Turning your computer off every night, or when not in use, would seem like it could be a cause for component failure, and it's true that as your computer ages, it's likely to fail when turned off or on. But it's certainly a bit counterintuitive to learn that putting stress on your system when it's young, and under warranty, may be a good thing. Remember the bathtub curve, which says that early device failure is more likely when the components are very young and that as they age, failure rates drop?
If you remove some of the expected types of stress by never power cycling your computer, you slow down the aging process.
In essence, you extend the length of time the device remains susceptible to early failures. This is especially true as your computer ages and comes closer to the end of its expected life. By not cycling the power, you can protect older computers from failure, at least for a while. For new computers, there's the question of removing stress being an agent of slowing down aging, thus extending the time frame for early failure to occur beyond the normal warranty period.
Do what you can to mitigate environmental stress factors, such as operating temperature. This can be as simple as having an external fan such as a pedestal or ceiling fan in the hot months to ensure air movement around your computer system. Use a UPS to help keep voltage surges at bay, and keep voltage levels constant.
Use a normal turn on and turn off-cycle; that is, turn the computer off when not in use during the original manufacturer's warranty period. This will help ensure all components are aged out under warranty to a time frame when failure rates fall to a low level. It also helps to ensure that any failure that may happen will occur under warranty, saving you some serious coin.
Once you move beyond the warranty period, the components should have aged beyond the infant mortality time frame and entered their teenage years, when they're tough and can stand up to just about any reasonable amount of stress thrown at them.
So, new computer, turn it on and off as needed. Teenage to adult, it's up to you; there's no real benefit either way. Depending on your computer and the OS it's running, it may support multiple types of power-saving options. Generally speaking, sleep mode is designed to reduce power consumption while keeping the computer in a semi-operational state.
In this mode, your computer spins down any hard drives and optical drives it may have. RAM is powered down to a lower activity state. Displays are usually dimmed, if not outright powered off. Processors run with a reduced clock rate or in a special low-level state. In sleep mode, the computer can usually continue to run some basic tasks, though not as speedily as in a normal state.
Most open user apps are still loaded but are in a standby state. There are exceptions, depending on your OS, but you get the idea.
Sleep mode conserves power while keeping the computer turned on. Running your computer non-stop is costing you money. As we mentioned earlier, the cost for repairing or replacing equipment can quickly add up. Confidentiality breaches are especially possible if you walk away from the computer without at least locking your screen with a strong password. Below are instructions for scheduling a computer shutdown for those people using Windows Once your computer shutdowns are scheduled, it should be easier to extend the life of your device by shutting it down every day.
It looks like you're visiting from Australia. Would you like to see our Australian site? Here are some other computer performance problems you may fix or avoid by shutting down every day: Driver crashes. Graphics card drivers, printer drivers, monitor drivers and just about any other driver you can think of can crash or malfunction.
I also put my computer to sleep manually if I know I am going to be taking a break for more than 15 minutes. Finally, if you put your computer to sleep every night and hardly ever turn if off, it may be good to at least restart the computer every few weeks.

Doing so frequently throughout the day can decrease the lifespan of the PC. Leaving your computer on does little damage to modern computers.
Additionally, external incidents like dropping the device or unexpected power surges while the computer is on can cause significant hardware damage or preventable data loss. The concern that influences many people in one direction or the other about a regular computer shut down is the risk of cyberattacks.
If you keep your computer online often, occasionally restart the device to clear RAM and satisfy the need to install critical updates and patches. The sample consisted of no less than 1, completed responses per question.
