Is your computer slowing down? Do you find it easier to move a mountain than multitasking on your machine? Here are 6 possible reasons that might explain the poor performance of your computer.

#1. Poor RAM
RAM (random access memory) is a crucial part of a computer. If your computer does not have enough of it, then it starts slowing down. As apps and programs are becoming more technologically advanced, your computer requires more RAM juice than ever. In absence of enough RAM, the hard drive tries to fill in for the memory gap, and that is what keeps your system from performing well.

What to do?
Increase the RAM and see if it helps.

#2. Unnecessary software
Oh look, a free video downloading software. There’s no way I am leaving it out!
Our obsession with free software on the Internet is one of the biggest factors that bloat our computers and cause them to perform poorly.

What to do?
Simple. Get rid of software which you rarely use.

#3. Too many startup applications
There are several applications that automatically start when you start your computer. These are called startup applications and they eat up system resources like crazy. While most of these applications may be necessary, they must be used only when needed. It’s like, the moment you reach for your toothpaste and brush, the tap starts running.

What to do?
Press Win + R. Type msconfig. Uncheck programs that do not need to run during startup.

#4. Lack of Defragmentation
A slow computer, in most cases, is a fragmented computer. Fragmentation takes place every time a file is saved, modified or deleted. Now, all such changes are saved in small bits across the hard drive. Now, these bits are not necessarily placed contiguously and in a logical order. So, when you want to access a modified file, the computer runs a search in random locations and this affects its performance.

What to do?

  • Go to Start→Control Panel→System and Security. The Administrative Tools window appears.
  • Click Defragment Your Hard Drive. The Disk Defragmenter dialog box appears.
  • Click the Analyze Disk button. …
  • When the analysis is complete, click the Defragment Disk button. …
  • Click Close

#5. Cryptojacking

A cryptocurrency is a form of virtual or digital money that uses cryptography for security. To generate (mine) this currency, a computer’s processing power is required. Cryptojacking (or cryptocurrency hijacking or cryptocurrency mining malware) is the secret use of your computer’s CPU power to generate cryptocurrency without your consent or knowledge.

If your computer is being used for cryptojacking, it will start showing signs of poor performance and lag in execution. Your Internet connection might slow down and your CPU fan might run faster than normal or make an unusual whirring sound.

What to do?
Install an antivirus software that can block access to websites compromised with crypto mining scripts.

#6. Malware
Malware is all that defines viruses, Trojans, worms, spyware, adware, rootkits, etc. Not only these malicious programs pose a huge risk to your personal data but they affect device performance computer’s as well. They perform unwanted operations in the infected computer, making it incredibly slow and at times, non-functional altogether.

What to do?
Again, install an antivirus software built with multilayered defense. It should be able to block all sorts of malware, infected and malicious websites.
