When to Call a Technician

 Even after running antivirus scans, clearing temporary files, and uninstalling unused applications, a computer can still feel sluggish if deeper underlying hardware or background bottlenecks remain. 

 A Blue Screen of Death (BSoD), officially known as a stop error, occurs when the Windows operating system encounters a critical condition it cannot safely recover from, forcing an immediate system shutdown to prevent data corruption.  

 Random computer freezes—where the screen suddenly locks up, inputs stop responding, and audio loops or cuts out entirely—are among the most frustrating issues to diagnose because they rarely leave behind a helpful error message.  

 When applications take several minutes just to launch, it typically points to severe resource contention, severe disk bottlenecks, or deep-seated background software conflicts. 

 Physical clicking, ticking, or grinding noises emanating from a computer are often the most urgent acoustic warning signs, signaling that a mechanical component is experiencing physical stress or imminent failure. 

 Suspecting a hardware failure is often triggered by erratic system behavior, such as sudden and unexplainable crashes, persistent blue screens, strange physical noises, or components failing to respond altogether.
