolonged period of time. I don't just keep it on 24/7.

My Socket A system is now 10 years old and has been on at least 3 years as reported by my HDDs SMART. I have more an issue of my IDE cables corroding and corrupting data than anything. It's been O/Cd to 2.4GHZ from 1.2GHZ on the stock cooler. Oh, and my CMOS battery died.

I'd be more concerned about power fluctuations as not only spikes but droops can damage equipt over time. On the old mobos with liquid caps they could fail due to age, spikes, or droops since during a droop the capacitors would quickly exert all of their energy leading to heat and stress on the mobo's traces. I'd invest in a voltage regulator or UPS since power quality has more an effect than leaving it on during its useful life.

It would be interesting to know what the military does since that is where the practice of leaving all electronics on all the time came from. Back in the day, even on radios which then used HOT vacuum tubes ("valves" for you Brits) and on which the only moving part was band control variable capacitor, the military ran extensive testing and found that the electrical surges at startup degraded capacitors and heaters far faster than leaving them at a stable condition - On.

There exist today some hard drives that create an "air cushion bearing" upon spinning and others with ferrofluids that act somewhat similarly. Despite the possibility for less than optimum "lubrication" I have read that "constant on", while not detrimental, is no longer an improvement over Off-On in terms of longevity.

Again, I wonder what the military does? They obsess over such testing.

Leaving electrical appliances on when you're not using them is a waste of electricity. That's why there is an on-off switch.

The lifetime of a lot of electrical components (TVs PSUs) is measured in 1,000s of hours of use.
