    Angry Random CPU spikes causing annoying stuttering!!

    Hey,

    Just recently I have started to get ~0.5s lockups every few minutes at random intervals. This causes a stuttery mouse, or stuttery music in WinAmp or games. When I looked at the CPU usage I found that this corresponded to little peaks in the graph.



    My full system spec is linked to in my sig. Recent additions have been my new TFT, a Radeon 9800 Pro (and Catalyst 4.2), and possibly something that Norton 2004 has automatically updated?!

    Please someone help me its driving me nuts!

    Cheers,

    Suman

    I tried arranging the processes by CPU usage (so "System Idle Processes" is at the top) and then watching for one task which shoots up the list briefly when Winamp stutters. However after several tries I still didnt spot the offending item

    Virus/worm maybe??

    right click my computer,
    go to manage
    and check the event viewer
    and then look in the application log and system log
    you should be able to see an error at the times when the spike happens

    Ok I think I've nailed it (well at least found the problem anyway). This error consistently pops up ever 3 to 10 minutes (random intervals).



    Anyone know what the hell it means?!

    I don't know what that means, or if it's the problem. When this happened to me it was because my HD had defaulted to PIO mode, it's worth checking that this hasn't happened to you. Have a look in device manager at the IDE channel your disk is on and check it's still in DMA mode.
