Method 1. Run diagnostics on the hardware components of the system

If you are in the same situation as the scenario said, you should try to run diagnostics on the hardware components of the system. To run diagnostics, you can do as following steps:

1. Restart the system. When the Dell logo shows up, tap the F12 key every two seconds. It will start the One-time boot menu.

2. In the One-time boot menu, using arrow keys to select Diagnostics and hit Enter. This operation will run diagnostics on the hardware components of the system, and it may take around 5 minutes.

Method 2. Change Microsoft system configuration utility

If there are too many unnecessary programs loading at the very first, it would cause Dell Inspiron slow startup. Thus, you can change the system configuration to speed up your PC.

1. Press Windows key + R key to open the Run dialog.

2. Type msconfig and press Enter.

3. Choose Startup tab and uncheck programs that you feel unnecessarily loading.

4. Click Apply and OK.

It will prompt you to restart, and the changes will take place once you will restart.

Method 3. Optimize your drive to help your computer run more efficiently

Over time, files on your hard drive get fragmented, and your computer slows down because it has to check multiple places on your drive for those pieces. This may be one of the reasons that cause your Dell Inspiron running slow. Thus, if you notice files are taking longer to load, you can see how fragmented the drive is in Windows 11/10/8/7 and decide whether to defrag disk or not. Do as below:

1. Press Windows + R keys simultaneously. In the Run dialog, type dfrgui and pressEnter. Or you can type optimize or defrag in search box to open the disk optimization tool.

2. Select the hard drive and click Analyze to find out if they need to be optimized. (if you have a SSD, this option is grayed out and not available).

3. Check the percentage of fragmented files in the results. If you want to defragment your drive, click Optimize.

*Disk Defragmenter organizes all existing files and settings in the computer, effectively increasing its running speed.

Method 4. Increase system partition for speeding up Dell Inspiron

System drive running out of space will slow down the PC’s running speed. Thus, if your PC running slower and slower, and you received a low disk space warning, extending system partition would be an effective way to speed up your PC. 

Windows users all know that the Disk Management can help extend partition. To extend C: drive with Disk Management, do as following steps:

1. Right-click the C: drive.

2. Select Extend Volume in the menu, and then, extend the C: drive with the contagious unallocated space behind C: drive.

However, if there is no unallocated space adjacent to the C: drive, the Extend Volume would be grayed out. Thus, here we highly recommend you to use a third-party software, the AOMEI Partition Assistant Professional, which can help you increase C: drive no matter the unallocated space is adjacent to the C: drive or not. It can even increase system partition by allocating free space from other partitions. It has many other features, covering moving apps from one drive to another, migrating  OS to SSD, etc.

Step 3. When you back to the main interface, you can see that the C: drive has been enlarged. Click Apply-> Proceed to submit the operation.

AOMEI Partition Assistant also allows you to merge two small partitions into a bigger one. You can even use it to upgrade a small hard drive to a larger one, or you can replace your old HDD with a new SSD without reinstalling OS. They all can help you improve your PC’s performance and speed it up. 

Method 5. Change Virtual Memory

Virtual memory is used to compensate for the lack of RAM on your computer. Applications use virtual memory to save and load temporary information, effectively increasing your system's performance.

1. Press Windows Key + R key, typeControl Panel, and press Enter.

2. Click System and Security-> System->Advanced System Settings.
