    Hello Ffrench, and Emko...
    To find help, usually it is best to start your own threads,
    since it is likely it will be assumed that your note is simply a reply to the original post /thread...

    I just stumbled upon your posts because I noticed some activity on this thread...
    and I am interested in helping folks with BSOD issues...

    Read this excellent tutorial for help getting started... https://www.techspot.com/vb/topic33297.html

    So... when you start your own thread...
    Provide your system specs... (motherboard, processor, ram, version and service pack of windows, etc)
    Provide as much detail about what your problem was as you can.
    Provide information regarding any steps you have already taken.
    If you have minidumps, attach the three or four most recent.

    Someone here will notice the new thread, and will get to you as quickly as they can.
    I hope this helps.

    Hello everyone. I stumbled across this thread while searching for a solution to the same issue a customer of mine had also with an XPS 630I. I ran the Dell diagnostics that come with the computer and did a test on the CPU and lo and behold, it comes up with an error while testing the L2 Cache on the processor. Since they were still under warranty, they called up Dell and had the CPU replaced. I havent heard back from them yet but it was just yesterday so we'll see.

    An update - After a brief email exchange with Dell support, during which they had me run some of the Dell diagnostics (no problems reported), they suggested I reload the factory OS image from hard disk, which I completed on 23rd May. Six days later it crashed with the same BSOD "Memory management".

    Now awaiting a telephone callback to resolve this issue...

    Did you they have you run any tests in particular? The ones I did was custom test and I did all the tests on the CPU. If that comes back with nothing, I would run the custom test, select all devices, check the run non-interactive test only checkbox on the right and then run tests.

    Roymondo, I have just answered to another thread with a very similar problem you are facing.

    I have ask for a kernel dump and not a mini-dump. I assume if you did contact dell, they probably ask for the same thing.

    Anyway, if you do have it and can upload it somewhere so I can download it, I can help you.

    If not, here is what i wrote in the other thread on how to create a kernel dump :

    "How to make a kernel dump :
    Go to control panel -> System -> Choose Advanced tab.
    Under "Startup and Recovery" press the Settings button.
    Under System failure -> Write debugging Information -> Choose Kernel Dump.

    You should notice the directory it choose to dump the file. By default it should be dumped at \Windows\memory.dmp file.

    When you finish setting up the kernel dump, just wait for next BSOD. this time it will take much longer to create the dump. When the dump will be created, log in back to your machine. Zip the memory.dmp file and just send it over somehow.

    Memory Managment problems may happen from faulty drivers that courrpt the memory structure. What I will try to find is some evidence that a driver did courrpt it and it was not the memory/hardware fault.
    With that, can you go to command prompt and run the command "fltmc filters" take the output and post it here.

    Good luck,

    Having looked back at their email, the only test they asked me to carry out was the Memory Test.

    As luck would have it, I still have the Kernel dump from the crash on 29th May (it has crashed again since then, but I have also since changed the option to Minidump).

    I am in the process of uploading it (85MB zipped) to an accessible location and will post details here when completed (in an hour or so at current upload speed...

    Thanks for the offer to help - it is really appreciated.

    I have managed to download the dump.

    It will take some time to completely understand the root cause but I do see an hardware related problem. This does not mean it is the hardware fault but may be a device driver handling that specfic hardware.

    In the meanwhile, there is another test I would like you to run.

    There is a tool on your \Windows\System32 called verifer.exe. This tool called driver verifier and on these kind of cases at help to provide a dump just before the problem and not after the problem.

    BE AWARE, verifer will add a SERIOUS slowness to your machine, after getting a minidump you will HAVE to disable it otherwise the slowness will stay.

    how to operate driver verifer : run \windows\system32\verifier.exe

    On the first dialog box, choose "Create Standard settings"
    On the second dialog box, choose "Automatically select drivers bult for older versions of windows"

    Verify you do have ANY driver selects and press finish. Verifer will ask for a reboot.

    After getting the minidump, run verifier.exe again. this time choose "Delete existing settings" if you didn't do this step, verifer will continue running on your machine and will cause serious slowness.

    You may get a very fast BSOD with verifer so you may want to make sure you have access to safe-mode for removing verifer.

    I will continue to look at the dump you provide, but getting the verifier information will be very helpful.

    Thanks for that quick response EZ123!

    I will try the driver verifier tool in a few minutes (halfway through uploading some photos right now :).

    Just one query though - will the verifier trigger a BSOD more or less immediately? I ask this because typically (but not always) the machine runs fine for a few days before crashing, and I don't much fancy having the thing crawling along for days waiting for the BSOD to appear.

    If the problem is somthing happens very soon and the crash is somthing that triggers it (I suspect that) then you should have a crash pretty soon. Not immediately,but may take a day.

    Try run it and if you are not getting any BSOD after couple of hours just disable it.

    It will also be a good idea for you to remove the bullfrog antivirus just before running the tests. antivirus mostly doing somthing wrong and the BSOD may be a false positive in that case. But at also may be the real issue.

    Noted re the Bulldog Antivirus, but I would note that Bulldog is only a recent addition to my system (a month or so). The system originally came with another AV solution (McAfee I think) but I was not happy with that and installed AVG free edition instead pretty much straight away (the machine is now almost 6 months old). The blue screen crashes started soon after I bought the PC, so they easily predate the Bulldog installation.

