Your PC cannot execute commands or processes, so it cannot complete the requests without causing errors and slowing down the computer. If you’ve encountered any of these errors, we have compiled a handful of solutions that have worked for other users.

What is a hard error?

The unknown hard error is the most common message you’ll see while working with your computer. It’s usually accompanied by a process ranging from applications to services.  For most users, closing the prompt made things go back to normal, but for the unlucky ones, they were plagued by a black screen, the disappearance of desktop icons and their PCs were generally unusable. Some of the common triggers for this error include:

Software bugs – Some software bugs may cause the system to crash and generate an unknown hard error. Hardware problems – If your hardware is broken or damaged, it can also generate an unknown hard error. Some symptoms of HDD failure are easy to detect. Virus infection – Viruses can cause this type of problem because they interfere with the normal function of the operating system and prevent it from running properly. Problematic Windows update – Windows Update is a service that automatically checks for quality updates, critical updates, and other important fixes to your computer. If an update fails to install, you’ll see an error message like this. Corrupt system files – The most common system file that causes the unknown hard error is a corrupt Windows Registry.
