Hi,

I have just recently installed Windows 7 Professional on my machine and I am having a problem with a process called System Interrupts using alot (25% approximately) of CPU.

I have tried several supposed fixes i have found here and on other forums but have not solved the issue.

I am at wits end.

My computer got so slow that the mouse was slow and jerky and I had to reboot. System interrupts was at about 30% CPU time. My PC is now with 5 days uptime and the bug seems to have disappeared. The following solution seems to solve the issue :

  1. Right-click on the speaker icon
  2. Select playback devices
  3. Click on the speaker properties
  4. Go to the enhancements Tab
  5. Click Disable All Sound Effects
  6. Click OK. You're done!

The sound enhancements seem for some reason to cause the problem even when not used. So disable them following the procedure above. Good luck!

    André,

    I notice that this is an old thread so I hope I will still be able to raise you for a response?

    I have attempted to follow your excellent guide, I get as far as opening DLC_Interrupts viewer but I can't see exactly how or where to open the graph with the viewer that shows "DPC CPU Usage" or "Interrupt CPU Usage"?

    So to be clear, I can see other graphs, just none called exactly the above names.

    Many thanks. Daniel.

    Right-clicked speaker icon and found Realtek-microphone active instead of stereomix. I switched and cpu usage dropped, from a constant twelve-ish percent,  to zero.

    Stefanos, thanks.  It helped a lot, though I can't imagine why.
