High Ram & CPU usage and then Computer Freezes.

aviv258958 · Jan 11, 2015

I am having this problem for about a month now. I tried disabling Ndu, I have tried a lot of things that did not help me.

My OS is running on an SSD (Samsung EVO 120GB)
Secondary OS is running on an HDD (1TB WD) (Bootmanager is also hosted on this HDD)

Computer gets to 80% ram usage and then freezes for about 5 minutes, and then it comes back and all programs report 'disk I/O error'

I have a video that describes the problem as follows (this is what happens after the pc unfreezes which takes about 5minutes and it freezes again after if I don't restart.):

I have tried most of the things I knew of. Searched a lot on google. nothing has fixed my problem yet.

By your hardware specs I don't see anything that should cause any bottlenecking. Have you tried keeping the Task Manager on with Processes tab open and the CPU ticked while using it as usual? Maybe then you can see if a program or process is causing it(like when one activates Maintenance instead of letting it do it when the PC is not in use).

It's not that.
I have like 10% ram usage on my user and all the other 70% ram goes for something that is not listed.

From the looks of your video and screenshot you have something using a lot of page file(swap) also. You could go to Resource Monitor and get a better view from what's causing it. First look in the Memory tab click the Private column and pick the processes that are using the most memory, then click the disk tab and tick the Write column to see what's being written. Also you can right-click and choose Anylize Wait Chain and view what is causing a bottle neck in that process. Like this:View attachment 56431

not so quite sure I got ya, but this is how it looks from here ~

Right now everything looks normal. You do have a lot of programs connected to the internet on that stays in memory and/ logs but that shouldn't be a problem. How often do you shutdown your PC(not sleep or hibernate)). That could help clear suspended processes from your memory buffers. Because mine boots so fast(see my specs), in 17-19 seconds, I shut mine off when I leave the house or go to bed.

I do the same, my pc boots in 20 seconds because of my bootloader, its hosted on the HDD, last time that the bootloader was hosted on SSD pc turned up in 5-6 seconds. I always turn the pc off when I go to bed or when I leave the house.

Are you also using Samsung Magician's RAPID MODE in with your EVO(I use it on my Samsung Pro, I believe the EVOs have it too), and have prefetch/superfetch(lots of logging and writing) turned off? Ok, Lots or little RAM usage isn't the problem really, it's the freezing...keep Resource monitor on the task bar and next time see if you can activate it and use Analyze Wait Chain to see what's(which program or system module) causing it, by looking at Memory also the hard faults column. To see what Hard Faults are go HERE..this is an excerpt:

[h=3]Hard Fault vs. Page Fault[/h]First of all, a "hard fault" was previously called a "page fault" in earlier versions of Windows. Perhaps page faults were more easily understood from the name, too. A hard fault happens when the address in memory of part of a program is no longer in main memory, but has been instead swapped out to the paging file, making the system go looking for it on the hard disk. When this happens a lot, it causes slowdowns and increased hard disk activity. When it happens an awful lot, the possibility of hard disk thrashing arises. That's when a program stops responding, but the hard drive continues to run for an extended period. This has historically been referred to as "getting into the page file."
In this era of relatively large memory, with most PCs having a gigabyte of main memory or more, hard drive thrashing and the problem of getting into the page or swapping file has become rare. However, it's not impossible for a Vista computer with limited resources (too many programs running at a time) to be making a program read data continually to and from the hard disk. Each time this happens, it's a hard fault. A high number per second suggests that something is running very slowly.

I have prefetch / superfetch disabled ( I checked through regedit or something I can't remember ) but on Samsung's Magician it says that it is not disabled?

I have mine set up like this:View attachment 56439 your prefetch is deactivated, the "set" column shows what clicking "will" do, not the status(which would be more logical). I have my hibernate on(for fast boot) but then again I have a 256GB drive for my system, and on modern SSDs, a normal home user will have to replace his PC before the SSD wears out, A must read for SSD owners is the SSD Endurance Experiment at The Tech Report.

You and I have the same set-ups, I have had hibernation mode on and I turned it off because of RAM high usage (it used more ram).
So what do I do to fix those freezes.. I didnt actually get you here.

In post #8 I said

...keep Resource monitor on the task bar and next time see if you can activate it and use Analyze Wait Chain to see what's(which program or system module) causing it, by looking at Memory also the hard faults column.

When the system freezes there's usually a bottleneck somewhere(kind of like when lanes merge from 3 to a single lane when construction is going on a highway). You can see that in the hard faults column(A page fault occurs when a process requests a page in memory and the system can’t find it at the requested location. If the requested page is elsewhere in memory, the fault is called a soft page fault. If the requested page must be retrieved from disk, the fault is called a hard page fault.) . Then just right-click it to analyze the wait chain to see what part of the process is being held up by another process. You then have a choice to suspend(better) to see if the freeze ends, or end the process(not so good when it's a system process). Then at least you can see what's causing the freezes and from there get help or if it's a program you installed and don't really need , uninstall. This is kind of hard for me to explain in words, even though I can do it myself when sitting on a PC.

did you even try a clean boot?? did you try turning off rapid mode? i had a laptop with that drive and no rapid mode on it still was flying speed-wise.. there was absolutely no reason for having rapid mode at all.. and it's another factor for causing conflicts anyway.. so think about not using it honestly..

on the contrary about your high ram usage, there is no reason your ram should be that highly used, here is mine and i have testdisk running, multiple firefox tabs, and programs running and i haven't restarted in days..

unless you are running audio/video editing software or something backup or something that requires that amount of memory.. why is 7gigs being used??

you have something installed on that computer that is causeing conflict..

-when did that freezing start, does it happen after you clean boot..
-do a clean boot.. msconfig(startup) disbable all etc.. (ask if you don't know)

edit*- that also could be bad ram.. you may want to try taking out your ram sticks and only install one.. two.. etc.. lookup how to install ram though, there is a specific way you put it in..(channel 1,2 etc..)
