High CPU Usage by System Interrupts – Fix

"System Interrupts" is a placeholder that shows how much CPU is being used by hardware drivers. If it's above 5%, you have a failing driver. Againly fixes this automatically by profiling your driver latency (DPC) and identifying the offender.

Why this happens

Outdated NIC Driver: Your Wi-Fi or Ethernet card is firing too many "Interrupt Requests."
USB Device Conflict: A cheap USB hub or dying external drive is spamming the CPU.
BIOS Power States: Advanced C-States in your BIOS are causing CPU timing delays.

Fix it manually

Unplug USB Devices: Remove everything except your mouse/keyboard and see if the CPU usage drops.
Disable Network Adapters: Try disabling Wi-Fi and using Ethernet (or vice versa) to isolate the card.
Run LatencyMon: Download a tool to see exactly which .sys file is causing the delay.

Fix it automatically with Againly
