Simple Way Maintenance Your Computer

Maintenance Computer or Computer Care, especially the CPU will usually only be done after the complaint or damage, it is less precise. Computer maintenance should be performed regularly both on the CPU and the monitor. Actually there are some fundamental things that we often forget to do with how to care for a computer or a computer or a PC maintenance tips, which can cause damage to the computer.





Computer Hardware Maintenance section

The concentration of dust on the device in the CPU and Monitor. Especially on computers (PCs) are placed in open space. High dust concentrations will cause impaired peripheral connections on the socket. Also during the rainy season or the temperature of moist dust will absorb moisture and behaves like a conductor who can connect short (surge). It also resulted in an insulator layer on the PCB peeling causing corrosion on copper lines. If this happens, the computer maintenance will be more difficult because there is no way but to replace the peripherals.

Refrigeration, on several types of computers, especially older computers have a processor that is high enough temperature but has a way of cooling which I think is still lacking. Room temperature is ideal for the PC about 19 degrees Celsius


HardDisk space is not proportional. 80GB hard drive size is certainly not proportional if there are only 2 partitions each 40GB C and D. Whereas the use of System C is not more than 10 GB.

Installation of peripherals that are less fit or less sturdy. Usually this happens on a local PC assembly. Often means the installation of Motherboard or other peripherals with screws that are incomplete or less tight. This is often overlooked in how to care or computer maintenance tips. This can be fatal. How to install socket fitting, it also can be fatal.

Power Suply conditions.
It often escapes attention when we take care of the computer. On the use of long, most power supply will decrease power. Power Capacity Power Supply is inadequate and does not use Stavolt, also can damage your CPU componen. Frequent power drop / off or less power. This will cause the computer to suddenly die without process shutdown


Computer Maintenance Software section

Incompatibility of OS, Application, and the volume of data with computer specifications are used.
Frequent use of computers for heavy games. Running games on the PC will generate a lot of space-space fragment and temporary files that slow computer performance

The virus. The virus can lead to slow access to the computer and damage to systems or data. Even in extreme conditions can cause the computer to jam / hang. If its stuck there is no other way than pressing the Restart button on the CPU. This often occurs automatically when the CPU is often die without ShutDown process which means it will shorten the life of the computer hard drive in particular. Usually the virus is transmitted through the stick and the Internet. Besides the selection of inappropriate anti-virus also can affect computer performance.

By knowing the things above, to anticipate needs to be done to care for a computer or  computer / PC maintenance tips in total as follows:

Clean the dust on the motherboard and other peripherals on the inside of the CPU with a paint brush and small to medium-size angle and narrow crevices. Perform well on Power Suply by opening the casing / box power supply first and note the solder-solderannya whether to re-soldering. Or use a high pressure air (compressor) so that peripherals completely clean of dust.

Remove and reinsert the peripheral sockets. This is to ensure a perfect connection to the connectors periphera. just once every PC maintenance.
Remember, Do not use liquid cleaning Contact Cleaner in peripheral connector sockets because of the way is wrong. Fluid Contact Cleaner is very difficult (very long) dry and it makes dust stick easily.

Notice how the installation of motherboard and other peripherals is there a screw is still lacking or lax. Complete and tighten the screw-couplers.

Customize the OS and Applications with the specifications of the computer and do not store data on the hard drive is too big. This will aggravate the performance of your PC

Make a hard drive partition that is proportional. For example 80GB Hard Disk Space Used C with no more than 5GB would be better if we created 3 partitions with 10GB for C, 35GB to 35GB for D and E. Accordingly with access to the System and data loading will be faster.

Do not use the PC for heavy games unless your computer is designed for the Game. If its maniac game, just use the Playstation.

Use appropriate and always Antivirus Update, in the presence of antiviral always update will alleviate or tips on how to care for computer maintenance computer or PC.

Use Air Conditioning to the PC or if not possible can be compensated by way of mounting Coolling Fan Extras when the processor is too high a temperature above 36 degrees Celsius. This happens especially on old computers.

At certain times do Defragment Hard Drive to rearrange the order of the files to your computers performance easier. But not too often ..!

