When your Windows computer is lagging and bugging all of a sudden, there may be many factors that result in this frustrating issue.
You should address these potential causes to restore your computer’s performance and ensure a smooth user experience.
One possible culprit behind the sudden lag and glitches is the presence of malware on your computer. Malicious software can infiltrate your system, consuming valuable resources and causing your computer to slow down.
Another factor that can contribute to the problem is a corrupted file within the system processes. These corrupted files can disrupt the normal operation of your computer, leading to performance issues.
In such cases, running a thorough system scan or using built-in Windows repair tools, such as System File Checker (SFC) or Deployment Image Servicing and Management (DISM), can help identify and fix any corrupted files.
Additionally, overall system bugs can also cause your Windows computer to lag and behave erratically. These bugs can arise from software conflicts, outdated drivers, or compatibility issues.
