Knowing exactly what makes your Dell laptop run slow will help eliminate the performance drop, so you can enjoy the same snappy speeds you're used to. Continue reading this article asEaseUSwill share what causes your Dell laptop to run slow on Windows 10 and Windows 11.

How to Fix a Dell Laptop Running Slow

As promised, here are a few solutions that should fix your Dell laptop that is running slowly:

1. Remove All External Devices and Restart the Computer

Have you plugged in external devices such as monitors, mice, keyboards, and SSDs or HDDs? Disconnect all of them for anything you have connected to your computer and restart your PC.

The reason you need to disconnect is that these devices use your laptop's resources, and there is a possibility that when starting up your laptop, these devices are consuming too many resources, resulting in your Dell laptop slowing down.

2. Check for Malware

If your laptop is infected with malware, it can corrupt most of your laptop's operations. It can cause your laptop to become unresponsive, prevent it from booting up, and slow it down. Using a malware remover, check for malware and remove it.

You could use a third-party malware remover tool or Windows own Windows Defender to check and remove malware.

3. Optimize the Startup of Windows 10

On your computer, some installed programs could be configured to launch automatically when Windows is booted. This could slow down your laptop. Disabling this will help your laptop boot up faster.

Here's how to disable apps that are set to launch when Windows boots up:

Step 1.Right-click on the "Start" button and select "Task Manager."

Step 2.Click on "Startup."

Step 3.Right-click on the apps that are marked "High" under "Startup impact" and select "Disable."

4. Increase C Drive Space

If your C drive is full, this may be why your Dell laptop has slowed down. Deleting apps and unnecessary files should free up space. Remove unused apps and delete their cache files immediately. Restart your PC and see if your laptop is faster now.

Alternatively, you can also useEaseUS Partition Master, which is trusted by more than 530 million users, to use the extended partition feature and increase Local Disk C's storage space. This should give you more storage space for Local Disk C, and your laptop should run faster now.

Option 1. Extend System C drive with unallocated space

1. 1. Right-click on the System C: drive and select "Resize/Move".
2. 2. Drag the system partition end into the unallocated space so to add it to the C: drive. And click "OK".
3. 3. Click "Execute Task" and "Apply" to execute the operations and extend the C drive.

Option 2. Extend System C drive without unallocated space

1. 1. Right-click a big partition with enough free space on the system disk, select "Allocate Space".
2. 2. Select the system drive at the Allocate Space From (*) To section, and drag the end of System C drive into the unallocated space. Click "OK" to confirm.
3. 3. Click "Execute Task", it will list the pending operations, and click "Apply" to save the changes and extend the C drive.

5. Clean Up the Hard Disk

The hard disk should be cleared if the above solution doesn't help.

Here's a quick way to delete files and increase Local Disk C's storage space:

Step 1.Click on the magnifying glass icon.

Step 2.Search and open "Disk Cleanup."

Step 3.Select the file types that take too much space and click "OK."

Step 4.You'll see a prompt. Click "Delete Files" to delete all the selected file types.

There's even a better solution than the one mentioned above. You can use EaseUS Partition Master's wipe hard drive feature to clear everything in a few clicks and free up space on your hard drive in a few seconds.

6. Defragment the Hard Drive

A corrupted or fragmented hard drive could also cause this problem. As a result, you must defrag the hard drive. Here's how to go about it:

Here's what you need to do:

Step 1.Click on the magnifying glass icon and search "Defragment and Optimize Drives."

Step 2.Select the drive you want to clear and click on "Analyze."

Step 3.After scanning the drive, select it and click "Optimize."

Step 4.Restart your computer and check if your laptop is still slow.

7. Upgrade Dell Hard Drive to SSD

If nothing has worked so far, swap your hard drive with an SSD, as SSDs are much faster and more durable than HDDs. But moving data is a task, and we know that. However, using EaseUS Partition Master, you can clone the data on your HDD and move the exact data to your latest SSD. And SSD storage capacity should be equal to or even bigger than used disk space on Dell HDD.

Then, download EaseUS Partition Master and follow the steps to clone data:

Step 1.Select the source disk.

• Click the "Clone" from the left menu. Select the "Clone OS Disk" or "Clone Data Disk" and click "Next".
• Choose the source disk and click "Next".

Step 2.Select the target disk.

• Choose the wanted HDD/SSD as your destination and click "Next" to continue.
• Read Warning message and confirm "Yes" button.

Step 3.View the disk layout and edit the target disk partition size.

Then click "Continue" when the program warns it will wipe out all data on the target disk. (If you have valuable data on the target disk, back up it in advance.)

You can select "Autofit the disk", "Clone as the source" or "Edit disk layout" to customize your disk layout. (Select the last one if you want to leave more space for C drive.)

Step 4.Click "Start" to start the disk cloning process.

After swapping your HDD with an SSD, check if your laptop runs faster after upgrading the drive. If it didn't, the issue could be with the RAM.

Step 1.Check the specific condition of your RAM: open Task Manager>Performance>Memory.

If the RAM is out of space, you can clean it or upgrade it to a larger one:

Step 2.Turn off the laptop and remove the laptop battery.

Step 3.Check for compatible RAM and install the RAM into the slot.
