CPU load Stuck on 100% load!

Recently my computer is always at 100% even when no apps are running. But as soon as i run Task manager load reduces. This doesnt happen in safe mode. Im sure that this is a virus. When i scan my computer with Avira Antivirus (Free) it doesnt detect anything :(. What do i do?

  2. sounds more like malware.... try downloading malaware bytes - usually inds malware etcthat gets misse by antivirus software
  3. You can list processes cpu usage from commandline:
    http://www.techish.net/windows/get-process-cpu-usage-using-wmi/

    Any processes with CPU time over 50%
    wmic path win32_perfformatteddata_perfproc_process where (PercentProcessorTime ^> 50) get Name, Caption, PercentProcessorTime, IDProcess /format:list

    You can use this to pinpoint the source of the problem and get an id of suspected process.
  4. Im scanning my system now with malawarebytes. but if it doesnt work ill have to reinstall window. I have partioned my current disk into 3 parts - games, video and pictures and OS.

    Is there anyway that i can reinstall windows without harming the other partions (Games and Video and Pictures)?

    If yes how? i am backing up my videos and pictures now. but if i format my games drive then all my save files and all will be wiped...
  5. malawarebytes already found 3 objects! hope this will work cause formatting ur drive and reinstalling windows is a pain...
  6. Probably wouldn't hurt to run a pass or two of Spybot Search and Destroy on it. I've had it find things that MalwareBytes didn't.

    Ill try that is malawarebytes doesnt solve the problem.
  8. I've gotta wonder if all you are seeing is the initial spike of CPU activity when taskmgr opens. It'll show 100% activity for a second before settling down, this is normal. You say the problem goes away when you open taskmgr? Hmmmm...
  9. Installing Windows on your C:\ partition will have no effect on your other partitions.

    Any programs or games installed on those partitions however *may* have to be reinstalled to restore their registry entries. Try each one out first; those that don't launch, simply reinstall over themselves in the same folders. This will keep all customizations, saved files etc.
  10. ahh malawarebytes found 4 objects but it still hasnt solved the problem...
    Ill try Spybot search and destroy but im losing hope.

    OK so can can you guys tell me how to reinstall windows without disturbing other partitions? and is there any way that the virus can be on the non-windows partition.
    Is there anyway to backup my save file in case it gets wiped? I have backed up my mivies, videos etc and my games. but i have alot of games so i dont want to reinstall it.

    As for the virus (suspected) moving to a non-OS partition, it is extremely possible. There are such viruses out there that have been known to infect a pre-boot environment outside of Windows (although they are rare).


    As for backing up your save files, I would recommend consulting the game manufacturer's site as there are ways because I've had luck with doing so in the past with games like Need for Speed: Most Wanted. All I had to do there was go into My Documents folder and then the Saved Games folder and I simply created a backup of it.

    As for not disturbing your other partitions, I would recommend going into Disk Management and see how they are actually sectioned and then be sure to only format (don't delete and recreate) the C: partition when you are reinstalling Windows (if you decide to).
  12. spybot search and destroy didnt fix it :(

    ill have to reinstall windows. i backed up all my save files so thats good. they were in my documents.

    ive never reinstalled windows before. so how do i do it?
  13. OK i reinstalled windows, but in the C partition there is a folder called windows.old can i delete that cause its taking up like 15gb
  14. Yes, you can. You may wish to copy any personal data out of there before deleting.
