How to improve and optimize pc speed? Step by step guide|

Almost every PC user has encountered a situation where their computer slows down significantly without any obvious reason. This often happens when too many programs are open or your PC hasn’t been restarted for a while. Over time, as you install and uninstall programs, bits of software are left behind and can start to conflict with each other or the operating system. This can lead to your computer slowing down or even crashing.
If your computer is starting to slow down, you can do a few simple things to boost your pc speed again.

Restart Your Computer:

This may seem like an obvious first step, but it’s often overlooked. If your computer has been on for a while, restarting it can clear up memory and CPU usage that might be bogging it down. This is especially true if you’ve been using a lot of programs or if you’ve been browsing the web with a lot of tabs open then, Just closing everything down and restarting can make a big difference.

If your computer is crashing or takes a long time to start up, you might have a problem with disk errors. A disk check can help fix these errors and speed up your computer. To do this on Windows 10, type “command prompt” into the search bar, then click on the “Command Prompt” result. Type “chkdsk C: /f” in the command prompt window and hit Enter. This will scan your C drive for errors and fix them.

Adjust Your Power Settings:

If you’re on a laptop, you can extend your battery life by adjusting your power settings. On Windows 10, you can do this by going to Start > Settings > System > Power & Sleep. Under “Related Settings,” click “Additional power settings.”

This will open the Power Options window. From here, you can click on “Show additional plans” and then choose “Balanced (recommended).”

If you’re not concerned about battery life and want your computer to run at full speed, you can select the “High performance” power plan.

Uninstall Unused Programs:

If you’ve been using your computer for a while, there’s a good chance you have a lot of programs installed that you don’t use anymore. These programs can take up space on your hard drive and cause your computer to slow down.

To get rid of them, go to Start > Settings > Apps. Under “Apps & features,” you’ll see a list of all the programs installed on your computer. You can sort them by size to see which ones take up the most space. To uninstall a program, click on it and then click “Uninstall.”

Disable Startup Programs:

When you start your computer, there might be a lot of programs that start up automatically. These programs can run in the background and slow down your computer. Go to Start > Task Manager to stop them from automatically starting up automatically.

Click on the “Startup” tab. Here, you’ll see a list of all the programs that start when you turn on your computer. To disable a program, click on it and then click “Disable.”

Use a Lighter Web Browser:

If you’re a heavy web user, the web browser you use can significantly impact your computer’s speed. Some browsers, like Google Chrome, are very resource-intensive, which can slow down your computer. If you’re using Chrome and your computer is slow, try switching to a lighter browser like Mozilla Firefox or Microsoft Edge.

Delete Temporary Files:

When you use programs on your computer, they often create temporary files. These files can take up space on your hard drive and eventually slow down your computer. You can delete them by going to Start > Settings > System > Storage.

Under “Local Storage,” click on “Temporary files.” From here, you can choose which types of files you want to delete. Be sure to select “Temporary files” and not “Recycle Bin.”

Defragment Your Hard Drive:

Over time, the files on your hard drive can spread out, making your computer run slower. To fix this, you can defragment your hard drive. This process will group all the files and make them easier for your computer to access.

To defragment your hard drive on Windows 10, type “defragment” into the search bar, then click on the “Defragment and optimize your drives” result.
In the window that opens, click on the drive you want to defragment and click “Optimize.”

Check For Viruses And Malware:

If your computer is slow and you’re unsure why it could be due to a virus or malware infection. These malicious programs can take up a lot of resources and cause your computer to slow down.

You can use the Windows Defender program to scan for viruses and malware. To launch it, type “Windows Defender” into the search bar and click on the “Windows Defender Security Center” result.

Click on the “Virus & threat protection” icon in the Windows Defender Security Center window.
Under “Threat history,” click on “Scan now.”

This will start a full system scan, which can take a while. Once the scan is complete, Windows Defender will remove any viruses or malware it finds.

Upgrade Your Hardware:

If you’ve tried all the above tips and your computer is still slow, you might need to upgrade your hardware. This is especially true if you have an older computer.
If your computer has a slow processor or not much RAM, upgrading to a faster processor or more RAM can make a big difference. If you have an older hard drive, consider upgrading to a solid-state drive, which is faster and more reliable.

Upgrading your hardware can be a significant investment, so it’s essential to make sure that it’s the hardware causing the problem before you go out and buy new parts.
