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 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, 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. See the operations below.

Try It FREE. (Windows 10/8/7Vista/XP is supported)

Step 1. Install AOMEI Partition Assistant to your Dell laptop/PC and launch it. Right-click the D: drive (you can also choose another hard dive which has free disk space), and select Allocate Free Space.

Allocate Free Space

Step 2. Select C: drive to allocate free space from D: drive to C: drive. Click OK.

Allocate Free Space from D to C

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.

Apply Proceed

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.

3. Select Settings-> Advanced-> Change...

4. Here, select the hard disk whose virtual memory you wish to manage, and then, click “Custom Size”. input a desired amount of memory, which is taken from your disk’s current space availability.

5. Click OK to save all settings and changes.

Restart your laptop or PC to see whether it is running faster than before.

Method 6. Run a virus scan and reset system to factory defaults

If those methods won’t solve your problem, we finally recommend you to run a virus scan on the system, and then, backup the data and reset the system to factory defaults with the recovery partition installed by Dell. If you have backed up system before, you can also restore computer to earlier state with the system image.
