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!

    i was having the same problems with system interrupts, what worked for me is going into device manager and system devices and disable the high definition audio controller, once i did this my problem has gone, but remeber when you reboot the device enables again so you will need to disbale it again

    These components are morethan enough...to give a decent performance level

    What is NOT known, however is.....what amount od RAM is being used!

    If it ONLY 2 Gig of RAM, this easily explains 'why' the CPU Usage is so high.

    4 Gig, max, for a 32-bit OS.

    8 Gig +, for a 64-bit OS.

    Standard equation for either OS.

    The CPU is working over-time....to make up for the LACK of RAM.

    If the RAM is 4 GIG, the hard-drive can be really 'choked up'.....with 'cookies',

    These certainly will slow any computer down, cause high CPU usage in the same process.

    A good DEFRAG certainly won't go astray, either.

    Good maintenance habits will alway make any computer work better, faster.

    i think it's a problem with ntosKernel, ACPI.sys and Nvidia drivers. and every solution searched in "google" doesn't work, including clean format, exchanged drivers, reset, downgrade and upgrade bios, clean boot, disabled almost every device including nvidia drivers,

    Some users report the bug in win8, but I'm using win7 x64, maybe it's time to test win7 x32 but using only 4gb of ram.

    Also i changed the two ram slot with a GSkill 2x4gb when i bought my laptop.