    But I will try your suggestion anyway. I'll report back here.

    Thanks again

    OK - I've now run the Verifier tool as instructed. I note that there was only one driver listed after the second screen - pxhelp20.sys. Does this provide any pointers to troubleshooting this problem?
  13. EZ123

    EZ123 TS Rookie Posts: 52

    No, its not.
    Verifer works in general but focused on unsigned drivers. pxhelper is not digitially sign.

    Roymondo TS Rookie Topic Starter Posts: 24

    Thanks - By the way, I'm not noticing any slow-down of the computer either.
  15. EZ123

    EZ123 TS Rookie Posts: 52

    it may not slow down because the unsigned drivers are not active. but no worries. it still may give some information on the next blue screen.

  16. Roymondo

    Roymondo TS Rookie Topic Starter Posts: 24

    OK - Will wait and see what happens. When/if it does crash, do I need to do anything to capture the information, or will it be in the minidump? Should I set it to minidump or kernel dump?
  17. Roymondo

    Roymondo TS Rookie Topic Starter Posts: 24

    Didn't have long to wait :-(

    It crashed again - this time while I was playing a 3D game (Ship Simulator 2008, FWIW). I've attached the minidump.

    the zip file is courrpted. you probably need to re-upload it. I do not think you have to zip it because it is one file.

    Bummer. Here it is again (unzipped)

    Nothing new here in this dump. Verifer didn't gave us any results.

    I have been looking today into your kernel dump and as deeper I goes it does seems to be some hardware issue I can't explain.

    It does seems to be some kind of a memory issue. I think you will have to let dell help you here.

    I will try and continue looking into the kernel dump but I do not see any breakthroughs soon.

    Thanks for looking. It is appreciated.

    I have wrote you the last email and then open the kernel dump again. I have noticed somthing strange which may explain somthing but I need one more thing from you.

    Can you post your pagefile settings ? If you can take a screen snapshot it would be the best.

    To go to the pagefile settings go to : Control Panel -> System -> Choose Advanced -> On the Performance section choose Settings.

    On the next dialog choose Advanced -> In the Virtual Memory part choose Settings.

    Take a snapshot of this screen and post it here. If you can also provide information about your hard drives set up it would be helpful.

    Roymondo TS Rookie Topic Starter Posts: 24

    OK. Screenshot of Virtual Memory settings attached.

    The system has a single internal SATA drive, partitioned as C (about 585GB) and D (about 10GB), which is factory setup as a "Recovery" partition. In addition, there is an external 500GB USB drive which is used only for storage of videos, documents etc.

    I may not reply straight away as I am off to bed shortly (got to be up for work in the morning :)

    Dell have emailed me - they have decided that the motherboard must be faulty and want to send an engineer round to replace it.

    I can hardly wait :)

    went away

    The problem is with motherboard (in my case, at least).
    When a Dell technician came and changed it the problem went away. But before that they had changed my HDD and it wasn’t it.
    I've got a 630i and the errors were exactly like those had been described before: I was getting the Blue screen (Memory_Management). The issue appeared the very day the computer was delivered. Never crashed while playing games. Would crash for sure if you were running AVG antivirus. I was getting "Superfetch stopped responding" and "Host Process for Windows Services has stopped working" errors (with flashing screen). Browsers tended to crash as well. I even installed a clean version of Windows 7 (with the same error message on the blue screen).
    I’m sure that the problem is gone because it has been some time and the system hasn’t crashed a single time and the first thing I did was starting AVG Anti-Virus. Before they changed MCB it would crash the first five minutes running. Moreover, browsers stopped crashing and the screen doesn’t flash anymore.
    The guy who bought their 630i on Ebay can either buy a new motherboard (provided that it works fine with other parts) or just ask dell to change motherboard (they’ll still do it if it’s not under warranty but it’ll cost you).
    By the way, I bought mine (630i) in Australia.
    On my630i*com/resources/driversandfirmware (replace * with . ) you can read the following (click on "New users: Click here for an important note regarding your 630i"):
    "Both new and refurbished 630is from Dell can, and occasionally do, arrive with problems, so it's important to check it all out thoroughly. The reason for this is that you only have 21 days from your Sales Invoice date in which to return your system. If anything doesn't seem right, don't hesitate to (first of all) call Dell and notify them of the problem(s), and then also let us know. Unfortunately, some 630is are just lemons, meaning that no matter how much hardware is repeatedly replaced or swapped out, crashes will still happen. If this describes your situation, and you're still within the 21-day return period (U.S.A.) or the 7-day return period (U.K.) from the date of your Sales Invoice, it is highly recommended that you contact Dell and arrange to have your system returned or get a full monetary refund.
    The key difference/benefit in returning a system as opposed to having parts constantly replaced is simply getting rid of a lemon. There have been a number of 630i users (my630i*com/resources/xps_630i_customer_experiences.html) whose systems were literally fraught with BSOD or other errors regardless of how many components were replaced...until they got a completely different 630i. Aside from poltergeists, no-one can explain how replacing all the components isn't successful, and a brand-new unit is--but it does work.