Perform Reinstalling the OS and applications when necessary. Reinstallation thoroughly once in a year its no exaggeration to refresh the entire system. especially if we want a system upgrade. (Eg from XP-SP1 to XP-SP2 or XP-SP3)

Perform the removal or Remove data or application in which if not effectively (never used)

Frequently cleaning the Temporary files, Prefetch files, Chokies files and junk files in the Recycle Bin.

1. The steps to clean Prefetch File:

Log Explorer - Go to C: / Windows / Prefetch - Select All (Ctrl-A) - Dell

2. The steps to clean Temporary Files:

Log Explorer - Go to C: / Windows / Temp - Select All (Ctrl-A) - Dell

After these two steps above do not forget to clean the garbage file2 in the Recycle Bin by right-click the Recycle Bin - click Empty Recycle Bin - Click Yes

3. As for cleaning Chokies files you can use CCleaner Software

CCleaner Freeware Software

4. Using Utility Software for repairing your computer registry

Chokies file2 will appear whenever we connect to the internet. The more we often connect to the internet ... its a good browse, download or upload, the more files Chokiesnya. If you connect to the internet every day, clean the file Chokies at least once or twice a week.

Always Backup the data were deemed important, you can copy and paste on the CD. this is to anticipate at any time if exposed to a virus attack or fatal damage to the Hard Drive

Complete with UPS so that if a sudden power failure there is still time to save data and shutdown the computer

Do not let your computer too long unused (never turned on at all in a long time). At least a minimum of every day the computer is started about 1 s / d 2 hours. This is to warm the inside of the CPU so that the air free from moisture.

Do not expose your computer from shock, vibration and pounding especially when the computer is on, this is very dangerous because it can cause fatal damage

Do not hesitate to call a computer technician to perform maintenance on your computer, if you feel unable to do so.

Maintenance Computer or Computer Treatment in the above can be carried out regularly according to the condition of the computer and its environment. Usually computers that require immediate treatment have symptoms such as access starts to slow down, frequent jams / hangs, often scanning the C drive every time the computer is turned on, blue screen memory, applications often error or do not go according to their functions, and other things that lead users begin to feel uncomfortable with computer performance.

With the computer how to care for a total and expected performance of our computers regularly will always excellent and durable

Function and capacity similar to a fixed disk / hard drive. The difference this device can be taken anywhere, because it includes the Removable Disk. 
Interface: USB


SOFTWARE
Software is a program, device drivers, and files on the computer. Namely;
  • Operating System (OS)
The operating system is the software that controls the performance of the main system. In determining the OS to consider the compatibility (support for programs to third parties, as well as support for hardware), stability (Often Mistake or not), and Price Range (OS Windows XP Home Edition for dollar cost nearly 800ribu, Linux offers a free OS such as Ubuntu). 
Example OS, DOS 6.22, Windows 3.11, Windows 95, 97, 98, 2000 Server, XP, 2003, Vista, Linux Mandrage, Linux Ubuntu, Suse Linux, etc.
  • Program Application
The application program is a supplemental program to support the performance of the computer. (Price Software Microsoft Office Word, Excel Access to 1.7 million). Example Applications, Office (Word, Excel, etc.), Winamp, Power DVD, Pascal, Application Games, etc.
  • Device Driver 
All the hardware described above will not work without a Device Driver is installed in the Operating System. For example, the printer cannot print without a Device Driver. For Exsample : Suppose we want to install a TV tuner card installed in the PCI slot. Once the computer is turned on it will be confirmation that the new hardware found and then the computer asks Device Drivers for new hardware. This could mean that the computer wants to know what the name, the function and workings of the new hardware and ask identifier wheel / in the form of software (usually included in the package tool). After we gave the driver files in the form of software, the computer will know that the name of this tool is the TV Tuner, Brand A, mounted on a PCI-X slot, and so on. However, the operating system has been equipped with many hardware-hardware drivers that are often used in PCs. If we put a new tool to the computer then the tool is ready for use, it is called Tool Compatible. Stay updated drivers so we can work optimally. For example, flash, LX-300 Printer, Monitor.

7 ways to speed up your computer



How to speed up My Computer?

