Out Of Memory

I have a ~5 year old HP desktop PC. It came with Win 7, upgraded to
Win 10 maybe five months ago.

I have had 16GB of RAM installed ,for many years! Yet recently,
several times a week, I get a Windows memory warning. A Microsoft
triangle appears, alerting me that I am low on memory and I noting
that I need to close programs. Soon there after, even before I have
the opportunity to close any programs, my PC will crash (screen goes
black). Then I always need to do a cold re-boot.

I have run a up to date virus checker and have repeatedly run MalWare
Bytes; to verify I do not have malware? No issue detected.

What could be the root cause of my recurring Low Memory problem? I
know that I have NO idea?

Could be bad memory allocation, which AFAIK is combination of OS and
Program behaviour. Could be that you don't have all 16GB of RAM
accessible, which would be a hardware failure.

So:
Have you updated all of your programs? Have you checked that all your
RAM is good?


Check in task manager performance and see how much memory is being used.

In my case running Win 10 I am using 1.8 GB with only TBird running.

Here are two good places to start:

Memory is consumed in different ways.

Main memory
Paged pool
Non-paged pool

To name a few.

You would need to know what was running out,
to fix it.

You could have a play with this. Leave it
running, flip over quickly when the dialog appears.

https://technet.microsoft.com/en-us/sysinternals/rammap

On the same site is Process Explorer, another useful program.

I don't know if there is an up to date "poolmon"
available or not.

http://forum.sysinternals.com/poolmon_topic14611.html

The Task Manager on WinXP provided a little more info.
It had pool numbers. I'm not sure the later OSes do,
and perhaps it is because the pool section is that
much larger. The pool available on WinXP is tiny.

It could be your trolling and changing your nyms: Dave B, ~BD~ Dave C,
****er, Cock-Sucker, etc etc.

Both Belarc and Task Manager show that I have 16 GB installed.

I have no idea whom you are referring to, it is not myself. My real
name is Dave C, which I use to post this PC question.

I have made infrequent posts on this site, Win 7, a tax and two home
improvement sites. I have often received most valuable advice, on all
of those sites - which I make a point of acknowleding. As in the past,
I am now in the process of implimenting the suggestions by the other
responders, regarding my low mem issue.

I do read daily, the many posts by others on those noted sites. I have
learned a lot - from PC to home repair as I read posts from others.

It IS someone else, not myself, that you have an issue. This is the
ONLY site I posed my low mem question.

Sorry, have a nice day!! - dave c

Disregard the attack Dave C. "Good Guy" is an insecure jerk who only
know a lot of foul words and is mad at the world. To him there is no
good in the world.

There are a lot of people on this newsgroup who are here to ask
legitimate questions and others to provide valid answers.

Download & run the Sysinternals "Process Explorer" (now owned by MS, no
installation needed). If you pick the "Select Columns" option under the
View menu, and ensure that "Virtual Size" (that's all the memory, real
or virtual, allocated to each process) and "Working Set" (that's the
memory not currently swapped out but in physical RAM) you'll see which
processes are greedy, especially if you click the column header to sort
(toggles up or down) by those values.

If an application asks for memory from the "heap", and the developer has
forgotten to release it when no longer needed, then the total memory
allocation just keeps on growing. Called a "memory leak".

Thanks, for a resolution to my mem issue. After I followed your most
helpful suggestions, I have not had a recurrence of the noted PC
crash. It used to crash near daily, now not once for several days.

Thanks a lot (BTW: this a real Dave C)

Two suspects to check:

(1) Thunderbird

(2) Browser(s) with multiple tabs open.

Oh, and do you have swapping enabled? That is, more virtual memory than
real memory?
