Hey guys, I'm completely thrown by a RAM leak issue I've been experiencing over the last few weeks. Essentially, whenever Windows XP is operating in normal mode (as opposed to safe mode, where the drain does not occur), about 5 megabytes of RAM are lost from the pool of available general RAM every minute (as per task manager and cacheman). This occurs regardless of what I am doing in the process--just leaving the computer following logging in does not avert the degradation. I have heard of memory leaks in software before, but the bizzarre part of the story is that no software (as surveyed through task manager)/process actually uses increased amounts of RAM (about 5 MB/second increase). If left for a few hours, all 3 GB of my physical RAM are swallowed up, making the computer unusable (I have virtual ram set at 4.2 GB also). I used both the Windows Task Manager with 'show all users' processes' turned on and Process Explorer, but the sum total of the processes' RAM use is still not even remotely close to total expenditure. Here are the steps taken so far to try and find the source of my troubles: 1. Ran a multitude of virus and spyware checks, including AVG, Pc Cillin, some online tests--nothing found. 2. Ran a process explorer to find suspicious processes, disabled non-essential startup processes. Then manually shut off all processes that weren't listed as 'system'. 3. Uninstalled recently installed software, including a video codec, bluetooth software and miscellaneous programs. 4. Logged into safemode, noted no memory degradation--thus leading me to believe it may be a Windows core process of some sort doing this. Any help would be great--this is driving me rather crazy! My specs are below: FX 60 Dual Core AMD 3 GB PC 3200 RAM 2 Nvidia 7900 GS in SLI Windows XP SP2 X-FI Pro soundcard All the latest drivers. I do not believe this is hardware related as nothing has been added in the recent past, but I suppose you know better. Thank you in advance for your help.
