Never unplug a component while your system is running. Exit all programs and shut down your computer when plugging or unplugging computer devices and peripherals. Ignoring this advice can easily result in a short, therefore damaging either your computer or the device you are adding or removing. The only exception to this general rule is a USB component (like a digital camera) that is designed to be plugged in and out while the machine is running.

Keep your system away from heating and air conditioning vents, radiators, and open windows. This will prevent temperature fluctuations in your system hardware and reduce airborne particles like dust and smoke from entering your system.
