Why do I get a blue screen using USB communication?

Hello,
My problem is that sometimes I get a blue screen using USB communication. I guess that most of the time the problem is an overflow in memory, so I read all the data that is on the port with which I communicate. I read two ports so there are two similar VIs that are used. There is how I do it:
I also communicate with a logger to acquire 16 channels. I read the information from the logger in two different parts of the program at the same time. Maybe this can cause an issue, but could it cause a blue screen? This is how I do it:
I once had a blue screen after the VI was closed, so there is how I manage to close the communication when I quit:
Do you think there can be any problem coming from one of these parts of my LV project? If not, what else can cause a blue screen in LabVIEW?

Are you using USB to GPIB (doubtful because you are using bytes at port)? But, just inc ase, I had this problem also with USB to GPIB, and it ended up being a driver issue I believe. If you are using USB to GPIB driver that was released with LV2012, search for the latest 2012 driver on NIs site, download it, and use that. See if it fixes your problem

  • Why can't I access my own wifi? why do I get a blue screen on start up or after watching a netflix movie, and why is it getting so hot?

    My mac has been showing a blue screen on start up and before shut down, especially after netflix. Is it silverlight? Why can't I get on my own wifi? It defaults to a linkys public network, I try to access the secure network, type my password, enter, and I get connection timeout.

  • Why am I getting a blue screen during windows support software installation?

    After intalling windows 7 x64 (using boot camp 5.1), when I come to install windows support software to set up apple drivers for windows to run on my MacBook pro (late 2013), after installing a good number of drivers, I get suddenly a blue screen!....
    What can I do, once windows is not strting up? It started well, but wth no proper drivers. Thanks.

    I guess the first thing I would do would be to boot up using the original installation DVD and correct the permissions. That may not be the problem at all, it could be an incomplete upgrade install but at least you would know it isn't a permissions problem. I'd also run or verify the hard disk using this method.
    How is it done? Turn machine on. Insert DVD 1 of the Install Disks, restart the machine, hold down the Command and the C keys (that tells the machine to look to the Rom drive and boot from it). Once it is up (will take a long minute or so...) go up to the top left where the install menu buttons are listed, look for the disk utility and run it. Tell it to verify and repair the disk and repair the permissions. Once done, quit the Disk Utility and select the restart option. Wait to see if your original desktop comes back.
    If not, then you'll need to either "back out" the upgrade you installed or install your backup. If you don't have a backup you'll probably have to re-install OS X all over again (and probably lose all your previous data, apps, etc.). Let's hope it clears up first before you have to re-install.

  • Why do I get a blue screen when I use the NIDAQ driver.

    I get IRQL_NOT_LESS_OR_EQUAL.
    Address fc792324 has base at fc6f8000 Nidaq32.sys and Address fc7028e3 has base at fc6f8000 Nidaq32.sys.
    The system is running on Windows NT 4.0. The application is built using Application Builder and LabView 5.1.1. The NIDAQ 6.9.0 is used.
    Please help me.

    uffe:
    You seek...Yoda...Help you...I...will..
    This is a kernel mode problem with your NIDAQ32.SYS driver. I believe
    that you can pretty much rule out problems with LV5.1.1 or app
    builder. Your problem
    You have run into a classic BSOD message. It may not always occur so
    it can be really frustrating to diagnose. There may be some
    workarounds you can implement at the application level but it still
    needs to be fixed at the kernel (O/S) level so you're going to need to
    contact NI.
    I've had this same problem error message in the past but not with DAQ
    cards. As I recall, in one case there was a problem with a spinlock
    in the SCSI driver (.sys) file which protected access to the hardware
    I was using.
    What is a spin lock? A spin lock is a special synchronization
    construct used by device driver developers to protect access to
    critical sections of their code usually for hardware access. It is
    the kernel mode equivalent to a VISA resource lock or a semaphore in
    LabVIEW.
    For more on spin locks see:
    http://msdn.microsoft.com/library/default.asp?url=/library/en-us/kmarch/hh/kmarch/k101_97hu.asp
    Work-around Possibility #1: Do you have two different parts of your
    code trying to access the DAQ card simultaneously? If so, providing
    your own VISA resource locks or semaphores at the application level
    may cure the problem even if the kernel mode driver is failing to
    protect access to the card like it should.
    Even if this fixes the problem PLEASE report it to NI so that they can
    fix it properly in the .sys file and let other users know that the
    workaround I suggested works.
    See:
    http://msdn.microsoft.com/library/default.asp?url=/library/en-us/network/hh/network/103ndisx_7mk2.asp
    Work-around Possibility #2: I don't know the details of setting up
    your DAQ card so if this question doesn't make any sense don't worry
    about it. Are you setting up the card with some empty array, zero
    memory size, or empty string value or something? I had this problem
    with a reflective memory card driver.
    Sometimes this can screw up a driver that isn't checking for this sort
    of thing with the result of it trying to reference a null ptr or
    something. Again, even if you fix the problem by error checking the
    values before you give them to the DAQ driver VI, make sure you tell
    NI about it.
    This explanation also jibes with what Microsoft has to say on
    IRQL_NOT_LESS_OR_EQUAL. See:
    http://msdn.microsoft.com/library/default.asp?url=/library/en-us/w2kmsgs/6077.asp
    3) There may be other explanations for your problem but these are two
    that I've run into personally. Try going to www.microsoft.com and
    doing a search on IRQL_NOT_LESS_OR_EQUAL if my two possibilities
    aren't the cause of your problem.
    4) Make sure you have the latest driver from NI for the NIDAQ. NI may
    have already fixed your problem in a later version of the NIDAQ
    driver.
    5) Also I would recommend making sure that you have the latest service
    pack (SP6A) installed or that you go ahead and upgrade to Win2000. As
    I recall when I had my one of my driver problems it was with an
    earlier SP release and upgrading SP's helped.
    6) If none of these suggestions help, you need to call NI help line
    (800-IEE-E488) and report this to see if they know about it so that
    they can give you a work around and see if they can recreate the
    problem and then fix it.

