When you format a computers hard drive you will lose everything that is on the drive. Therefore, it is very important to back up anything you might want later. Additionally, if you are going to be formatting and installing Windows you need to make sure you have the discs for any applications or third party hardware you use since you will need to re-install your programs and drivers after re-installing Windows.
A lot of people aren't sure they want to format their drives in case they ruin their system. Simply shut down your computer. now power it up and enter the system Bios. Change boot sequence to boot from CD/ROM (there are other ways to do this as well) Now exit the bios. Have your operating system disc in the drive and some prompts will come up asking you what to do. Simply follow the prompts and put in the discs as it requests. There are often a few different discs. The computer will tell you what disc to put in and when. During this process your hard drive can be formatted, operating system reinstalled and drivers installed. When you load windows for the first time on your formatted hard drive window update will most likely have a lot of updates to do. just let it do its thing. Any viruses or problems your computer had that weren't to do with its internal components should be fixed. You can do this in about an hour if you know how. Sometimes it takes longer though.

Parts of a computer
Computers are made up of many parts working together. It is not as simple as the cords you plug in when you buy it. Inside the case there are many components that make the computer work how it does.
The Central Processing Unit (CPU) is the "brain" of the computer system . Everything that a computer does is overseen by the by this "brain".
Then there is memory which is very fast storage used to hold data. It is required to be fast because it connects directly to the CPU. There are several specific types of memory in a computer. 3 types of memory are Ram, Rom and Bios. *Ram is random access memory; It is used to temporarily store information that the computer is currently working with. *Rom, which is read only memory is a permanent type of memory storage used by the computer for important data that does not change and *Bios A type of ROM that is used by the computer to establish basic communication when the computer is first turned on.
The motherboard is the main circuit board that all of the other internal components connect to. It is a rectangular circuit board with different kinds of connectors for different components. The CPU and memory are usually on the motherboard. Other systems may be found directly on the motherboard or connected to it through a secondary connection. Sound cards can be built into the motherboard or connect to a PCI slot.
Then there is the hard drive. The large-capacity permanent storage used to hold information such as programs, pictures or even your music.
The oporating system is often referred to as the OS and is the basic software that allows the user to interact with the computer.
Then theres are the graphics and sound cards. the sound card is used by the computer to record and play audio by converting analog sound into digital information and back again. This translates image data from the computer into a format that can be displayed by the monitor. And the graphics card is what translates image data from the computer into a format that can be displayed by the monitor.

What is the difference between SAM and RAM
Ram and Sam are opposites. Ram is random access memory and Sam is serial access memory (SAM). SAM stores data as a series of memory cells that can only be accessed sequentially (like a cassette tape) . If the data is not in the current location, each memory cell is checked until the needed data is found. SAM works very well for memory buffers, where the data is normally stored in the order in which it will be used (a good example is the texture buffer memory on a video card). RAM data, on the other hand, can be accessed in any order.
