Extremely high memory usage RRS feed

  • Question

  • Hi there,

    I have been using win 7 64 bit almost a year. What is bothering me is the extremely high memory usage.It happens randomly which sometimes it occurs more than 2 times in a day. I have 4  gb memory installed in my pc and it uses around 1.5gb when its idle (plus several softwares running at the same time like DC++ and sort of things). Suddenly, the memory usage increases to 4 gb and evrything becomes very slow to response and finally it freezes.Usually i'll restart every thing, start spyware scanning and later on it is okay. But recently, even i have restarted my pc, the problem occurs again. I have checked my antivirus didnt do anything about it. This time i'll leave it for several minutes and suddenly the memory usage decreases instantly from 4gb to 900 mb..weird!! i suspected malwares might be the culprits but i couldnt find anything after scanning using spybot and kaspersky...i hope someone can explain this

  • Please post a screenshot of the performance monitor and download RAMMap [1] and run it when you have the high CPU usage. Now save the data as a RMP file. Zip the RMP file and upload the zip to your SkyDrive [2] and post a link here.

  • Hi fhas,

    Remove the spybot and kaspersky(leave the license info) and install Microsoft Security Essentials and observe the behavior.

    Get MSE here: http://www.microsoft.com/security/products/mse.aspx It's free.

    Windows Defender, Kaspersky and Spybot may be conflicting. Security updates and auto scans can spike the memory usage also. Especially Kaspersky.

    If the above helps, then choose which security application that you'd like to use. Kaspersky seems to have become heavy on system and network performance. Choose one and use it. You can also disable Windows Defender if you choose a third party product. The real-time protection conflicts with real-time protection in the third party products.

  • Hi fhas,

     

    Please first check if the issue occurs after disabling the security software. Also, access Clean Boot. If the issue disappears in the Clean Boot environment, you can continue to narrow down which entry is causing the issue.

     

    In the meantime, you can use Performance Monitor in Windows 7 to check the issue: Using Performance Monitor

     

    Besides, here is an article introduces how to optimize Windows 7 for better performance.
