I have dell Inspiron 15R, Windows 8.1 preview installed over Windows 8. Recently I started facing memory leak issues in it. It occurs 1-2 times everyday. This is the normal condition, you can see others specs from the image.

3.8GB available of 4GB RAM. enter image description here

Then, it starts showing warning message to restart after continuous usage of 3-4 hours.

2.8GB(approx) available of 4GB RAM. enter image description here

Please note, this issue has only just started occurring, it didn't happen a week ago. There is no process consuming more than 60MB of memory. How do I solve this problem?

This question appears to be off-topic. The users who voted to close gave this specific reason:

  • "Questions about bugs in pre-release/beta software or prototype hardware are off-topic. Bugs in pre-release products are common and even expected, and are often fixed before the final version is released — at which point the question becomes obsolete. Consider reporting these types of problems directly to the product manufacturer." – nerdwaller, Mokubai, mpy, Michael Kjörling

I assume this occurs when no programs are running (although I can see you have applications running in your screen shots). I mean, if you turn on your PC, check the usage, leave it totally alone for 2 hours, does the same error persists? –  Dave Rook Sep 12 '13 at 11:32
    
But it wasn't there initially. It started just a week ago. I haven't tried that. There must be some particular program causing this issue. How do I find that? –  Captain Code Sep 12 '13 at 11:36
    
Trial and error is one thing, or, if it only happened a week ago you need to consider what changes you made (including updates) or what programs you've started using. –  Dave Rook Sep 12 '13 at 11:42
    
I'd start by using Process Explorer to determine what process is actually using all that ram. also, technically this is probably not a leak (undisposed, unused objects, and lots of them), but if it is, it can be isolated to a single program, so –  Frank Thomas Sep 12 '13 at 12:15

@CaptainCode Then please include screenshots showing the memory usage then. Try using Process Explorer running as Administrator when you get the screenshot. If the thing with the memory leak is a running as a Service it may not show up in the normal list. –  Scott Chamberlain Sep 12 '13 at 14:00

use RAMMap to see what is causing high memory usage: http://blogs.technet.com/b/askperf/archive/2010/08/13/introduction-to-the-new-sysinternals-tool-rammap.aspx

You can also use livekd and run !memusage to display the memory usage.

Because you use a Broadcom WIFI device, update the driver to fix the memory leak. The cause of the memory leaks is the buggy application BCMWLTRY.exe .

RAMMap is showing error as "Error refreshing database".. –  Captain Code Sep 13 '13 at 9:44
    
I already reported this to Mark. have you tried the livekd approach? –  magicandre1981 Sep 14 '13 at 7:02
    
I don't understand how to run it. But I found that whenever system shows low memory notification, the Resource Monitor shows that around 1.5GB of RAM is "Modified". How do I find out which process is causing this memory leak? –  Captain Code Sep 17 '13 at 14:26
    
I know that old Broadcom drivers cause such high modified usage. Do you have such an wifi device? –  magicandre1981 Sep 17 '13 at 17:49
    
Yes, I have Broadcom 802.11n Network Adapter, Driver Version 5.100.245.20 but it was working fine earlier. Should I update it? –  Captain Code Sep 18 '13 at 14:32
