Posted problem to virus forum here, title, 'one of six cores at 100%'
Helped by nasdac, but no problem was found. (One of six cores running at 100% Not sure if this is malware.)

The problem, once again, The computer was built about Three months ago, ran fine. It still is running fine, but about a month and a half ago, I noticed core #6 always at about 100% usage. (Except when running combofix, when usage went down to 75%)

I have kernal view turned on in task manager, and the usage does look like kernal usage. (red).

I reflased the BIOS. No change.

I reloaded windows 7, no change.

There are log files in the virus forum.

Thanks for looking.

Also, the resource monitor reports the usage is "Deferred Procedure Calls and Interrupt Service Routines" This appears to be what is using the core.

OK, I found it. When I found that the usage was deferred pro calls... I figured it might be a card I installed. I installed a comm port card when I built the thing, but had not used it yet. I checked in device manager and found only one comm port. There should have been 5. I powered down, pulled the card, and the cpu is back to normal. Can anyone recommend a good comm port card that will play well with my setup? Thanks all!
