What is Slowing Down My Computer?

If your PC is running slow lately, there can be a few common issues including:

  • Some programs run in the background
  • An older OS
  • Not enough RAM and disk drive storage
  • Software bugs
  • Poor internet connection
  • Malware and viruses
  • Numerous start-up programs

It’s normal for an older PC to slow down. So, make sure you update your system for increased efficiency. However, your old PC won’t be able to handle new programs and updates meant for new models.

Oftentimes, we face such issues with our new PC as well. Fortunately, we can root out the cause of slowing your PC and improve its overall performance. Read on to find out.

How to Fix a Slow Computer?

Here are some tips to improve your PC performance.

1. Restart Your Computer

The first thing you should do when your computer is slowing down is to restart it. That would clear the RAM cache and ensure that your system runs the best. RAM provides temporary storage for software and programs as they run. So, it’s obvious that the temporary files can pile up over time hampering your device’s speed.

Alternatively, you can also close all the running programs. But restarting your system would be the best option. Also, many updates aren’t completed until you restart the computer.

The memory leak is another major concern. It disrupts the performance of your system by reducing the amount of available memory. Memory leaks occur when a program incorrectly allocates memory that isn’t required. So, you can restart your computer as it will free up space and clear temporary files stored in RAM.
