Windows 7: System Interrupts CPU spikes

05 Mar 2012   #1

Windows 7 Ultimate x64
System Interrupts CPU spikes

I was wondering if anyone can help me with fixing a problem of CPU spiking.
The culprit seems to be Deferred procedures and interrupt service calls.

It always spikes between 1-25%...even if there is no program opened
The DPC latency checker runs in green all the time around 129us
How do I fix it, get rid of it and what is causing it?
Thanx in advance

System Interrupts
Hello! I have constant 8% CPU usage in Windows 7. It does not show up under any particular process in Task Manager. Resource Monitor says that it is System Interrupts. I suspect this is a driver issue -- is there a way to get more detail on what is sending interrupts to the CPU?
