Does your PC spend a lot of time loading software applications like Excel, Word or any commonly used application? This strange behavior is equally true for newly purchased as well as old PCs. Here are the Top 10 most probable reasons why your PC is slow.

1. Spyware is a name given to a software program that has malicious intentions and downloads itself without the user’s consent or knowledge. They can do all sorts of nasty things and slow down the computer considerably.
2. Installation of many programs under the StartUp menu. As you install applications on your system, some of them take up start-up status discreetly. This results in slower start up times as all of them take up memory for initialization. As a result, booting up a system consumes a lot of time.
3. Corruption of the Windows registry. The Windows Registry is regarded as the master control center of the operating system and all the applications that it executes. If it is corrupted, it can lead to a variety of performance problems like slow Windows start ups and shut downs along with general disturbance in Windows processing activities.
4. Fragmented memory. When you use your PC on an every day basis files stored on the computer gets ‘scattered’ and thus consumes noticeable time for file searches.
5. Security software may aim to protect you but their constant surveillance against all kinds of malicious software can actually contribute to slow PC performance because they take up a lot of main memory. By all means install and use security software but ensure that settings are at its best for you (e.g., using the Ignore List, etc.) so that it does not meddle with your everyday PC tasks.
6. Improper removal of programs. When programs are not uninstalled properly, they leave certain things behind. This results in cluttering the Windows registry with invalid and obsolete data, occupying plenty of unwanted space.
7. Page file size. This is known as the temporary work area in the memory used by a system for efficient processing of various functions. Think of it as a buffer used by the operating system. If you allocate only a small portion of memory for this, the consequence may be poor performance and system instability.
8. Permanent Internet files. If your Temporary Internet folder is never emptied, all the used memory will make your PC slow.
9. Viruses are software programs with malicious intentions and cause irreparable damage to computers. It is also the most prevalent reason of reducing the speed of computers as they can sap down computer performance and cause frequent shut downs.
10. Hardware problems. Last but not the least, hardware problems as a result of dust, overheating and wear and tear of components can cause sluggish PC performance.

I hope the above helps you understand just how many factors can cause slow PC performance.
