Having your computer deadlock while you are using it can be very frustrating, most times you have no choice but to leave it alone and let it come back to normal by itself. Then you have to hope that it is a one-time occurrence. But you don’t have to keep using your computer like that, this article will open your eyes to why your computer is deadlocked and simple fixes for a deadlocked computer.


Is my computer deadlocked? 

It is not every time that your computer screen freezes up that it is deadlocked, if your laptop is deadlocked, it won’t be able to perform even the simplest tasks such as moving the cursor or lighting up the Caps Lock button when it is on. Deadlock in a computer is usually a result of having two or more programs trying and unable to use the same resource at the same time. Before moving on to reasons for the deadlock and how it can be fixed, you have to first determine if your laptop is deadlocked or if it is just a tiny computer glitch.


The following steps will help confirm if you are dealing with a deadlock PC:

  1. Turn on the Caps Lock button on the keyboard. Whenever you press the Caps Lock button a tiny white light will come on to show that it is on, if this happens then your PC is not deadlocked, and you will need to run a deeper diagnosis. However, if the light does not come on, even after some minutes, it shows that your computer is deadlocked.
  2. Move your mouse cursor around. As said earlier, a deadlocked computer will be unable to perform the simplest tasks, so if you suspect that your laptop is deadlocked, try moving the mouse cursor around. If the cursor moves along with the mouse or a few minutes after, then your PC is not in deadlock mode. If the cursor does not move, even after a few minutes, then you can be sure that the system is in deadlock.


Why is my computer deadlocked?

There are several reasons why your computer will go into a deadlock, and knowing which of these is responsible for your present predicament will give you an inkling of how to solve the problem. Different strokes for different folks right?

Your laptop will deadlock if:

  • It is overheating due to blocked air vents
  • It has insufficient RAM space
  • It has outdated drivers
  • It has too many programs running in the background
  • It has been invaded by a virus or malware
  • It has corrupt system files
  • BIOS is incompatible with the system due to modifications or upgrades
  • There’s an external hardware problem
  • There are software issues.



Proper ventilation is required to keep your PC in perfect working order. Heat is generated when you use your computer, this is why there are fans underneath the board to keep it cool while you are working. If these fans are unable to perform their functions due to blocked air vents or any other issue, the computer will overheat and deadlock.

You can prevent overheating by frequently clearing your air vents, placing your PC on a hard and flat surface, working in a well-ventilated room, and so on.

Insufficient RAM space

Having insufficient space on any device is a problem. A laptop requires a lot of storage space to perform even basic processing functions. If you do not have a lot of space on your computer, you will be unable to do anything on it until sufficient space is cleared.

You can free up RAM space by deleting all temporary files on your laptop, to delete temporary files, input the word “temp” in your system search box and click on OK. Highlight the results and delete them.


Outdated drivers

If your computer drivers are incompatible with the current system upgrade or windows, then it will lead to miscommunication between both parties. The drivers might also be unable to properly perform some tasks, this will lead to frequent freeze-ups until the device drivers have been upgraded.

Use your computer’s “Device Manager” to upgrade hard drives and prevent constant freeze-ups.


Too many programs running in the background

If you have too many applications or programs open on your computer, it will sometimes lead to conflict as the programs might not work properly due to the inability to gain sufficient access to some resources. When this happens, you will have a deadlock until some of the programs have been closed down.

You can exit programs by opening your computer’s “Task Manager” and ending unresponsive tasks.


Virus or Malware

The presence of viruses or malware on your laptop can also disrupt the smooth running of certain computer programs. When you open these programs, the interaction with the virus might make the computer freeze up. The deadlock will continue until the virus has been terminated.

Antivirus software will help you detect and terminate the virus.


Corrupt or Missing system files

Deleting files on your system because they are weirdly named is something a lot of people do. Some of these files might contain information that is essential to your system, if the computer is unable to detect these files, it would freeze up and be unable to accomplish the task it has set out to do.

You can recover deleted system files by using Microsoft’s System File Checker (SFC) tool. This tool will repair and replace corrupt and missing system files.


BIOS issues

When you introduce a new program to your computer or some modifications to your BIOS, you never can tell how it will affect the operation of your computer until it is too late. Adding a corrupt or incompatible modification to your BIOS will cause a deadlock in your computer. You can solve this issue by running a “System Restore”.

System restore will return your computer to an earlier date and time when your system was working perfectly. But you must create a restore point before running system restore.



A deadlock computer is not a serious issue, most of the time you can return it to proper working condition yourself. If the above solutions do not work, taking your laptop to a repair specialist is the advisable course of action.
