One core pegged at 70-100% usage at all times

Hey, I recently started having issues w/ my proc (Athlon 64 x2 5000+ @ stock speeds) as you can probably tell from the title of the thread.

Usage:

Processes:

I find it really strange that not a single process is using more than 1-2% of CPU. (Except System Idle Process, but that's normal) I've scanned for viruses first using AVG, then Kapersky, but nothing came up... Tried updating / rolling back any recent drivers to no avail... I'm wondering if anyone else has some suggestions as to what the cause of this may be?

Hi rgeist554,

I have you tried the free-ware utility Process Explorer (Google)?? It will show show you way more information about what is sucking up your CPU... Windows task manager is dogies do-do's... I think you will find it is interrupts or DPCs that are using up all that CPU time (which Process Explorer will show)...

I have actually started using System Restore (I kid you not!!) since I started using Windows x64. Since I found the OS is so much less stable than the 32-bit version... It could be useful for your problems!!

'dxdiag' Windows utility is supposed to detect driver conflicts but I have never found it terribly useful!!

It will be a nice chip once you sort that out.
I have mine up to 3150ish with ease on stock voltage.
IMO probably the best bang for the buck chip there is.

i have the exact same problem mine occurs whenever i use leadtek's winfast pvr2 to record programs to my hd when i finish recording i reboot and all is good until the next time. i think it may be a recording codec problem because i can watch tv with no issues long as i don't record. it hasn't been enough of a pain in the a$$ to force me to hunt it down so please let us know how it turns out. good luck
