How do I fix The semaphore cannot be set again error?
1. Repair or reinstall a program
The first thing that you should do when a certain program crashes followed by the system error code 103, is to reinstall it. Certain applications allow you to restore them, and that’s a preferred solution. With that procedure, you might retain complete settings and configuration of the program, while retrieving essential files. However, if uninstallation is the only available solution, we advise you to use a third-party tool to clean up registry inputs of the given program. In addition, make sure to delete all of the remaining files after the uninstallation is complete. That way you can start from a scratch, and hopefully, avoid a future occurrence of the system errors. If the program at hand isn’t solved after the reinstallation, you should turn to additional steps. Maybe the gravity of the error is above a corrupted installation file of a single program.

With the introduction of forced updates in Windows 10, drivers suddenly become a problem. But, we don’t want to neglect the fact that Windows has always been prone to driver issues. SPONSORED Those problems may seem insignificant at first sight, but that’s not the case. In order to have the optimal system performance, you need to obtain, install, and timely update drivers. This goes especially for the main drivers’ list, which includes GPU, sound, network adapters, etc. The system error ‘ERROR_TOO_MANY_SEM_REQUESTS 103’ can be occasionally inflicted by the faulty driver that somehow relates to a troubled program. As we already stated so many times, it’s essential to download and install only trusted drivers from official sites.

So, if the error 103 is still there, even though you’ve performed previous steps, you should start System Restore and give it a try. It proved helpful on various occasions, and it might be just enough to relieve you of the error at hand. Of course, if System Restore is enabled, and it should be by default.

After some time, with the extensive use and various changes within the system, possible malware infections and registry errors, your system should be renewed. However, we strongly advise you to backup your data and license key before you move to reinstallation. And no, it’s not wise to use an upgrade over clean reinstall. You may preserve your data and installed apps and settings, but there’s a chance that the same error will occur again.
