Why is My Computer So Slow? How to Fix a Slow Computer


It can be frustrating when you’re trying to do something and your computer is slowing you down or not responding quickly. A slow computer can be caused by a variety of problems, and if it is consistently getting slower over time it might also be time to ask for professional help.

Reasons Why your Computer Might be Running Slower than Usual

1. Too Many Active Programs

When you have too many active programs open, your computer becomes cluttered. This slows down the speed of your computer and causes the programs to run slower. It’s best to close any programs, as well as web browser windows/ tabs you aren’t using.

2. Old Computer Hardware

If you’ve had your computer for quite some time, chances are it has become outdated by newer models that are faster and more efficient. If your PC is outdated, its likely slow because the hardware is outdated. It’s time to consider getting a new one.

3. Hard Drive/Memory Maxed Out

If your computer is maxed out on memory or hard drive space, it can slow down and even get to the point where it won’t work at all. To fix this, you will need to use a program such as CCleaner, or you can purchase a new hard drive or memory.

4. Corrupted Programs

Some programs that you install may not be compatible with the rest of your computer, which slows down its performance. Programs that are not designed for your computers architecture, or that are designed for another operating system can take up valuable space on your computer. You need to go into your disk and uninstall any program that might be causing your computer to slow down.

5. Virus or Malware Infecting Your Computer

If you’ve recently downloaded any sort of software or file from an untrusted source online, there is always a chance it could have infected your computer with malware. If this is the case, it is best to contact a professional to assist you in the removal of the malware. It is many times the case that simply downloading antivirus software after already becoming infected will not actually remove malware from your device.

6. Unnecessary Software Updates

Some programs may be downloading unnecessary updates automatically during the day, or even at night which can slow down your computer. You will need to update these programs on a schedule that is conducive for your computer use schedule, or if it is a software that you never use, either uninstall it or disable auto updates for that specific software program.

7. Many Apps Opening Automatically When PC Starts

Each time you start your computer, there are multiple apps that you have turned on that will automatically open and slow down your computer. To fix this, go to “run” and type in “msconfig”. Click the tab for startup. You will see all the programs that automatically start when you turn on your PC. Uncheck any programs that don’t need to be running each time you reboot your PC. Alternatively use CTRL+ALT to open the task manager and close all unnecessary apps.

8. Computer Running In Low Power Mode

If your computer is running in low power mode, it will run slowly. You should turn off low power mode by changing the settings on your computer and selecting “High Performance” or anything synonymous to that setting in the battery and performance settings.

Bottom line

It is important to rule out these problems before just deciding to get a new device.
