In short, a system interruption isn't a standalone task but a signal about how much CPU time is being taken. Any device needing the processor uses interrupts to pause its work and let other hardware take over. This happens with many everyday tools like typing or moving a mouse—when your computer slows down, shaking the mouse can actually worsen performance because the system must constantly adjust focus.
Significant interrupt usage occurs in areas beyond simple input devices: most built-in sound chips rely heavily on interrupts for processing. If you have a dedicated sound card, it typically manages audio tasks itself, especially on higher-end models. Early sound cards had a major impact on gaming and high-quality audio, but that effect is now minimal.
If you're interested in the technical side, these components are often called Digital Signal Processors. USB devices are inexpensive because they require CPU power; unlike SATA or newer connectors like M.2, USB isn't used internally for storage connections. Instead, SATA or M.2 drives connect directly to PCI-E, which includes a controller chip that adds cost.
If you remove USB peripherals—like flash drives, printers, or hubs—you may notice improvement. This usually points to driver issues rather than hardware faults. Often, the problem lies in outdated or conflicting drivers. Clearing them, restarting, and reinstalling the latest versions can resolve many issues.
For graphics cards, especially Nvidia models visible in Task Manager, focus on updating drivers only for the graphics card itself. Avoid installing extra software like GeForce Experience or 3D Vision. A clean install may help.
Also check mouse and keyboard drivers; uninstalling them and restarting can sometimes fix the problem. If none of these steps work, the issue is likely driver-related.
