    At the time i was using a Creative Soundblaster Audigy SE 7.1.
    Anyway after browsing numerous forums i found the fix and since then i have had no issues what so ever.
    What you do is this,

    1. Right click speakericon in bottom right of the taskbar. Select "Playback Devices".
    2. Left click "Speakers/Creative SB X-Fi/Default Device" then click Properties.
    3. Click on the Sound Blaster tab, And tick the "Disable Sound Blaster Enhancements" box.

    First : Every time I launch TuneUp Utilities 2010 , It shows me the following error about deleted prefetch folder :



    Second - I found something important related to my problem:

    Each time I use my hard drives (copying, cutting, writing, downloading files on any of my 3 hard disks) , the speed of memory leak , increasing.(the memory usage goes up more quickly)
    It seems that the source of my problem is related to H.D.Ds.
    I already defragged all of my hard disks but it didn't help.
    Any other solution ?

    Ok this smells like a driver issue. Are your drivers up to date? Also, are you using any sort of RAID (particularly 'hardware' based, a la softraid)?

    I haven't spent any time with Win7 as opposed to 2K8R2 yet but that NonPaged figure of 1460MB definitely looks like the problem.

    Finding the cause is the tricky bit. PoolMon (which I think you have to get from the Windows Driver Kit for 7.0 ws or svr) can sometimes help a little in that it will tell you which memory tag is responsible, but getting from that to the actually culprit hasn't ever been easy or indeed possible for me... it can be rocket science-ish.

    NonPaged pool leaks have been rare for me compared to Paged pool leaks. Only time I've seen one it was some dodgy printer monitoring s/w that only ran, and steadily leaked, when someone was logged on.

    I already used that poolmon.exe too (here is the screenshots at 88% memory usage) :

    OK - At last I found the cause of this problem and fixed it.
    A file named multikey.sys in the (windows\system32\driver) folder made the memory leaks and after deleting it , everything went back to normal.
    (I used the poolmon.exe software to found this file (with poolmon.exe /c parameter))

    Thanks to everyone helped me here

    Googling the file name would suggest the offending driver is a trojan too?