If so, there are tons of simple tasks and hardware upgrades that you can do to get your computer back to running at its top speed. Stop wondering why is my computer so slow. Listed below are 7 super effective ways to speed up your computer.

1 - Identify and remove malware

To start off with youll want to make sure there isnt any hidden malware currently infecting your system. Even if you think there isnt, chances are some type of malware is hidden somewhere in your system. If you dont already have security software installed such as antivirus or internet security, your computer is most likely infected. Malware includes all malicious computer threats such as viruses, spyware, and adware.

Malware can really slow down your computer and you cant identify malware on your computer without the help of a decent security program. To identify and remove malware youll need to run a full system scan using your security program. Once youve removed all hidden malware on your computer, you should also consider setting up an automatic weekly virus scan to run so you wont have to remember to do so yourself!

2 - Uninstall unnecessary programs

The more high memory programs you have stored on your computer, the less free hard drive space youll have and the slower your computer will run. There are most likely at least a couple of unnecessary programs eating away at your computers memory and performance. Even brand new computers come preinstalled with lots of bundled software crap that you really dont need or may ever use. Uninstalling any programs and services that you find unnecessary will really help to clear out the clutter and free up some extra memory on your hard drive.

3 - Eliminate startup services

You may not even realize it, but as soon as you hit the power button to your computer tons of random services and programs launch which you probably dont need slowing down the startup process. If you find yourself wondering why is my computer so slow during the startup process, eliminating unnecessary programs and services from starting up with your computer will do just that. Over time many programs and services are automatically added to the startup list which can tremendously slow down the startup process for your computer.

To eliminate startup programs and services using Microsoft Windows, navigate to the System Configuration window (windows key + R and type in msconfig) and click the Startup tab at the top. In Mac OS X, you can navigate to System Preferences, Accounts, and open LoginItems.

4 - Update device drivers

Every computer has a big list of drivers for every attached or installed device and over time those drivers will most likely become outdated. Most computers dont automatically update outdated drivers making this a separate task youll have to take on yourself if you suspect your drivers are out of date. The quickest way to locate and install the newest drivers for your computer is with a simple Google search including your exact computer model name such as, drivers for HP TouchSmart 1050. Youll usually be able to download a complete driver package including all up to date drivers for your computer model on your computer manufacturers website.

5 - Reinstall or upgrade the OS

You probably arent aware of all the unnecessary clutter that can accumulate over time and really slow down your computer. Sometimes the easiest and most effective solution to regain your computers top performance is to simply upgrade or reinstall the entire operating system. Upgrading to the latest OS edition will certainly provide the most effective speed boost, but reinstalling your current operating system will work just as well to give your computer a fresh start. Ideally, you should first back up only your most important files and documents to a separate secure location such as a flash drive or external hard drive, that way you can safely install the operating system and restore your files after.

6 - Add more RAM (random access memory)

RAM (random access memory) is basically like a turbo kit for your computer and is a physical hardware component that is easily upgradable. If you wonder why is my computer so slow whenever you have lots of open windows and/or programs open, adding more RAM to your computer can certainly allow you to run more powerful programs at once. Although working with a hardware component yourself may sound a little out of your comfort level, the RAM is one of the easiest hardware devices to replace. Since no data is ever permanently stored on the RAM, you can easily swap out and upgrade RAM in your system without worries of losing or damaging data. The more RAM your computer has, the more high memory programs you can run at once and the more powerful your system will become. 64-bit operating systems can support a whole lot more RAM compared to 32-bit systems which typically have a max RAM limit of 4 GB.

7 - Upgrade to a solid state drive (SSD)

If youre still using one of those old fashioned hard disk drives its definitely time to upgrade to something a little faster. Solid state drives are much faster and more powerful compared to hard disk drives because they eliminate file fragmenting, meaning data can be loaded a lot faster and defragmenting the hard drive becomes a thing of the past.

Solid state drives are also entirely flash-based and contain no physical moving parts such as spinning discs or a moving read/write head. With traditional hard disk drives, the read/write head has to physically move around to access data which is stored in fragments. With solid states drives, no physical moving parts are required and you can access and load your data significantly faster. Tip: Installing the operating system directly onto a solid state drive can increase startup performance up to 8x.
