The continuing technological advances are also leading the proliferation of illicit activities that could call “crime” and are acts that often go against the confidentiality, integrity and availability of computer data networks and computer systems. This is an added difficulty for law enforcement because electronic evidence can be quickly removed or lost, making prosecution more difficult. Therefore, we need a way to rescue and preserve this data quickly.

The computer forensic evidence is collected and used to illuminate computer-related crime using techniques and technologies. Computer Evidence team uses these techniques to discover evidence in any computer storage device such as hard disks, backup tapes, computers, laptops, USB memory, files, emails, etc..

Computer evidence in working to discover fraud, unauthorized use of computers, violation of confidentiality or company policies, inadequate investigation of computer use during business hours, chat history, file and web browsing or any other form of electronic communications, unauthorized access authorized to computer systems, theft of computer data, computer sabotage, identity theft, child pornography, and so on.

All this is done by forensic investigation, expert computer, data recovery and secure deletion of data, among others.

In addition, computer evidence solutions offer computer disaster prevention, backup systems, contracts preventive data recovery, and a comprehensive advisory service and consultancy in computer security issues.

Since the start button is pressed the computer until Windows is ready for use takes a certain amount of time.

The start of any computer is divided into three main stages

1 – Load BIOS and initialization of hardware devices connected to main

This is the stage that usually takes less time, falls since the source powers the motherboard, the BIOS is activated which makes a number of subroutines and initialization test devices up that if any error is not handed over the command to starting sequence operating system.

To reduce the time spent at this stage it is necessary to enter the setup or motherboard setup, that in most cases is done by pushing the delete key during POST, but varies according to the manufacturer, however in the first message shown in display key information necessary for it.

After accessing the setup is achieved in the following search options.

In the configuration of the boot sequence or boot device set as the primary hard drive and no optical drive and comes with most modern computers, in case of future need to reinstall the operating system we will have to back this step that can start an installation disk.

Enable cases to be possible to copy the BIOS to RAM, it greatly speeds this time.

2 – The second stage is the kernel of Windows loading and all operating system processes.

This stage is crucial, it is necessary to implement the following measures.
