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!

Thanks.
