Computer Repair Guide: Ways to Speed Up a Slow PC 

Here are the things you can do to fix your slow-running computer. 

Identify and Shut Down The Programs That Slow Down Your PC

Many resource-intensive programs or apps may run in the background of your computer, which may cause it to run slowly. These programs may start automatically, or you may have forgotten to close them. 

Closing these programs or uninstalling the apps you no longer use can significantly help speed up your slow PC. To do this, you first need to identify the resource-intensive programs. To do this:

  • Press Ctrl, Alt, and Dlt on your keyboard and open the Task Manager. 

On the processes tab of your Task Manager, you will see the apps running in the background and how much space they are taking. You can close them from there, or if these are the apps you no longer need, you may even uninstall them from your PC.

Free up Storage Space

Another computer repair tip is to free up storage space. You can do this by deleting programs and files you no longer need. Not only this, but every time you surf the internet, its history remains on the computer.

Clean Your PC

  • Use a household vacuum to suck dust from the internals of the computer. 

However, you must be very careful about this, as doing it incorrectly may cause damage to the internal parts of the computer.
