Sometimes Microsoft Windows gives an error while formatting Windows. If you happen to come across that, then use Fix: Windows was Unable to Complete the Formatting to complete the task.
8. Get A New PSU
Finally, if all else fails, you can try to replace some key components, such as the PSU. The PSU is the Power Supply Unit and is sometimes the core cause of this error. It would help if you got it replaced with a new one. Or better yet, buy one from a different brand, so you don’t run into the issue again.
Your first step should be to identify what’s causing the problem. It could be your motherboard, PSU, or chipset. If you cannot tell through experimentation, you might need to send it to a computer repair store.
9. Replace The Motherboard
In some cases, the motherboard is faulty and needs to be replaced. It’s unlikely, but some inherent issues with specific motherboard models may cause the error. In particular, the Z170 board has been reported to have the Event ID 56 issue. However, other motherboards from the Z series and other manufacturers are also experiencing this error.
Go to a repair shop or manually try to find out if the motherboard is the issue. Then, replace it with a different make and model.
10. Replace The CPU
Sometimes, the CPU can also be a problem. Some users have found that their Intel Core i5 6600k was faulty and had to be replaced. Although CPU defects are rare, they are not impossible. Replacing the CPU with a new one or one from a different brand should be your last resort. And you should bring your computer into a repair shop to determine what’s causing the problem.
