Does turning my computer on and off stress the components?
No, constant start-ups do not damage computer components. It is more cost-effective to shut the computer down when you are finished using it and doing so will reduce wear on your system.

Turn off your computer or, if you can't turn it off, make sure the power management or energy saving features are turned on. Your monitor consumes energy as well – turn it off, too

- Turn off your computer, monitor, printer, speakers, etc. when not in use. You'll save more energy than it takes to start them back up.
- Your monitor uses a lot of energy, so be sure to turn it off. A screensaver does not save energy. An older computer monitor (not the new flat panel type) uses up to 50 per cent of your computer's total energy, so turn it off or let it “sleep” whenever you can.
- Laptops use just 10 per cent of the energy required by most desktop PCs. Laptops require only 15 watts of power, and have extensive power management features.
- Look for ENERGY STAR qualified products when buying new home entertainment equipment. They use up to 50 per cent less electricity in standby mode.
- An ENERGY STAR qualified computer uses 70 per cent less electricity than a model that does not have power management capabilities.
- Unplug battery chargers as soon as the device is fully charged or when the charger is not being used.
