Why Does My Computer Keep Freezing? [10 Easy Fixes]

The computer freezing randomly is not uncommon but can be alarming if it persists or gets longer than usual, signifying a chronic freeze.

Your computer keeps freezing due to overheating, driver corruption, low memory storage, too many programs running in the background, malware, or faulty external hardware.

Many of these problems come with an easy fix, but you should know when to give up on repairing your PC.

Read on to learn about the problems that nag your computer and how to fix them quickly.

Why Does My Computer Keep Freezing?

A freezing computer is not an uncommon issue, where every user at one point in time will experience it.

However, it could be alarming if your computer randomly freezes or displays a frozen screen for 5 minutes daily.

Remember, you must be experiencing a chronic freeze issue caused by malfunctioning software and hardware, a virus, or simply an outdated system.

Therefore, there are one or multiple reasons why your computer would freeze.

1. CPU Overheating

CPU overheating is one of the most common reasons behind freezing computers.

Remember, any technical device would stop working to prevent further damage when it overheats.

Once the processor gets too hot, the built-in protection will shut down the system before the rising temperature can harm other components.

Therefore your computer is likely to freeze, display an error screen, or shut down when the CPU overheats.

There are multiple reasons for an overheating CPU.

  1. A faulty or dirty cooling fan will prevent warm air from escaping the device, leading to an overheated CPU.
  2. The dust accumulating inside the cooling fan will prevent the internal air from escaping.
  3. Overclocking the RAM will intensify the computing computer along with the internal temperature.
  4. Worn-out thermal paste will fail to transfer heat from the motherboard to the cooling vent.
  5. Running the heavy application on a PC with low ram storage will usurp high computational power, leading to an overheated device.
  6. Exposing the device to direct sunlight will also raise the internal temperature leading to an overheated CPU.

2. Outdated or Corrupt Driver(s)

Did you know driver issues directly or indirectly cause 75% of PC crashes?

A computer using outdated or corrupt drivers is more likely to experience random freezing whenever you attempt to run an associated application.

For example, trying to run a 2K video game using an outdated graphics card will cause the screen to freeze.

Similarly, attempting to run a video game will immediately shut down the application if the associated driver is corrupted.

An example of a frozen gaming screen is shown in the figure.

It indicates that the existing graphics driver has less than the computational power to run the game smoothly.

Therefore, the driver-related issue is more common and often invites chronic computer freeze when accessing particular applications.

How to Diagnose Driver Issues on Windows?

  1. Click Win + R, type “devmgmt.msc,” and press Enter.
  2. type devmgmt-msc on dialog box

  3. Expand each driver to check whether it displays a yellow exclamation mark.
  4. yellow mark in drivers

  5. It means that the driver is outdated and requires an immediate update.

However, figuring out a corrupt driver may not be that simple.

Remember, whether you recently applied a driver issue fix or installed older updates that may have altered the existing driver’s state.

3. BIOS Freeze

Sometimes, your computer may freeze at the BIOS stage due to altered settings preventing a successful start-up.

BIOS is a firmware designed to handle the operating software, and any change in the core system setting will directly affect the BIOS.

Here are some probable causes that may have adversely affected the BIOS.

  1. You have altered the CMOS and overclocked the RAM.
  2. An unauthorized program installed made changes to the BIOS setting.
  3. Using the USB device without installing the right driver.
  4. Corrupted software that affected the sound card or other components.
  5. Faulty or malfunctioning HDD (Hard Disk Drive).

Although rare, using an unlicensed version of Windows could also alter the BIOS, leading to a freeze.

4. Low or Damaged Memory Storage (RAM)

Trying to run a heavy application on a PC with low memory storage is the typical cause of a freezing PC.

Sometimes, hidden system files and cache clog up RAM, limiting the memory available for other programs.

It will cause RAM over-burn as it attempts to run multiple applications with limited memory storage, causing the system to freeze.

5. Faulty Hardware(s)

Encountering faulty or incompatible hardware will likely cause the computer to freeze.

Here is a list of common hardware problems that will cause chronic computer freeze.

  1. A defective HDD prevents the computer from accessing the operating software.
  2. Incompatible RAM sticks will fail to provide necessary memory storage
  3. A faulty video card will invite an incompatibility issue.
  4. The damaged cooling vent and fan will overheat the CPU
  5. A faulty motherboard will prevent access to the main components
  6. The power board issue will cause a momentary loss of electricity required to power each component.

Plugging faulty external devices like a mouse and keyboard may cause the computer to freeze.

The problem manifests when the USB disk or the USB port driver is corrupted, including a USB malfunction, faulty USB disk ejection, and a defective port driver.

6. Faulty Software(s)

Similar to a faulty hardware problem, a mishap or corrupt software may also cause random computer freeze.

However, unlike the hardware issue, the computer freeze will only occur when you run the particular application.

It mainly occurs when you install corrupt (incompatible) software, software with missing files, or incomplete software.

The application will fail to start correctly or operate against the system’s preference, which causes a temporary computer freeze.

The corrupt software sometimes takes up a significant amount of RAM and high-computational power, which undermines the system’s ability.

You can diagnose it by checking for CPU and RAM usage.

  1. Press Cltr+Alt+Del and click Task Manager.
  2. select task manager

  3. Under Processes, check whether the suspicious application is using 100% of CPU, memory, and disk space.
  4. under processes check application using RAM usage

7. Mac Freeze

Like RAM on PC and laptops, Mac’s RAM may also encounter memory issues leading to Mac freeze.

Known as PRAM/NVRAM, the error with the memory storage can cause the device to freeze. Sometimes the NVRAM will become corrupt, needing to clear it by performing a PRAM reset.

Unlike Windows, Mac does not necessarily encounter computer freeze because of proprietary hardware and software usage.
