    High CPU for System Interrupts


      I have a Dell Optiplex 380 and am getting high CPU usage for "System Interrupts" (via Resource Monitor) due to my AMD video card.

      System: Core 2 Duo E7600, Win 7 Pro 64-bit

      Video:  AMD Radeon R7 200


      My system's CPU usage is at 20-35%, with nothing else running.

      I know it is the video card because, when I remove the card and use the video on the MB, the problem disappears.

      I reinstall my R7, downloaded the AMD auto-detect software, reinstall the drivers and the problem is there.


      I have read lots of general stuff about the issue with lots of possible / maybe / it-worked-for-one-guy solutions.

      I have done the disable-all-sound-effects thing.

      I have disabled the AMD audio driver in case it conflicts with the MB audio.

      I got nothing.


      Help Mr Wizard!
