The Event ID is sometimes accompanied by the Event ID 56 ACPI 2, which further gives you more clues that a driver is faulty. Regardless of the details, some universal solutions have worked for users, and we share them with you in this article.

What is Event ID 56?

Event ID 56 is a generic Windows error that appears when certain events occur. Multiple factors, such as a hardware problem with the computer or a problem with the operating system, can cause this error. One thing that stood out from most reports was that ASUS users were the most affected by the Event ID 56 error. Although the Event ID 56 error can be from a source application popup, some of the general causes include:

Unused audio drivers – According to some users, some audio drivers that have not been in use for a while were the cause of this issue. Incompatible hardware – This could be the issue if your PC has been in use for a while and you’re yet to update your BIOS, especially after updating to a newer version of Windows. Defective CPU – Although it can be hard to detect a faulty CPU, there are some tell-tale symptoms that can help you detect when it is failing. Outdated drivers – It’s always good practice to keep your drivers up-to-date as they keep things running smoothly on your PC.

How do I fix Event ID 56?

Before you embark on the advanced solutions, we recommend that you try the following first, as these preliminary steps could resolve the issue:

Update all your drivers. Disable or uninstall any unused drivers in your system that may be causing incompatibility issues. Run the SFC and DISM commands to ensure you do not have any corrupt files in your system. Roll back any recent Windows updates to ensure it’s not a buggy update causing these issues. Delete your administrator profile, then create a new one, as there are chances it could be corrupt. Remember to backup your files before deleting.

1. Restart the Windows Update service

2. Update BIOS

3. Disable C-States

Disabling C-States is a way to reduce power consumption by turning off parts of the CPU that aren’t being used.  SPONSORED It is important to note that although disabling C-States does not affect the performance of the CPU, it will take a significantly longer time for it to wake up whenever it goes into sleep mode. Apart from these solutions, a handful of users could bypass Event ID 56 by overclocking their CPUs. While this can be beneficial in boosting your PC’s performance, if not monitored, you risk damaging your CPU permanently.  If you go through this route and it works for you, we highly recommend you also install overclocking monitoring software so that the lifespan of your processor is not affected. For those who are unfortunate, perhaps performing a system restore or upgrading your motherboard might help in this situation.
