4 days ago I uninstalled Avast and installed another security software (Avira) , but the problem occured again And about Tune Up utilities : I Installed this software 1 day ago but this problem started for me 2 weeks ago with no luck in solving it yet maybe I'll try disabling other services

Memory Usage Goes Up Gradually (Memory Leak) When I starting the Windows (in the first few hours) everything is normal But after 1 day or 2 (sooner or later) the amount of available memory gradually goes down and the physical memory usage increasing. This increasing, continues until the memory usage reaches near the 88% and at that point , there isn't any memory available to operate any software . Also when memory reaches that point, I can't access any drive in the HDD; because everytime I want to open any folder, the following error appears : c:\ is not accessible. Insufficient system resources exist to complete the requested service At this point, I even can't shutdown or restart Windows normally; I must restart windows manually by pressing the restart button. after restart, everything goes to normal again; but this problem appears again and again ... (I had to restart Windows every 1 or 2 days) here is the screenshots of processes and performance tabs in the Task Manager (at 88% memory usage) You can see that there is no software(application) that uses this amount of memory : my system : ------------------------ OS : Windows 7 Ultimate x86 Cpu : Intel P4 3.0GHz Vga : nVidia 6600 MB : Gigabyte GA-8I915G Duo PSU : Corsair 750W RAM : 2GB DDR-400 Transcend (I have these memories for 2 years) Physical Memory: 2000 mb Paging File: 2000 mb Virtual Memory: 6000 mb I already did the following actions but unfortunately none of them helped me : 0- using some optimizing and freeing softwares like (Memory Booster Gold - RAM Saver Pro - CleanMem) 1- Scanning my computer with antivirus and antispywares 2- Changing antivirus software 3- Updating windows with all updates available via Windows Update 4- Updating drivers of all hardwares 5- Downloading and installing the following hotfixes that are related to memory leak : http://support.microsoft.com/kb/976658 http://support.microsoft.com/kb/977357 http://support.microsoft.com/kb/978042 http://support.microsoft.com/kb/978155 http://support.microsoft.com/kb/979223 6- Using CClenaer for clearing everything and using memtest86+ for finding any possible error in memory And here is screenshot from Process Explore (from Sysinternals Suite) at 90% memory usage : So is there anything that I can do to solve this problem ? any solution ? hotfixe ? trick ? suggestion ? anything ? ...
