Troubleshooting

Troubleshooting is a source of the problem search systematically so that the problem can be resolved. Troubleshooting, sometimes the removal process is a problem, and also the removal of a potential cause of the problem. Troubleshooting, generally used in various fields, such as in the field of computers, systems administration, and also the field of electronics and electricity.

How to overcome the slow troubleshooting pc

Some things that must be taken to respond to problems "that slow computer!"

1. Viruses and spyware is one of the causes of the slow pc, because the most easily menyusupi and many users who interact with it, spyware can be used to bring from users or from the banners and banner-ads on a web page that when we start off access pages / banners through a browser that has the grip of security that is not good, so that spyware is very close to IE.
Some ways to remove spyware:
a. Identify and analysis process that is running with the windows
Task manager.
b. Identification and non-activate the service through
management console.
c. Identification and non-activate the service on the startup items with the system
configuration utility.
d. Find and delete the entry in the registry, which is in the startup.
e. Identify and remove the file suspicious.
f. Install and use spyware detection and removal.
2. Processor around. Most processors easily generate heat, so that requires a special refrigerator and a special type of fan, so when the temperature exceeds the increased processor, the system will be slowed and the process will be slow. Processor fan that failed due to:
1. Dust that the fan rotation Smooth.
2. Fan motor damaged.
3. Bearing fan, so there is a fan dOLL "jiggling."
Jiggling is if the fan is rotating there is noise krek-krek quickly due to have started bearing fan dOLL.
3. Ram that bad. Some situations can also because of the bad influence of ram, this
due by:
1. RAM timing later than the optimum specification engine.
2. RAM has a value of the minor can only be seen through after some test.
3. RAM is too hot.
4. The hard disk file. If the hard disk often experience failure, this will also aggravate the performance of the computer, and type of file this is the cause, nature can be mechanical, electronic, even firmwarenya not update, this will cause a hard disk:
1. Access time is slow.
2. The number of bad sectors rising in the scandisk.
3. There bluescreen not terjelaskan.
4. Boot failed.
5. BIOS Settings. Usually, the BIOS settings are not dicustom will be slowing the process a few seconds, especially when booting, for that we must mengcustom BIOS settings so that the work performance of the boot process can be accelerated, in general, setting the BIOS that must be considered are:
1. Boot directly to the hard disk.
2. Disable the IDE drive is not used.
3. Set the speed of RAM latency.
4. Turn off the IO / IRQ onboard device that is not used.
5. Use Fast POST.
6. Disk type / controller compatibility. Usually the motherboard now have kontroler good for the parallel ATA disk, but we must consider it an IDE cable, because cable has some certain specifications, there is a udma 33, 66, and 100, if we see a physical, has a fibrous cord of a many fine and smooth, while the udma 33 serabutnya little, so use the cable that has a high specification for the disk us.
7. Windows Services, some of the service must be turned off and if we do not membutuhkanya is:
1. FTP 2. Indexing Service
2. Remote Registry
3. Telnet
4. Remote Access
5. Remote Desktop
6. Automatic Update
8. Process the invisible. Sometimes, we know there are no programs that run only
in memory, when we have not even use it again or we have menguninstallnya program, but there is still running, for that we must consider the process what is happening in the computer we see the task manager, and we can end taskkan or kill, and we can remove. exe it.
9. Disk Fragmentation As the characteristics of the file in a computer must have a process in the file add, in the edit, or remove, it can cause fragmentation in some areas hard disk sector, for that we need to fix the data in the computer, namely the mendefragnya. if we use Windows XP, we can use defrag.exe and meletakannya in the schedule to be running at the time that we set.

How to accelerate the work xp system (Win XP)

