cold start

[′kōld ′stärt]
(computer science)
To start running a computer program from the very beginning, without being able to continue the processing that was occurring previously when the system was interrupted.

cold boot

Starting the computer when its power is turned off. To perform a cold boot if the computer is running, select Shut Down. Once the machine is off, turning it back on performs the cold boot.

If the computer locks up, a cold boot is necessary because a restart ("warm boot") may not be sufficient. A cold boot removes power and clears memory (RAM) of all internal data and counters that keep track of operations, which are created by the OS and applications when they run. Erratic program behavior is often cured with a cold boot, also known as a "hard boot."

Remove the Power
Even when shut down, computers may occasionally retain settings in RAM. The only way to absolutely guarantee RAM is cleared is to remove the power source, which means unplugging a desktop computer or removing the battery in a laptop. Laptops with non-removable batteries are typically cold booted (reset) by holding down the power button for 10 or more seconds. Sometimes another key or button must be pressed along with the power button.

A/V Equipment
TVs, A/V receivers and set-top boxes generally draw power when turned off, and they must be cold booted by removing their power cables to reset them. Contrast with warm boot. See boot, clean boot and hard reset.
