    X2 3800+ 939, IDLING at ~20%

    I know it's some sort of strange oxymoron, but I have upgraded my S939 Shuttle (SN95G5) with one of those cheap X2 3800+'s from NewEgg, ran a fresh XP install, updated with AMD X2 drivers, MS Hotfix, AMD Optimization, boot.ini, reg...etc.

    Before and after those updates, my CPU "idles", IE: no programs running, tray empty, fresh reboot, task manager under processes shows System Idle Process at 99%, but switching to the Performance tab, CPU usage is at a consistent 20-30%, CPU 1 blips, but most of that 20-30% is running solid on the second core.

    WTH?!

    Here's a pic of what i'm seeing, I sorted the processes by CPU usage, but you can see at the bottom the 24% usage...

    Eh...

    @i found nemo: It stays this way after a fresh reboot :| I can't find any processes causing it...

    Here's task manager expanded, and sorted by CPU usage. Also the CPU usage on the two cores under the performance tab...

    Do you have any powermanagement software on? I know on my laptop there are options to set how low the utilization on my CPU can go...

    possibly a bios thing? Did you reset cmos before installing dual core and do you have the latest bios?

    No cool and quiet, power management, or idle software as far as I know...

    I used the AMD driver and Dual-Core Optimizer from here: http://www.amd.com/us-en/Processors/..._13118,00.html

    I didn't reset the CMOS before installing dual-core, but I'm pretty sure it reset itself as I had to redo my BIOS settings- I'll try that, as well as check on the latest BIOS...

    You also may want to try it without the dual-core optimizer. I believe in some cases it caused more problems than it helped. . . I could be mistaken here though as I never had to try it myself.

    BIOS updated to latest (sn95s1xd.bin), CMOS cleared, and Dual-Core Optimizer removed.

    Fresh reboot after it all, it persists... :O

    It really doesn't affect anything, just so annoying- like having your speedometer at 20mph when you're stopped :|

    Seems like a hidden process(some malware maybe?) running in background?

    Wouldn't that show up in Task Manager? I can check under services and stop it if need be to see if the usage goes away? Seems odd it would only use the 2nd core though...

    What seems odd is that the idle process reports 99%, you can't have that and 25% CPU usage from something else

    aint it deferred procedure call? IE interrupt conflict/really bad driver/F_component?
    DPC itself isnt showed in taskmgr imho, try Process Explorer from SysInternals

    DPC is probably the one doing the usage.

    One question, what video card do you have in that system ? Nvidia 6800 maybe ?