Slow computer performance, which often make us irritated. This can be caused by several things diantaranyanya interference by the virus, memory and hard drive capacity, etc..
The following are ways to accelerate Win XP
1. To get the speed work that fast hard disk that has a high speed
2. Use 512MB or 1GB memory to add speed Computers
3. Make sure the system running XP NTFS is not FAT 32. To check whether the computer system running the FAT32 or NTFS how 2x click on My Computer and then select the C drive right click select properties
4. Disable Peng "index" file that was slow work system. By way of the right-click on the C drive and then select 'properties' and then lose a check on "Allow Indexing Service to index this disk for fast file Click." Then, click Apply, and the options menu appears, select the menu "C: subfolders and files" Finally select "Ignore All"
5. Update the driver and the driver computer BIOS
6. In the device manager, double click on the IDE ATA / Controllers atapi devices. Make sure the DMA enabled on each drive that is connected to the Primary and Secondary controller.
7. Scan your computer from viruses and spyware threats. Because the virus and spywre can disrupt computer performance. Do not forget also updates antivirusnya. Do not be too many or more than one to install antivirus software.
8. Eliminate programs that are less useful or never used in the Windows Start menu komputer.Gunakan Up in the run to do it, how to click the Start menu select the run or pressing the button with the windows up window appears on the window keyboard.Setelah run type msconfig and then select the tab Start up and lose a check mark on the program, which is rarely used.
9. Check the system RAM with the software - software that is used to Optimize RAM such as RAM Defrag 2:55, Ram Magic 1.0, RamCleaner 3.2
10. Clean your PC from dust and dirt that stick on pc.Buka also Chasing and bersihin part in the Chasing the dust.
11. To accelerate the loading of Windows, there are some things that can be done. For example, the icon in the desktop and do not use wallpaper that takes a lot of memory. Change the wallpaper with a background color, and use the Desktop Cleanup Wizard that can be found by right-click the desktop icon to clean. Do not forget also, run defrag regularly.
12. Use Files and Settings Transfer Wizard to move files and settings to new computers. How, click Start|AllPrograms|Accessories|System Tools, kemudian jalankan File and Transfer Setting Wizard

How to download data quickly

The Internet when not this technology becomes more rare. Already many people are going to use the Internet and in daily life activities such as offices, business, education dll.Contohnya students who find material pelajarab or school assignment by downloading via internet.Hampir some people use the Internet to download. However, sometimes the download process do we feel old or slow. This can sometimes make us irritated and not patient.

One way to accelerate the process of downloading the software is to use a download manager, for example: Free Download Manager, etc. Star Downloader. When we download the data using the facilities provided on a browser such as Internet Explorer, FireFox Mozila average download speeds of up to a maximum of 5 kb / s. When we mendown; oad several files simultaneously, the download speed will be reduced so that the download is very long. Sometimes there is also a computer error or computer hangs causing death and we lose the data that we are downloading.

With Download Manager, such as the Free Download Manager, the maximum download speed can reach 24 kb / s. Although the "hang" or "error" and closed all sites, the download will continue running (unless the computer shutdown or restart). Because the process of downloading the download manager with a relatively stable and kuat.Download Manager will make the process of downloading the software more quickly, more quickly than used to download other files.

PC does not work (can not run the operating system)

If your PC does not like light, it does not mean that the hard disknya damaged. Check the first power cable, may be separated or who lost electricity. If the electricity flow and fan power supplay have been twisted, the BIOS is also active, but can not go kesistem operation, then there is the possibility of system files that were deleted. If there is a message the signature invalid system disk or missing operating system.
Problems that can be dangerous is if the hard disk from your PC at all I would like to access. Check the first cable data, if the data cable is installed properly and the BIOS can detect your hard drive, then the cause is a virus attack, the mechanical damage, and programs "bad" that set the hard disk, install a different operating system, or program partitions that damage the hard disk, therefore it is prudent to update the virus with anti vurus regularly and do not install the original program.
If the computer still can not booting do not panic, try to check the MBR (master boot record) may be damaged if broken, we can make back with a feature that is diwindows 95, 98, ME or from the antivirus program or another utility, how to enter the disk and type starup Fdisk / MBR.
To reinstate the lost files on Windows 95, 98, or me (not Windows 2000 or XP), switch on your PC with the Windows startup disk, and appear after the prompt A: \, when SYS C: and then click enter. Computer will copy the system to system files from the diskette to your hard disk.
If your application has SystemSuite or SystemWorks, it means that the existing facilities management or recovery disk inside. This means enough to secure your computer from damage to the system

