Computer Info

Are you planning to buy a new desktop computer? It is certainly a daunting task as options are available in plenty and most of the times we get confused which one to go for. There are many renowned companies that offer computers of different configuration. Prices of computer also vary depending on the configuration. But before buying, you must consider some important things. You can also consult a computer services company to get some detailed information about what you should buy.

Following are some of the most important things you should take under consideration before buying your desktop computer.

‘Your Budget Computers are available of different prices and you must consider your budget before buying. And in this context you should also consider your purpose of buying the computer. For instance, if you just want to check mails or want to surf internet then you certainly should not opt for a costly computer with high configuration. But if you want a computer for software development or for multimedia task, you need a technologically advanced computer. For buying a simple computer you don’t need to spend huge amount of money while for a technologically advanced one the cost will definitely be on the higher side.

‘Hard Disk and RAM These are two most important component of a PC. Hard is the part of the computer where you will store all the data. So, if you would like to store a large number of data such as pictures, music, movies or software programs, then it is always recommended to go for a computer with high storage capacity. The RAM plays a very crucial role in the processing speed of the computer. If there is a good capacity of RAM in your computer, the PC will run smoothly.

‘Computer Hardware There are also other computer hardware as well such as monitor, keyboard, mouse, graphics card, and speakers, etc. depending on your requirement you should buy all these components. For example, if you want to play a lot of computer games, then you should go for a gaming mouse and multimedia keyboard. Now wireless mouse and keyboard are also hugely popular. Although, these components are costly but for maximum satisfaction, you will certainly be ready to spend some more bucks. Monitor is another very crucial part. For multitasking, dual monitor configuration is the best choice. There are various renowned brands.

‘PC Security Do you want to use your PC to surf internet? If the answer is yes, you must think about PC security. There are countless viruses, spyware, malware, adware that are developed by the hackers to sneak into your computer and steal your personal information. So, you must install high quality anti-virus and anti-spyware programs for protecting your data. There are also many computer help provider that offer antivirus support to the computer users so that they can enjoy hassle-free and secure computing.

These are some of the most important factors you must consider before buying computer. While buying computer if you keep all these things in mind, it will certainly help you to get the best one.

What is a Computer Virus? Computer viruses are unwanted computer programs that can invade your hard drive and cause many different types of damage. Usually viruses are created when someone writes a computer, and malicious software embedded within that program. Once people start downloading the program on their computers infected, the virus finds its way in and change negative information stored in computers. Not a computer virus is similar, there are millions of different programs that cause different amounts of damage to a computer. Like human viruses, computer viruses spread rapidly once they are created and computers are exposed to the “infection”. Although instead of traveling by air, computer viruses spread across the Internet, sometimes you can get a virus just by clicking on a specific Web page. Many times computer users have a virus in their computer for a long period of time before it is discovered and before it begins to cause greater damage. Even if your anti-virus software on your computer, it will not always find the virus because the anti-virus software can only find known threats already using a database of that program. You may ask, why would anyone counterproductive for such programs? Well, there is no exact answer to why people aware of computer viruses other than a kind of revenge or to put their skills challenge. Nobody will be able to get these people to prevent the creation of viruses and other computers exposed to infection, the best for computer users to make this invasion to prevent the current anti-virus software and be careful about what sites they visit and what files they download. If a virus finds its way into your computer, it will hide on your hard disk and proliferate, as do cells the virus in humans. You can not tell, but each time you save your data, you also save the virus. Soon enough, the virus multiplied to such a degree that the damage to your data and large problems. Although the computer ROM (Read Only Memory) will not be affected by a virus, the RAM (Random Access Memory) your computer disks and certainly damaged. So if the virus is only in the RAM data in your computer when you shut down the virus will be lost if any memory that had occurred in the random access memory (RAM). Unfortunately, the computer virus on your hard drive or computer disk will remain in your computer after you restart and it will be there when the program again. If you switch from the infected program to another program without shutting down the computer, the virus then the other program. As that happens, the virus slowly by infecting all programs on your computer before an idea that your computer is infected. Currently, millions and millions of dollars spent on attempts to protect computers against viruses and eliminate destructive virus programs. Anti-virus programs are offered by commercial and shareware sources were only made for detecting and programs that may be contaminated with the virus are fixed. These programs should be used to scan for viruses every time you drive in your computer every time you start your computer.

If your computer comes with elementary memory, then definitely you need a memory upgrade. There are different types of computer memories; and every memory has its own distinct functioning. In general, a computer memory has four prominent characteristics namely, volatility, mutability, accessibility, and address-ability respectively. The performance of a memory is therefore based on these virtual characteristics.

The volatile or temperamental memory is the emotional computer memory, which functions in a similar manner human emotions work. As humans have vacillating emotions and so does the computers volatile memory. Volatile needs constant power supply. If theres no power, then theres no volatile.

The dynamic and static computer memories are part of random access memory or the RAM. Both are volatile in nature, and need constant power source altogether. Dynamic memory refreshes itself after regular intervals of time, whereas the static memory doesnt refresh itself. The mutability characteristic of a computer memory is meant for reading and writing storage files, and come as immutable and mutable types respectively. It is extensively used for both secondary and primary storage purposes. ROM is a classic example of mutable and immutable storage memory which is quite crucial in writing on CDs, DVDs etc.

