cpu z error code 0x5

If you recently installed CPU-Z or upgraded to a newer version and are repeatedly getting error code 0x5 upon launching the utility, the problem is common and easily fixable.

Error code 0x5 on CPU-Z usually arises due to missing permissions, an outdated or corrupt graphics driver, conflicts triggered by the active antivirus, low storage space, and improper app installation.

Before you start troubleshooting things, make sure to restart the PC and install all pending Windows updates. For most of you, this alone should fix the error!

How can I fix CPU-Z error code 0x5?

1. Run CPU-Z with administrative privileges

  1. Right-click on the CPU-Z launcher (.exe file), and select Properties.
  2. Go to the Compatibility tab, and tick the checkbox for Run this program as an administrator.administrator to fix cpu z error code 0x5
  3. Finally, click on Apply and OK to save the changes and then check for improvements.

If the CPU-Z error code 0x5 is due to missing privileges, you will have to launch the program as an administrator. This will grant it the required permissions to effectively run on the PC!

2. Reinstall the graphics driver

  1. Press Windows + X to open the Power User menu, and select Device Manager from the list.
  2. Expand the Display adapters entry, right-click on the active graphics adapter, and select Uninstall device.uninstall graphics driver to fix cpu z error code 0x5

In 2 out of 5 cases, it was an outdated, corrupt, or buggy graphics driver to blame for the CPU-Z error code 0x5. So, all you have to do is update the graphics driver!

I recommend manually installing the latest graphics driver from the manufacturer’s official website since this gets you the newest version each time. Here are the direct links to the driver downloads page for each:

Often, the CPU-Z error code 0x5 shows up on Windows when your PC has low available storage. In this case, you can run Disk Cleanup and free up storage space.

Also, I recommend enabling Storage Sense, which automatically deletes non-critical files on a regular basis.

5. Install another version of CPU-Z

  1. Press Windows + R to open Run, type appwiz.cpl in the text field, and hit Enter.
  2. Select CPU-Z from the list of applications, note down the currently installed version, and click Uninstall.uninstall to fix cpu z error code 0x5