Windows registry problems during the booting

You have a problem (damaged) when booting the Windows registry, which computer you should always check the registry and restart the computer.
Do not make a quick re-install, although how this is the easy way (for engineers lazy) to overcome the problems in the engine windows.
Try to follow these steps:
Start to restart your PC. When the display "loading Windows is shown, press F8 key to start-up menu appears. Select the appropriate number utuk run on the windows Comment from commentsplanet.com prompt fashion.
Comment from commentsplanet.com At the prompt, type C: \ Windows \ Comment from commentsplanet.com \ attrib-h-s-r C: \ system.1 st
This will change the numbers attrib certain files on the registry files stored earlier. Next, type C: \ Windows \ Comment from commentsplanet.com \ attrib-h-s-r C: \ Windows \ system.dat . Mengubagh this will be the key attrib specific figures on the actual registry files.
Comment from commentsplanet.com on Prom type: renc: \ Windows \ system.dat *. rar this will rename the file to replace the existing registry (system.dat) to the other a different name (for example system.dat).
From the command prompt, type: copy C: \ system. 1 st C: \ Windows \ system.dat to copy the registry previously saved and make a registry that is used later.
Shut down and restart the PC. When loaded with good running Windows registry files that have changed, then this shows the damage registry.

How Computers Work

Each time a computer is activated, a process called booting will occur the first time. There are three stages in the process of booting process, namely the CPU reset, Power-On-Self-Test (POST), and the boot disk.
CPU reset
CPU reset is a process that the PC is done first. This is because the CPU is the most important component. Then reset the CPU made the first start for all activities. CPUs are usually triggered by the reset button, power, but can also be done from the network or other systems. After the CPU on the Basic Input Output System (BIOS) are also active.
BIOS work to serve the movement of data include computer information systems But because the input and output are determined. The BIOS can be protected using a password to be able to start work. So without the correct password the computer BIOS will not work. In the BIOS there is a program called Power-On-Self-Test (POST).
POST
Will be testing the basic components of the computer. When the CPU to activate the BIOS, the program's run. The first review by POST is the integrity and the program's CPU itself. Moreover, the program will check the disk's drives, monitors, RAM, and keyboard. At the BIOS POST is active and not yet done, you can menginterupsi booting process and the configuration CMOS.
CMOS is a small memory to store the BIOS configuration and its importance as the media make booting, the processor, memory, and more. Here also saved time and accurate for the dismantling of the computer. CMOS batteries are equipped with a special order data is not lost in it.
Boot disk
Boot disk needed after POST finished because the computer is ready to run the operating system that is very useful for connecting with the human computer. Starting the operating system needed a system that will initiate the beginning combine all functions into one computer and ready for use. This initial system and then stored in the media that the computer can read. This medium term is called the boot disk.
To continue to use the computer, boot disk must be absolutely no any medium. The media which will become the boot disk you can do in the BIOS. After all finished, you are ready to use the computer.
Loading Operating System
After three early into the process, the computer will be using the operating system. As you know, many operating system that is currently circulating, such as the Windows operating system, Linux, etc..
Three important things that must be understood about the operating system is working the way the operating system itself (kernel), file system, and the user interface (shell), and do not forget the applications that run on it.
How the Windows operating system include the understanding of the system account on Windows NT and their families, file access control, registry, system logging, and more. All have the same level of interest, but generally the system registry, and logging is a component that will be frequently seen.
System logging is a component of the computer documentation because this is recorded in the log all the data movement. In the operating system Windows NT/2000/XP, logging stored in the directory "% systemroot% \ system32 \ config \" (c: \ winnt \ system32 \ config \). Log files that are included in the file Appevent.evt (contains records of the application), Secevent.evt (recording activities related to security, including login), Sysevent.evt (record all incidents related to the system as for example, the shutdown). In addition to these files are log files that are available to be observed / views back again.

