    As indicated in the title, every now and then my computer becomes extremely choppy and slow. When I look at my processes there is multiple svchost.exe's running, but there is one that is using anywhere from 60-99% of the CPU and taking up a hefty amount of memory, up to 85MB. I searched around on the internet but the "answers" are very diverse and vague. Oddly, this problem only seemed to happen late at night at first when I am usually gaming, around midnight. (DotA anyone?) However, recently it has been happening earlier and earlier. Because of the nature of this problem I fear it has something to do with the hardware, which sucks because I'm a poor college student. If no one here can solve this problem I will try formatting, and if that doesn't solve it I may splurge for some new RAM in an attempt to solve it. Thank you for your time and help. All input appreciated.

    Antivirus update/scan? Windows creating a restore point? Check your scheduled tasks. Otherwise I would dump most of your bootup programs from MSCONFIG and try to isolate which app it is.

    It's probably not a hardware problem.

    Speaking of anti-virus, you do have one installed and updated right? I know that a few viruses pop out a process called SCVHOST (or something similar).
    Also couldn't hurt to run something like spybot or ad-aware.

    That's because some of them are important for windows to work correctly.

    Run spyware removers? Kill svchost? Reformat????

    Geez guys. How about at least taking the patients temperature before you sign him up for surgury? I'm surprised no one suggested a sledgehammer yet.

    For starters find out what processes are in the svchost that you are worried about.

    Run "tasklist /svc" from a command prompt and compare the process ID to the process ID in task manager that is busy. Use View | select colums.. if you don't see PID listed in task manager.

    Seems to be a problem with some updates to Windows. Try and get the very latest updates. It's the svchost.exe that takes care of the visual styles, as ending the process will slowly screw up the visual styles until Windows restarts the process again. I've seen svchost.exe at 99% on almost every computer I've worked with the past couple weeks. But I've never seen it on my own computers at home, and I think it's because I have visual styles turned off on them all.

    But getting the latest updates seems to help out a lot.

    To revive an old topic: does anyone know the fix for this? I've got this issue as well (though it doesn't consume CPU time, it consumes around 80 megs of RAM) and I'm able to kill it in task manager.

    I'm running Kaspersky Security Suite 6....and I've gotten no real notifications. A adware scan is running right now, and I'm going to run a virus scan again afterwards.


    Edit -

    When using IE7 and the windows update page was running a scan, it jumped 40 megs (from 26 megs RAM to 60 megs) - is IE 7 the cause?

    I've seen this a number of times lately, and found that somehow the windows update service is causing the problem. Disabling that service resolved it for me, but I was not able to find a good fix for it. On those systems I switched to using Autopatcher XP to get my windows updates, because even if I went to the update site manually, it would peg the CPU and I could not get the updates to complete.
