This article covers reasons why your computer might have slowed down and things you can do to resolve this.
If you are having computer stops responding, is unavailable, slowdowns, or other performance issues please go through the guide below first before returning to this page.
Every computer works harder for the same results as the years pass. Commonly this happens a few years after the purchase of personal computer. However, there are cases when the computer slows after its only been used for a few months.
There are several causes. Each person who uses a computer will use it for different tasks, so it usually comes down to how the machine is being used over time.
What is the most common reason for you to notice a deterioration in performance? When you first get a personal computer, it has a fresh image/Operating System (operating system) installed along with your programs. It comes from the factory like that and the image has been tested. Over time as you use the personal computer, that image is altered. The more often it is changed, the quicker you start to see issues.
All users will download and install new programs, applications, updates, and drivers over time. They uninstall programs and applications they feel you no longer require. The new files alter and change the old files, sometimes for the worse. The uninstalls never remove themselves fully, 100% of the time and leaves parts of themselves behind. The operating system has to navigate these changes and dead ends to complete the jobs you set it.
Some of these changes are optional and some are mandatory for the operating system. The point is, over time the software and files will change and this will more often than not have a detrimental effect on performance.
Over time you will gather more information, programs, and data on your computer. The larger the hard drive (HDD) is and the larger the amount of data you have on it, affects its performance. Files on your HDD are saved as small parts of the whole file and they are saved wherever there is space available on your HDD. This means every time that it searches for files, it has to search the whole of your drive and recombine them. Obviously the more it has to search through and the more parts there are to locate, the slower it is. This is why all personal computer manufacturers recommend you follow basic computer maintenance like running Defrag on your HDD. It reorders the files on your drive to locate as many parts of a file as possible, and move them as close together as possible.
If you want to look into this further, look up the terms Defragment and Contiguous.
Another issue with HDDs over time is that the more data your HDD holds the less space is available. This free space is used for what the computer calls your Paging File. This is space that your computer takes from the HDD to create virtual memory space to help your system memory (RAM) operate. It allows the RAM to switch between programs more quickly. It is able to cache and pickup memory from the RAM onto the drive and then back to the RAM when needed. The way to avoid this is to ensure that your HDD is never full and that you backup unneeded data off your HDD whenever possible.
Another possible fix is to add a Solid State (SSD) hard drive into your personal computer as your Boot drive. The Hard drive that your operating system boots and runs from. They have quicker read times and are not intended for the storage of large amounts of data.
There are special programs that identify applications that take up space on your computers hard drive. Some programs check for any processes or programs that are taking up your computer's resources. There are also special programs that check for dead or orphan files and unneeded entries in your Registry. These programs can be useful. Unfortunately, they are also well known for being spyware and for causing issues themselves, if you let them delete files without understanding what those files do. This can seriously affect your computer stability and can cause boot issues.
Another software issue is the corruption of the data that your HDD holds. If the corruption is bad enough, it affects how your computer operates. Corruption is caused by a host of things. However, it is mostly bugs in the operating system from updates, which are corrupted RAM data, static electricity, power surges. Or it is part of the normal operating system decomposition with age that all Windows users report.
We cannot ignore that fact that for most personal computer users, malware, and viruses contribute to a computer slowing down. Our computers come with an anti-virus installed, but it is up to you if you to configure and use it. Alternatively, get another program to use in its place. It is up to you how often you scan your computer and how you behave when you are online.
The good news is that all these software issues are resolved by a clean install of your operating system and programs and drivers.

The most common sign of your computer having memory issues is for the operating system to report multiple memory errors. Such as memory overflow and not enough memory. Not having sufficient RAM in your computer causes your HDD to try to compensate for it. The computer will constantly seek more RAM, taking away resources from other tasks. If you are constantly getting memory errors, but the memory is passing all the diagnostics. You may be looking at having to add memory to the computer. Operating computers update and go through development. Programs become more resource hungry. The same amount of RAM that worked fine in Windows XP, is not much use in Windows 10 when it is put under any kind of stress.