B I O S (Basic Input Output System)
BIOS program is a program kontroler standard installed in the motherboard. This program is stored in the IC chip called the ROM (Read Only Memory) and always work to control the hardware installed on the motherboard, although not used the computer (turned off). This is made possible by the small batteries that were installed on the motherboard.
People often mention this IC chip with a BIOS ROM IC. At the time it finished, the program must be set in accordance with the types of electronic equipment that will be connected with the motherboard. In addition, each program when the BIOS will always control the hardware installed even if you turn off the computer. Controls currently allows each computer is always ready for use when you switch on the computer. On the condition of weak batteries small, usually peengaturan in the BIOS program is lost, so you make the difficult computer. You must return to reset the BIOS program as you do it on time.
ROM BIOS and consists of several kinds, among others:
- AMI BIOS ROM
- ISA ROM BIOS
- MR ROM BIOS
- ROM BIOS WIN
- Etc.
Usually to enter the BIOS setup mode, such as CMOS BIOS, AMI BIOS, and some other mode BIOS, so when the computer was first switched on, we can press the button del.
For IBM BIOS setup mode we must press the F1 key or F10, while for the BIOS Setup mainboad with Intel Chips that use the F2 key, while for Compaq machines modd old setup, the user must first enter the BIOS setup floppy disks it, so can make the settings desired.
How safe mengotak-atik PC BIOS settings
When Windows is the friendly face of the projects shown to the world of computers, the BIOS is the dark side of the subconscious duty to think. BIOS (Basic Input / Output System) is the code for the fundamental functions of the PC, such as collecting pounding the keys of the keyboard or put pixel to screen.
This small program working behind the scenes, translating commands of Windows, people-friendly become zero and one that is only understood by your hardware. As natural and unconscious people, the BIOS can be very strong influence on the behavior and performance of your PC.
Update BIOS
When new technologies appear and the old bug is found, the computer often publish a version that was updated BIOS that can overcome the problems and improve performance. Check the Web site of your PC manufacturer on the latest update. But first make sure you have the latest BIOS version number; usually appear briefly in the monitor you right after you turn on the system. (Press the Pause when kilasannya too quickly.)
Updating the BIOS easy, but you must do so with caution. Usually you need to run a small program from the floppy disk only. However, when problems occur, you can only mourn the motherboard that can no longer use. So make sure that you have read all the instructions in the readme file update the BIOS, and always do exactly what these instructions say it.
Utility Setup
If the BIOS is unconscious PC, the setup utility is the foundation to build character PC. Utility has settings for the user to control hard disk, memory, graphics cards, power saving, USB port, and other hardware. These programs are usually included in the disk, but is now stored in the chip ROM with the PC BIOS.
Because the setup utility created by the BIOS manufacturer and are in the same chip with the BIOS, this is often called the BIOS setup utility. And because the utility is saving settings in the chip clock / calendar - chip complementary metal-oxide semiconductor, or CMOS - so often referred to as the CMOS setup program. (Chip CMOS batteries have to maintain their own settings even if the PC chip is turned off.)
Setup utility has a drawing of the hardware settings, ranging from the obvious visible, such as setting the time clock in a PC, which is not visible until, as the number of "wait states" that coordinate the flow of data between the CPU and RAM.
Technical BIOS Setup
First thing you need to remember to do before the BIOS setup is not harmful.
When the setup utility to work with a PC, use the same practical instructions taught in the early brain surgery: "If you do not know what you are doing, then better do not deal with it." Carelessness wait to change the state or other settings can reduce the performance or even cause the system to crash.
If you think you've accidentally change the settings when working with the setup utility, immediately stop and start from scratch again. All the setup utility has a menu that allows you to exit without saving changes. You may also see the option to restore the settings to the default values. Ignore this option: If your PC vendor has been doing fine-tune the system, the default settings of the BIOS manufacturer may not make it optimal.

DOS APPLICATIONS

DOS (Disk Operating System) is a program that works to configure a computer that can run as a given input.
Operating system that is commonly used MS DOS, because in addition to the capacity kacil also commands that are used relatively easier when compared with other systems.

Some functions of the Operating system (DOS) is:
1. Organize or control of a computer
2. Memory Set
3. Set the input and output data
4. Menegement file
5. Management directory

A. File processing and Directory

In the DOS operating there Command-command/perintah grouped in 2 groups, namely:

-Internal Command / Command Internal
Is a command that no longer requires a special file, because all the internal instructions have been put in the file command.com

-External Command / External Command
The files have retired and no longer be on file command.com

B. Internal commands, among others:
1. Dir command
Used to display the contents of a directory to the screen.
How writing:

[path]: Showing the list (listing) the contents of the file that is in the path.
[Files that will dilisting]:
The determination of any file that the listing can use the wildcard character(? & *).
? 1 character whatsoever
*: All the characters
Example:
? oba.txt: All files that begin with any letter, and followed oba.txt
try .*: All files with the extensions named try anything.
[/ p] [/ w]: Appearances dilisting the file on screen.
[/ P]: displayed per page (per screen),
[/ i]: displayed sideways, all the files directly.
[a]: All files, including files with hidden attributes, is shown.
