Hey Kent Bond,

This has been going on from the begining. I did a clean install of Windows 7 (32-bit.) When I look at the Resource Monitor it shows
the System Interrupts - Deferred Procedure Calls and Interrupts Service Routines are running at 45%. When I put a check on the
System Interrupts, down in the Associated Handles and Modules, it shows nothing. What is going on? How can I fix this?
I also get the same problem if I have Windows 7 (64-bit) installed.

My System is a HP Media Center PC m7330n
AMD Athlon 64 X2 Dual Core Processor 4200+ 2.20 GHz
2 GB RAM
ATI Radeon HD 2600 Pro 512 MB
SB Audigy sound card

Thanks....

hello, i"m running windows 8 pro w/mc 64bit cpu3770  quaud core 3.4 -3.9 ghz 24gig mem.

nvidia geforce gtx 750ti 2gigs gpu and the system interrupes-Deferred procedure calls and interrupes service routine on my rig is running at 0.24%,and i think thats high,but after a little research its running at norm,you on the other hand your rig 45% is quit a bit or resources and menory,yes check all your drivers and do update you chipset. just as the guy suggested.

My fix was to uninstall the WiFi card.. then reinstall the driver for it.  System Interupts are no more then 0.9% now.
