Have you ever wondered what your computer has to go through when you restart it?
The POST
Sometimes computers will start up so quickly, but other times, they drag, don't they? Well, every time a computer is booting up, it has to go through what is called a POST. POST stands for Power On Self Test and it's just a little personal start up test for every computer to make sure it meets all of the system requirements.
There are actually 10 steps in the POST, with the first one testing the power supply to make sure the computer is turned on and that it meets its reset signal. The second step checks to make sure the CPU (Central Processing Unit) can execute instructions. The next four steps are used to ensure that the BIOS (Basic Input / Output System) and CMOS (Complementary Metal-Oxide Semiconductor) are readable.
The seventh step tests the CPU to make sure it can read all the different forms of memory, like the memory controller, the memory bus and the memory module. Next, your computer's memory is tested to make sure it is operational and that it can be read and written, as well as, capable of containing the POST code. The last two steps deal with the I/O bus and controller. They need to be accessible and be able to write and read from the video system and to read all of the video RAM.
If your computer happens to fail any of these steps, an irregular POST will be recorded. The irregular test is known to you by a beep code and it may often result in you having to restart your computer.

Spyware & Malware
Spyware and Malware can easily be installed on a system without the user's knowledge. In some cases one infection can propagate many more infections by downloading and installing malicious software stealthily in the background.
Spyware and malware infections can make pieces of your identity just a few mouse clicks away for criminals because of the ability of the software to gather and report personal information about you.
