Why is my computer running slow?

The modern consumer PC is a complicated beast. Unlike a relatively simple machine such as a lawnmower or a stereo, computers have numerous points of failure that can inhibit or completely restrict proper functioning. Occasionally, a piece of hardware like a failing hard drive or faulty RAM modules are the reason your computer isnt humming along like it used to when brand new. However, its far more often a software issue related to your operating system thats slowing down the machine. Whether you run Windows, Mac OS X or Linux, a little software optimization and house cleaning goes a long way in prolonging the life of any PC.

Due to the mind-boggling complexity of todays computers, good Computer Diagnostics tools are essential for the safe operation and long-lasting life of any machine. For instance, the Windows operating system has a few quirks that, if left unattended, can lead to a slowdown in performance over time. Dead-end shortcuts and links pile up over time, using up valuable disk space, leading to disk fragmentation and overall hurting responsiveness and usability. In addition, errors within the Windows Registry as well incorrectly deleted programs can lead to other important programs crashing. Without a Diagnostics Tool to tell you exactly whats going on, you have no real idea whats wrong with your PC when speed and performance issues occur.

As such, comprehensive Computer Diagnostics software is of paramount importance when it comes to getting the most out of your PC. Most technically savvy users possess the ability to manually tweak settings, schedule maintenance tasks, change startup programs, and troubleshoot issues that may crop up. Unfortunately, that ability to diagnose computer performance issues on the fly can take years of experience and learning, and we dont all have the time to become certified repair specialists. Specially designed Computer Diagnosis software gives ordinary users the ability to speed up their PCs by repairing malfunctioning programs, getting rid of unnecessary files automatically & choosing which programs should run on start up.

A dependable Computer Diagnosis software suite can do most of the heavy lifting for us normal, everyday users who dont possess a Computer Science degree or the gift of feeling out bugs in our operating systems. When choosing a Computer Diagnosis tool, reputation and track record are of the utmost importance. Youre placing the health and longevity of your valuable computer in the hands of a third-party program, so you want to be sure that you opt for a Diagnostics and Analysis application thats time-tested and reliable. Dont just spring for the first free-ware service you find online. Thoroughly research the available options when buying a PC optimization software, and your computer will thank you in the long run.

Many people relate computer malfunction to the presence of a virus but one should not be too quick to deduce that. Although viruses have become the biggest menaces of computers, you should remember that the computer is a very complicated machine and any of its components could be the one causing the problem. Do not always assume that when your computer is suddenly not turning on, that it is has been infected with a virus; it could easily be because of a problem in the motherboard, power supply, hard drive and you might need to contact a computer repairÊservice to address this situation.



Not all your computer problems will be caused by a virus; so to effectively address the problem you should first be sure of what you are dealing with. Here are some guidelines that you can follow, to immediately identify the existence of a virus:



Is your computer running slow right now? Do you find yourself waiting too long for a certain page to load or is your computer taking ages to open a folder? If any of these are familiar with you, it would be safe to assume that you are dealing with a virus. However, you can also be dealing with a defective hard drive or RAM. You can check for this easily by hitting Ctrl-Alt-Delete and seeing the performance tab (are they at 100%).



After which, you can check the process tab and see if the CPU is going through large cycles. If yes, then you could very well be dealing with a virus.



Are some of the elements in your operating system missing; like your task bar perhaps? Or are there components in your computer that you cannot control? Is there something that seems to be preventing you to enjoy the normal function of your computer? Some viruses attack your system this way. They tell the operating system to behave this way; and if this happens to your system, a good computer repair service can remedy the situation.



c. Are you often inundated by a barrage of pop-up advertisements while using the computer? If you are having problems with this, you are most likely dealing with a virus and you should contact a repair service. You could simply be loading something and all the pop-ups will begin to appear uncontrollably. Quickly address the situation by finding out if you are truly dealing with a virus and get rid of the problem before it even gets worst.



The truth is, a virus can attack your system in many different ways and you may not even know that you are already dealing with one. The best solution for you is to install an anti-virus software who will keep a guard of your system. When you notice something out of the ordinary, you are most likely dealing with a virus. Be wary of things such as these because they will be indicative of problems within your system. Be observant and do not be complacent; a computer that is healthy is not supposed to give you problems so when your system starts to give you a headache, contact a specialist.

There are many types of computer memory. If you want to upgrade your computer memory, you have to know the different types of memory. Computer memory is an internal storage area that stores data permanently or temporarily. It also affects the speed by which the computer processes the data. Today’s computer has a combination of memory, and not just one type.

Computer memory has four basic types. These are Cache, RAM, Virtual and Hard Drive.

The Hard Drive memory is where you permanently store your data. It contains program files, permanent files, Internet files and files that are saved by the user. The capacity of the Hard Drive memory is measured by gigabytes. The Hard Drive memory capacity of old computers or laptops starts from 20 gigabytes. Today, most computers come with 360 gigabytes or higher.

The Virtual memory plays its role when running applications that are too large to handle by Random Access Memory or RAM. To temporarily store data, the computer’s Operating System uses the Hard Drive and gives it back when needed. Virtual memory’s usage of Hard Drive slows down the performance of the computer.

Cache memory stores the most frequently used processes of the computer. It has 3 grades to indicate its level. Level 1 and 2 are the most common Cache used in most computers and laptop. Level 3 Cache indicates advanced level of systems.

Level 1 Cache memory is used for most frequently used information and processes. It is the primary memory used by the processor. L2 is next in line. It is more commonly used on the motherboard. Depending on the motherboard used in the computer, the L2 can be upgraded or not. L3 is the most advanced Cache memory as it can speed up the memory.

The RAM or Random Access Memory is the most commonly used memory as every file or application that is processed in your memory needs it. Each time a data or application is requested on your computer, the processor sends the request to your RAM, which then processes and writes it back to RAM. But the data that come and go in RAM are temporarily stored. As soon as the application or program is closed, the files are deleted from RAM.

RAM has many types. These are the SDRAM, DDR, SIMM, DIMM, SODIMM, and DRAM.

The SDRAM or Synchronous DRAM retains memory and synchronizes with the timing of the computer. It does not need to refresh. It is faster and more expensive than DRAM. SDRAM’s speeds are 66, 100, 133 and 266 MHZ.

DRAM or Dynamic Random Access Memory holds information for a short time and needs to be refreshed every now and then. It is measured by access time and storage capability.

SIMM is Single In-line Memory modules used to store one row of EDO or BEDO or DRAM chips. SODIMM is Small Outline Dual In-line memory module found in notebooks. It is smaller than standard DIMMs. DIMM or Dual In-line memory module contains 2 rows of DRAM, EDO or BEDO chips. DDR or Double Data Rate doubles the speed rate of data transfer.

Before you purchase the computer memory, you have to know the types of computer memory fit for your computer. Memory used in laptops and notebooks are different from memory used in desktop computer.
