What is causing my system interrupts?
Disable the device and check out “System interrupts” in Task Manager. A failing power supply (or laptop battery) can cause a spike in the CPU use of “System interrupts” and so can a failing hard drive. You can test your hard drives with Windows’ built in Check Disk tool or with a good third-party S.M.A.R.T.
What process interrupts?
