The following article provides information on why Dell PCs may slow down over time and how you can fix this on your PC.
This article covers reasons why your system might have slowed down and things you can do to resolve this.
If you are having system hangs, freezes, slowdowns or other performance issues please go through the guide below first before returning to this page.
Every computer will work harder for the same results as the years pass. Commonly this happens a few years after the purchase of PC, but there are cases when the system 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.
The most common reason for you to notice a deterioration in performance, is that when you first get a PC it has had a clean image/Operating System (OS) installed along with your programs from the factory and that image has been tested as working fine. Over time that image is changed by whoever uses the PC. The more often it is changed, usually the quicker you will start to see issues.
All users will download and install new programs, applications, updates and drivers over time. They will also uninstall programs and applications they feel they 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 will often leave parts of themselves behind. The OS has to navigate these changes and dead ends in order 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 and more information, programs and data on your system. The larger the hard drive (HDD) is and the larger the amount of data you have on it, will also adversely affect its performance. Files on your HDD are saved as small parts of the whole file and they are usually saved wherever there is space available on your HDD. This means every time 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 will be. This is why all PC manufacturers recommend you follow basic system 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 HDD's over time is that the more data your HDD holds the less space is available for what the system calls your Paging File. This is space that your system 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, by being 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 make sure your HDD is never completely full and that you backup unneeded data off of your HDD whenever possible.
Another possible fix is to add a Solid State (SSD) hard drive into your PC as your Boot drive. The Hard drive that your operating system boots and runs from. They have significantly 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. There are programs that check for any processes or programs that are taking up your systems resources. There are also special programs that check for dead/orphan files and for 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 system stability and can cause boot issues.
Another software issue is corruption of the data that your HDD holds. If the corruption is bad enough it will affect how your system operates. Corruption can be caused by a host of things but it’s mostly bugs in the operating system from updates, corrupted RAM data, static electricity, power surges and for the normal operating system decomposition with age that all Windows users report.
We also can’t ignore that fact that for most PC users, malware and viruses will all too often contribute to a computer slowing down. Our systems come with antivirus installed, but it's up to you if you to configure and use it or another to get another program to use in its place. It's up to you how often your scan your system and how you behave when you're online.
The good news is that all of these software issues will be resolved by a clean install of your operating system and programs and drivers.

The most common sign of your system having memory issues is for the OS to report multiple memory errors. Such as memory overflow and not enough memory. Not having sufficient RAM in your system 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 and yet the memory is passing all the diagnostics, then you may be looking at having to add memory to the system. As the operating systems develop and as programs become more and more resource hungry, I'm afraid the same amount of RAM as worked fine in Windows XP, would simply not be much use in Windows 7 if it was put under any kind of stress.
