Random CPU spikes

  1. Hey all,

    I'm experiencing an annoying problem during online MMORPG gaming.

    For some reason, CPU spikes are going up significantly at random times.
    Sometimes it starts to spike after 1-2 minute(s), other times it can take up to 10 minutes.
    The spike duration is usually 10-20 seconds. This is very annoying.

    I already tried the folllowing things;
    • Full CHKDSK
    • Defragmentation
    • Full virus & malware scan with aVast! and MBAM
    • Uninstalling unnecessary/rarely used programs
    • Running CCleaner
    • Running EUSING Registry Cleaner

    Nothing helped.

    I also tried to disable the antivirus, firewall, and Windows Update temporary, but that didn't help either.
    The game is Perfect World International.

    Whenever I re-install Windows 7, the CPU issue does not occur, but it does occur after a few days, and I don't feel like re-installing my OS all the time.
    I'm looking for a permanent fix.

    Random CPU spikes often mean some software you had no idea was able to run 'unrequested' is activating. This could be just checking for upadates of e.g. java, active-x, and countless others.

    You need to check over all the software installed and examine it's setup for where you can disable 'automatically check for updates'. Or just use the highly-repected software Seconia PSI to ensure everything is actually updated, with the bonus of getting a list of what is installed.

    I did a scan with Seconia PSI and I got this message:

    Secunia System Score : 100%

    All my software seems to be up to date.

    Two words: Process Explorer

    You can take a quick read Tip: Get more accurate CPU usage data using Process Explorer vs. Task Manager as well as looking at the links to other thread examples about others who used it to figure out CPU usage questions

    /* EDIT */
    To start, suggest you run it minimized to your notification tray where it displays / you can see CPU spikes in a near real-time graph of your machine CPU usage. Just hover your mouse over the spike in its graph and it tells you what process is using highest CPU at that moment in time. It could well be an update check and.or download from Java, your A/V, etc.

    p.p.s IMO: Process Explorer is the best thing since sliced bread :) (and certainly the most powerful single tool i've ever seen) I've been using it for many years and still only know how to use and interpret a fraction of what it can tell you about usage and what;s happening on your machine)
