Windows 10 freezes randomly Solved

Since October 2017, Windows 10 has been freezing a lot more that usual. (That’s when Microsoft released the Fall Creators Update.)

Unfortunately, these freezes occur almost randomly and without much useful feedback. This is not only frustrating, but also makes it a lot harder to troubleshoot.

But the good news is, it can be fixed…

Try these fixes

Here are a few fixes that have helped other users resolve their ‘Windows 10 freezes randomly’ problem. You may not need to try them all; just work your way down the list until you find the one that works for you.

  1. Update your drivers 
  2. Clear your computer’s temp files
  3. Run a memory check 
  4. Adjust your virtual memory
  5. Run a disk check
  6. Run System File Checker
  7. Disable C-States in BIOS

Method 1: Update your drivers 

Updating drivers should always be your go-to option when something goes wrong with your computer or system. Whether you choose to update the device drivers manually, using Windows Update, or you use a trusted third party product, it’s essential that you have the latest correct device drivers for your operating system at all times. 

If you’re not comfortable playing with device drivers, we recommend using Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs.

To update your drivers with Driver Easy, just click the Scan Now button, then when it lists the drivers you need to update, click Update. The correct drivers will be downloaded, and you can install them – either manually through Windows or all automatically with Driver Easy Pro.

Check to see if your computer still freezes randomly. If the problem persists, you know your drivers weren’t to blame, and you should try the next fix.

Method 2: Clear your computer’s temp files

If Windows doesn’t have enough space to store temp files, it can slow down or even freeze. So you should clear them regularly.

1) On your keyboard, press Windows key and R at the same time, then in the Run form, type temp and hit Enter. This will invoke Windows Explorer with your Temp folder open, showing you all the temp files on your computer. 

2) Select all the files in the Temp folder and delete them. 

If Windows 10 is still randomly freezing after clearing your temp files, try the next fix.

Method 3: Run a memory check

A faulty memory card is one of the most common causes of computer freezes. So before you invest in a new computer, check to see if your memory card is at fault. Microsoft has a built-in tool to help you do this.

1) On your keyboard, hold the Windows logo key  and press R at the same time to invoke a Run command. Type mdsched.exe in the run box and hit Enter.

2) If you want to check for problems immediately, click Restart now and check for problems(recommended). If you want to check later, click Check for problems the next time I start my computer.


3) Windows will then restart, and you’ll see this page showing the progress of the check and the number of passes it will run on memory.

If you don’t see any errors here, your memory card probably isn’t the problem, and you should try the next fix.

Method 4: Adjust your virtual memory

Virtual memory is basically an extension of your computer’s physical memory. It is a combination of RAM and a portion of your hard drive. If your computer runs out of RAM when performing an intensive task, Windows will dip into virtual memory for temporary file storage. 

1) On your keyboard, press Windows key and Pause/ Break key at the same time. Then choose Advanced System Settings on the left panel. 

2) Go to the Advanced tab, then click Settings

3) Go to the Advanced tab again, and choose Change… in the Virtual memory section. 

4) Ensure the Automatically manage paging file size for all drives checkbox is NOT ticked. 

5) Select your windows drive (the hard drive or partition that has Windows installed on it – usually C:), and enter an Initial size and Maximum size for your virtual memory:

  • Initial size – This value varies, depending on your computer. If you’re not sure what value to use, just enter whatever the number is in the Recommended category. 
  • Maximum size – Don’t set this value too high. It should be about 1.5 times the size of your physical RAM. e.g. A PC with 4 GB (4096 MB) of RAM should have no more than about 6,144 MB virtual memory (4096 MB x 1.5).

Once you’ve entered your virtual memory values, click Set, then click OK to continue. 

If you’re still having problems with Windows 10 hanging after adjusting your , try the next fix.

Method 5: Run Disk Check

If you’ve come this far, it’s time for you to check if your hard disk is at fault. Don’t worry, this is easy to do, because Windows has a built in tool for the job… 

1) Close all open programs and files.

2) Click Start > File Explorer > This PC

3) Locate the hard drive you’d like to check, right-click on it and choose Properties

4) Go to the Tools tab and click Check

5) If your hard disk drive is problem-free, you’ll see this: 

This suggests your hard disk is NOT the problem, and you can move on to the next fix below.

If you DO see errors, it’s possible they’re causing Windows to freeze, and you should consider upgrading your disk.

Method 6: Run System File Checker

Corrupt or missed system files can cause Windows to randomly freeze. But don’t worry, Microsoft makes it easy for you to get your original system files back. It has an in-built tool called System File Checker that will restore any broken or missing system files that could be causing your PC to freeze. Here’s how to use it: 

1) Press the Windows key on your keyboard, then type cmd (DON’T press Enter). Windows will display a list of programs that match your search. Right-click Command Prompt and choose Run as administrator

If prompted to provide administrator permission, click Yes

2) In the black Command Prompt window, type:

sfc /scannow

Then press Enter on your keyboard. 

Windows will scan your system for corrupted files, and attempt to fix any it finds. The results will display in this window, so please leave it open until the operation is complete.

If the scan finds no problems, you know your system files aren’t the cause of Windows 10 randomly freezing, and you can move on to the next fix.

Method 7: Disable C-States in BIOS

“C-States” is short for “CPU States”. They’re basically power saving options – they turn down your system’s voltage, multipliers, etc. so your computer uses as little power as possible when it’s idle. Disabling C-States (turning off the power saving options) can make your computer more stable, and reduce the chance of unexpected problems like random freezing or rebooting. To disable C-States:

1) Restart your computer, and when you see the logo screen (example below), press the Setup key defined by your manufacturer. It should be listed on the logo screen. (Different manufacturers use different keys, but it’s usually F2, F1, Esc, F12, Delete or a combination of these keys.) 

If you’re not fast enough, and the logo screen disappears before you hit the Setup key, just wait for Windows to finish starting up, then restart your computer and try again.

2) Once in your BIOS setup, use the arrow keys on your keyboard to navigate to the main menu. Go to Advanced tab, and choose the CPU Configuration option. 

3) Both C1E Function and Intel(R) C-STATE tech should be Disabled. If they’re not, use your keyboard up and down arrows to navigate the list of options, highlight the setting you want to change, press Enter on your keyboard, then press the up or down arrow on your keyboard to change the value to Disabled.

After changing these settings, save and exit the BIOS settings as per the instructions on your screen, then restart your computer again.
