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!

    Have you followed my guide and used xperf to make a trace when the spikes happen? Do you see which driver is causing it?

    I also have been having the same issue with Windows 7 Ultimate. Everything is up to date, drivers, windows updates. It seems to be a random event, but it happens every day, I can't predict how it happens or what program causes the issue.