Sequential computer memory works great for off line storage purposes, as it is slow and all the information is gathered and accessed in a sequential order. Accessible is quite common in RAM as well as sequential memory, and gives an access to the stored files, which seemingly appears as instantaneous.

Lastly, the address-ability characteristic of memory is in three forms namely location, file, and content. For fast computer operations it is very necessary that you go for regular memory upgrade. If you are not upgrading the memory from time to time, then you are losing heavily on your computer efficiency. Memory can be purchased from third party vendors, but make it sure that you get original memory and along with the warranties, or else, in case of any technical fault, youd be at the problem end.

No doubt computer has made our lives easier manifold. Though the online activities are endless, computer problems are always bound to be there if you have a system at home. Some may be easy to solve while other types of problems may not be a bit difficult to attend. The annoying thing is sometimes you may not know the exact reason for the problem itself.

Computer problems can be classified as two types:
Hardware problems
Software problems

The hardware problems are related to the physical components of the systems while the software issues are related to the ms windows, driver errors, modem issues etc. Given below are some of the common computer problems and their possible solutions.

Computer Problems due to Power Outage
The intermittent power cuts and voltage fluctuations may cause problems to the computers and disrupt your work. If there isnt adequate power back up for your system and if it gets switched off due to sudden power outage, then it may cause temporary or permanent loss of data, hardware issues etc. The best way to combat computer problems due to frequent power cuts is installing UPS (Unlimited power supply) for your PC. Even if the power goes off, the UPS will give you about 15-20 minutes of power backup. During this time, you can save the programs in which you had been working on and comfortably shut down your system without any hassle.

Drop in system speed
Most of you would have faced the problem of your system being dead slow in responding to commands. Sometimes, the system might take several minutes to execute an operation for what it should have taken only a few seconds. Slow system performance can be one of the most annoying computer problems. In such a scenario, be sure to check whether there is enough space in the hardware and also if the RAM memory is more or not. If you have stored any necessary files or folders or large videos and forgot to delete them long back, then you may get rid of them right away without wasting any more time. Perform disc defragmentation and disc cleanup to create more system space. If necessary, upgrade your RAM and hard drive for better system speed. Do the above steps and be surprised to find at least 40-50% increase in the system speed.

Speaker issues
Dejected that your speaker didnt produce any sound when your favorite song is being played on? Dont worry; this can be sorted out easily. Check at the back of your CPU whether all the wires from the speaker are plugged properly in the appropriate places or not. It is very common that the wires may be in loose contact. See the color of the wires and plug them into the right holes and make sure there isnt any loose contact. Once everything is perfectly done, then start enjoying your favorite music as you wish.
Computer producing Strange Noise
Note that the noise problems are completely associated with the hardware parts of your system. In such a case, switch off the system and unplug the power supply. Remove the CPU box and clean it and allow it to cool down for some time. Now reassemble the parts and make sure there isnt any lose contact. Your system is ready to go noiseless!

Computer Reboots Itself frequently
If your system reboots itself over and over again, then check whether there is any fault in the hardware connections or not. Sometimes, low voltage and power outage may hit the CPU and cause the system to reboot frequently. An ineffective cooling fan at the back of your CPU could also cause such a problem. Clean the fan whenever it is covered with dirt. Place your system in a cool area in your home, preferably near the windows as the system needs cool air to prevent from getting heated up.

Here is a list of the things that to do to keep the computers running at peek performance:

1.Always keep your antivirus program up to date and scheduled to run daily at a time when your computer is on, but not in use. I have been using the AVG free version for many years and highly recommend it.

2.Run the free Adaware from Lavasoft weekly. It is a spyware removal program, with paid upgrades available. Adaware removes spyware, dialers, Trojans, browser hijackers and much more. It is best to remove it all regularly since even the less harmful stuff slows your computer down and wastes space. The free version of Adaware will remove most spyware and does not take very long to run, so I run it first.

3.Run Spybot. Spybot is another free spyware removal program. It will often pick up a few more nasties that Adaware missed. This program takes a bit longer to run than Adaware but is worth it.

4.Clean out junk files (temporary internet files, cookies), remove invalid registry entries, another check for spyware, defragment your hard drive and RAM and optimize your startup menu. I use a program called System Mechanic by Iolo Technologies. I bought this program for around $25 not long after Windows XP was released in 2001. I still use this product regularly. It performs these tasks quickly and is very user friendly. This product is a must have and a bargain in my opinion. I am sure System Mechanic has made many advances in the last seven years, but my old version still works very nicely for me (until the custom computer shop I use quits selling computers loaded with XP!).

This may sound like a lot of work to do on a weekly basis, but is well worth it. I do this on Sunday evenings when I am usually lounging around the house watching TV. I set a program to run, check back in a while when it is done and then start the next one. This way, it is not that much of an inconvenience.

See ya. Gotta run over to Dads now to clean up his computer.
