Want to fix up computer freezes


My desktop computer has been in use for about 3 years. Since about 2 weeks ago, my computer started to freeze while browsing, opening folders, opening desktop applications such as Skype or Slack, or anything else. Because of this situation has happened too many times, so I decided to ask for help. I want to understand what is going on, and how do I fix my computer from freezing?  Don’t let me reinstall the system, I think those operations are too troublesome. Any help, I will be very grateful.

- Question from tom’s HARDWARE

Why is my computer freezing up?

Below, I have summarized the six most common reasons of computer freezes randomly for you.

☞ Too many applications running
☞ Operating system problem
☞ Insufficient system drive
☞ CPU overheating
☞ External device malfunction
☞ Computer Viruses

What to do if your computer freezes in Windows 10?

Now we will check these reasons one by one. For each reason, I will demonstrate the specific steps.

Method 1. Clean up background programs

Every application opened on the system requires some internal and hardware resources to keep running. Starting too many programs at the same time may cause the computer to run slowly and freeze. If this is the case, we may need to terminate some program processes to make it work properly, to ensure that the computer will not freeze due to running multiple applications at the same time.

1. On your keyboard, press Ctrl, Shift and Esc at the same time to open Task Manager.

2. Right-click on the programs that are listed with (not responding) and click End task.

Method 2. Make sure operating system is the latest version

The purpose of the Windows 10 update is to stabilize the smooth running of the system and fix bugs, please confirm that the latest Windows 10 is installed. You can open the control panel in "Start", then click "Update and Security", in "Windows Update", select the "Check for Updates" button to install and update Windows 10.

Method 3. Extend system drive

If your system drive is running out of space, computer freezes can also happen from time to time. Please make sure you have enough free space on the system drive.

I recommend AOMEI Partition Assistant Standard to you. It is a completely free third-party disk management utility.

You can use it to resize partition or delete partition. If you have adjacent empty partitions or non-adjacent unallocated space, you can use merge partition to extend the system drive instead of deleting partitions to create adjacent unallocated space via Disk Management.

Step 1. Install and launch AOMEI Partition Assistant. Right click the partition which you want to merge, and select "Merge Partitions".

Step 2. Choose the partition that you need to be merged (if your D drive is empty) and click “OK”.

Step 3. In the main interface, after confirming operation, click “Apply” and “Proceed” to commit it.

But please note, what should you do if you do not have unallocated space or other partitions also have important data and cannot be merged directly?

I recommend you to upgrade to AOMEI Partition Assistant Pro, because the function of allocate free space from one partition to another can help you solve this problem. As long as there is free space on your other partitions, you can extend the system drive.

PS.:You can download for free trial first.

Step 1. Install and launch AOMEI Partition Assistant on the computer. Right click the partition you want to allocate from and select “Allocate Free Space”.

Step 2. In the pop-up window, it gives you option to specify the space size and destination partition. Select C drive from the given list.

Step 3. Here is a virtual outcome. Don’t forget click “Apply”.

Method 4. Clean up the dust

If the temperature of your system processor is higher than usual, the computer may freeze. The fan on the computer CPU is used to dissipate heat, but due to static electricity, it attracts a lot of dust. If it is not cleaned for a long time, the air outlet will be blocked by dust, which may also cause the computer to freezes. You can usually clean up dust to improve the heat dissipation efficiency of your computer. For more information, you can check out:  Clean Intel Heatsink + Fan for Lower Temperatures!

Method 5. To deal with external devices

The wrong USB or external devices connected to the system may also cause Windows 10 to crash randomly. External devices connected to the computer (such as a mouse, keyboard, USB camera, or game console) may be the actual cause of the problem.

Remove all the connected devices to check if the system works normally. Also, update the USB device drives to prevent such issues.

Method 6. Scan for Virus

Viruses are the main cause of computer failures, and virus or malware infections can also make computer freezes randomly or run slowly. A computer virus is actually a self-replicating program or scripting language. These computer programs or scripting languages use defects in the computer's software or hardware to control or damage the computer, causing damage to the computer.

In order to keep your computer healthy, it is recommended you to use a good anti-virus software to scan the system regularly.


From what has been discussed above, I have listed the six most useful methods for solving computer freezes in Windows 10. If the problem still cannot be solved, then it may be a computer hardware problem. It is recommended that you send it to a repair shop for professional repair.​
