Help. Windows using too much RAM

Sep 19, 2011 1:32AM PDT

Hello everyone,

Just bought a new laptop
DELL Inspiron 15R
i3 2310m 2100MHz 4GB RAM 1333 Mhz
Geforce 525m 1Gb. 640 GB HDD
Windows 7 Ultimate 64bit, BitDefender internet security 2012

I have a problem - when I'm installing a game (from iso file mounted via daemon tools or power iso) or uploading via dc++ my RAM usage gradually reaches almost 100% and computer becomes unresponsive (I can barely type this post). After the task is done, RAM goes back to normal, but computer remains a bit laggy for a while. I really don't know what to do. Task manager shows that all processes use 5-20% CPU and about 1GB-1.3GB of memory (normal behavior when Windows idle) . But what uses other ~2.5GB I have no idea. Tried disabling antivirus, some programs to no avail. The games run well Witcher, Deus Ex, Far Cry 2 - Max-High settings.

Please Help, but do not post smart answers like uninstall and reinstall all programs one by one. Yes I have all the drivers, but I might have missed something, so if you know any specific idea what may cause this,
Please share. Thank You

I'd skip using the daemon tools and

Install from CD/DVD next time. I've found that tool to create this issue along with illegal downloads.

Your issue has been seen before and it always seems to come back to what's not stock.

Sorry but using offensive language makes that inevitable.

Re: installing
Sep 22, 2011 10:49PM PDT

With the usual game being expensive and trying enough to spend 100 hours on, it doesn't seem inappropiate to spend 15 minutes to install it without doing anything else on the laptop if that is being slowed down by the install.

Sorry

I can wait 15-30min, but that's not the point. If I see my neighbor being robbed and I want to borrow a vacuum cleaner, I can wait till they finish and then come when my neighbor's home.
That's not guaranteeing that the vacuum will be there...
I want to identify and solve the problem. If I wanted to ignore it, I wouldn't post in forums...

Sorry for the language, but I got frustrated with R.Proffitts reply. Sure I
can stop using software. Even better - I can uninstall windows - all
problems solved. Again sorry for the sarcasm, but I come here for info

Yes it is frustrating. Why?
Sep 23, 2011 3:23AM PDT

Because the item you noted is known to be buggy and do what you noted.

I can only guess that you thought that folk had a cure for that title but if there was you would have found it with a little research.

Since I've run into this title and it's bugs before my advice to use something else. Maybe even the real CD/DVD and install the app.

If you download a file that is compressed multiple levels deep.....often done to send a very large file....and you decompress that file you might find it takes some very serious ram and cpu cycles.

The machine might become quite slow as it tries to decompress to the root.

I recall playing with one of those things and my AV popped up with "Decompression Bomb".
I'll let you run that through google.

Nope
Sep 23, 2011 5:06AM PDT

Nope, not a decompression bomb.
Well something happened and installer does not use all of 4 gigs, only 2-3 now.
When uploading still all 4 gigs (3.8 to be exact). I'm starting to get confused. It could use more CPU. That would closer to normal PC behavior, but come on 10%... Either way my computer gets unresponsive and I think because there is 0 free memory (105 MB standby).
(Idly there's 500-1000mb of free memory, and 1-2GB standby.)
I tried disabling windows indexing. Nothing.
Any other similar services you know of could cause this?

You didn't follow Bob's advice yet, I see.

Burn that iso to a DVD and install from there. Does that help? Then it's some quirk in deamon tools.
If it's the same, I would find another PC to try it on and compare it with. If it's the same there, it's probably the normal behaviour, and nothing special in your PC.

OK
Sep 23, 2011 7:52PM PDT

Alright , I'll try the DVD, but I think then everything will be a OK, since it's not only daemon tools that's acting weird. I'll post you how it goes.
On my friends laptops (one i3 480, ati 6650, other i5 2410m, nvidia 525m - W64 Ultimate both DELL) everything's OK, same programs.

NEW IDEA. I see you wrote ULTIMATE
Sep 24, 2011 1:33AM PDT

I'm unsure if this is some clean install or not but as I have an all too similar Dell i15r with the i5, 6GB RAM and not any sign of the trouble you noted, maybe we can compare notes.

For example, is the Intel RST running? I found it to not be optional.

And no, I don't use that daemon tools app. After some hundred machines with troubles you learn what not to use.

Good idea. Unfortunately...
Sep 24, 2011 4:50AM PDT

Just installed Oblivion from a DVD - no abnormalities, fast and steady.
No, RST is disabled for some time now. I think that partially solved daemon tools problem.
(Similar virtual mounting programs has same problem, stop blaming DT (or windows some tiny process, that's disabled/enabled on my machine somehow doesn't support mounting large files). I think windows stores as much as possible data into RAM, and doesn't think that I would need that memory for other processes. I'll try tampering with windows page file.

Sorry I can't.
Sep 24, 2011 5:01AM PDT

But if you look at daemon tools and Intel's RST you may see some conflict.

I'm unsure why you don't consider daemon tools buggy since it doesn't work with a stock OS as supplied?

Well, I found out that my problem is not application fault, it's Windows.
Tried to copy 4GB file from C: partition to D. Guess what? 95% of memory usage. Searched google - found that few other guys had the same problem. With Vista64 and W764. Topic started in 2003. Unresolved. Unless they're not telling the solution on purpose.
So anyone?

Why is this a 'fault'? RAM is there to use.

Since Windows' Vista and 7 were not around in 2003 I doubt this 'unresolved' problem relates to those.

A 4GB file is huge even by today's standards. Even on my 12GB RAM setup I would expect a whole lot of RAM to be used when copy/pasting such a large file.

Here's a test. Does RAM spike towards 100% when you are copy/pasting medium sized files, eg a couple hundred MB or so? If so then the problem seems to be with your system and not with Windows.

Like Kees says, RAM is there to be used. If it is not utilised, why have it?

Copying a smaller file ~500mb seems OK.
Somehow copying a file (any size) on my old laptop W732bit would slow my system (Core2Duo 2.1Gzh 4GB), but that I could browse the internet and watch a movie at the same time.
In this case my laptop becomes unresponsive till the task is done.

Re: speed
Sep 27, 2011 11:02PM PDT

You're saying that the 32-bit OS on your old laptop was doing this better (faster, less effects on other processes) than the 64-bit OS on your new laptop. Let's accept that as a fact.

This could be caused by:
- different handling (by design?) in the 32- en 64-bit versions of the OS
- different hardware
- different other programs installed or running

Now it's up to you to find the cause.

A good start seems to be to install the 32-bit OS on your current laptop and see how that behaves. Then install the 64-bit OS again, but without any other software. Compare the two. Then install your usual programs and compare again.
Working on one machine excludes the hardware as a possible cause.

It would be interesting to learn about your experiences. Especially if you come to the conclusion that for your use of the machine a 32-bit OS is better than a 64-bit. But also if you find out that one of your other programs is making a mess of it.

Sorry, since Windows 7 was not available.

But let's say the OS has a flaw. How are you going to fix that?
