It can. Most computers will not power on if there is no CPU present. Some may power on but will not boot, and may produce an error code.
a fan
Many computer fans are thermostat controlled. When the CPU temperature gets above a certain point, the fan comes on and runs until the temperature drops.
You don't. Actually it is imperative that you UNPLUG your computer before trying to change your CPU. In addition, you need to make certain that you are grounded before you attempt to replace the CPU to avoid static discharge. Continuing on this from Original poster: I have been told by guides and other sources that you do keep the computer plugged in.
Get a new computer, it sounds like this one is pretty well fudged up!!!!
The function of the CPU (Central Processing Unit) is the heart of the computer. Everything the computer needs to do has to go through the CPU. The CPU tells the computer what to do, when to do it, and how to do it.
CPU stands for central processing unit. As the name implies, the CPU processes everything the computer does and handles everything that goes on in a computer. The CPU is often referred to as the brain of the computer since everything goes through the CPU first. The purpose of the CPU is to read machine language and do what it is told by it. The machine code are the directions on what the CPU should do, but the CPU is needed in order to read this code.
A computer's CPU and hard drive are found in theD. system unit
The CPU is not part of the motherboard but it is placed on the motherboard. The CPU is squared and about a quarter inch square in size. It is placed in the CPU socket. A heatsink/fan is placed on top of the CPU to keep the CPU cool which makes it pretty hard to see because the heatsink/fan covers it when it is in a working computer.
there are different ways to keep your CPU cool, the most common is air cooling. whater cooling is also used much, because its silent.
If you keep your computer ON for 1 Year then the computer doesn't have any effect until you are maintaining the Heat of the CPU and control proper CPU utilization i suggest you to don't used Windows on that pc instate use any linux distribution.
I would have to say the CPU, the CPU is needed with any computer. If the CPU doesn't have a fan or heat sink it'll kill your computer, kinda like your brain
The fans usually connect to the motherboard, but they can connect directly to the power supply unit.
