Top 10 reasons that may slow down your computer

Here are the top reasons why your computer is slowing down. So, let’s get started.

1. Disk fragmentation:

When we install any program, it loads on your hard disk in blocks to utilize maximum space. These files are divided into fragments whenever they are moved to different areas of the hard disk, so that it can provide easy access whenever the user wants to open. This file fragmentation occurs when hard disk is low on memory. So if you have a very little free space in your hard disk then it may slow down the computer speed dramatically.

2. Outdated drivers:

Drivers are generally the set of instructions that helps to communicate between hardware and software components. If there is no proper communication between them then there is a chance that it may lead to slow computing.

3. Overloaded or corrupt registry:

Whenever we use any program, it writes some bits of information in registry file and read from here as well. Sometimes due to multiple applications running simultaneously, registry gets corrupted and leads to bad performance of the system.

4. Excessive startup entries:

Whenever any program is installed, it adds some of its components in the boot section so that it may run automatically whenever you start your system. This enhances the time as well as reduces performance of your computer as there are many programs running simultaneously. So it’s said to be good practice to maintain the number of startup entries to bare minimum.

5. Slow speed cpu fan:

When we use computer for a long time, the processor generates lots of heat and fan is required to cool it down. If your fan speed is not sufficient or if it has some issues then there are chances that you may face “computer running slow” problem.

You can change your cpu fan speed using bios configuration, however, if you are thinking how to change cpu fan speed without bios then you can search it on google.

6. Incorrect User Settings:

Each user has its own profile in Windows which stores all the necessary data related to that user. So it’s your duty to maintain the size of hard disk partition and other settings such as memory, screen resolution etc. increased by default.

7. Virus Attacks:

Virus may also affect your computer performance badly and even lead to system shutdown if you are not maintaining a good antivirus installed in your computer. Also, it’s a good practice to go for advanced virus protection if you are facing this kind of issues continuously on your system.

8. Incomplete installations:

Sometimes due to incomplete installation of some applications, they may create problems while running on the background and ultimately affect the performance of entire system. So it’s better to update all the software installed in your computer.

9. Programs running on background:

If you are working on some important task and suddenly system get hanged due to any application running in t system resources. So you should immediately end this process to get back system into normal state.

10. Hardware Issues:

If you think that all these factors may affect your computer and system is still running slow then it may be a sign of hardware issues like bad hard disk, low RAM etc. In this case, we recommend you to get your system checked by professional engineers instead of tinkering with it on your own.