    I recently purchased Norton stuff and loaded it but dont know how to do all that stuff you said to do.
    okay.
    was that Norton Internet Security 2006? if so, right-click on the yellow ticky-Norton thing down in your task bar, and select "Norton Protection Center". click the LiveUpdate button. install everything it says is available at LiveUpdate. restart the PC if it asks you to.
    open Norton Protection Center again. click on "Norton AntiVirus". click on "Scans". click on "Run full system scan".
    once that's finished, and you've dealt to everything that shows up, do a spyware scan. if you don't have an antispyware program, download and install the free trial version of Ewido, and scan your PC with that.
    ewido anti-malware download
    once that's finished, and you've dealt to anything that shows up, go to the Symantec website (they make your Norton), and run one of their online virus scans. they take an eternity, so you may want to do that overnight:
    Symantec Security Check
    to do a disk cleanup, go "start > all programs > accessories > system tools > disk cleanup"
    to run chkdsk (that's a disk checking/repair utility in Windows), close all active programs, go into My Computer, right-click on your hard drive, select "properties", click on the "tools" tab, and click the "check now" button.
    to do a disk defrag, go "start > all programs > accessories > system tools > disk defragmenter"

  • Lately, I've been getting a blue screen in the midst of working and have to do a cold reboot to end it. Seems to happen when I'm closing windows or quitting applications. Not always, but sporadically. What causes this? I'm using 10.6.8 on early 2011 MBP.

    You have 10.6 on that machine, I suggest you stick with it for performance, third party hardware and software reasons as long as possible.
    Consider 10.8 (not 10.7) when it's released, because 10.7 and 10.8 will require a new investment in software and newer third party hardware as it requires newer drivers the old machines won't have. (forced upgrade because of software, really nice of them)

  • I'm getting "MACHINE_CHECK_EXCEPTION" blue screens

    But this is not the same as the other guys :/  
    this computer is about 3 months old and just started to get this error 2 days ago..."MACHINE_CHECK_EXCEPTION"  What the hell does that mean???
    I was started a game, went to the track to start racing and I was sitting at 2 frames per second.  For 3 months with this computer I've been getting avg of 100-140fps.  So i turn the game off, as soon as i turn it off i get a Blue screen then it rebooted!!!  It rebooted fine at that point.  I try another game UT2004, play for about 30 mins, shut off the game, BAM!!!! Blue screen again!!! I figure, "ok i need to reinstall xp".
    So i reinstall xp, I load the K8N Neo mobo drivers, reboot, works fine.  Install Audio Drivers, I get a blue screen "MACHINE_CHECK_EXCEPTION" on boot, I uninstall it, works fine.  I install SP1, blue screen"MACHINE_CHECK_EXCEPTION" on reboot, I uninstall and install SP2, works fine. Odd?  Yes, I think so.... Now I've tried all kinds of combos here between the BIOS and whats installed.  Most commonly ON board sound enabled, and the sound drivers NOT installed, i will not get a Blue screen...Most commonly.  Out of about 50 reboots to test this theory, when every i install the sound device's drivers i get the error.  So i'm thinking it has something to do with the drivers are conflicting with the hardware.  But, this same computer has been working fine for 3 months prior to 2 days ago.  I dont get it!!! Did my mobo go bad?  Is there anything out there that can fix this, something i need to look at.  I shouldn't have to use a sound card because the mobo's onboard sound is suppose to be fine.  Any help please!  
    Thanks

    interesting... machine_check_exception is a hardware related issue. typically caused with hardware and pentium processors, buti guess in your case its a little different. straighe from microsoft: "A machine check exception occurs when Windows XP and your hardware platform cannot recover from a hardware error so that the system can continue to run successfully and reliably. More specific diagnosis of machine check exceptions is difficult, and there is no general solution." You've got a beast of a computer there, so i really don't see why you'd be having much problem... i've heard overclocking is a common cause of this error, so if you are... change that. If that doesn't do it it could be your power supply, over heating, or bad memory. "
    I'm not overclocking, and he did menition "bad Memory"  So in moving that around I guess I'll have to try one stick at a time or both?

  • Ipad 2 is getting a blue screen of death

    Just a couple of days ago, my Ipad has started getting a blue screen of death. It gets a blue screen, and then shuts itself off. When it restarts, it's unresponsive for about 4-5 minutes before letting me using it again. When it lets me use it again, I have about 10 minutes before it starts all over. I'm hoping this is something that can be fixed whether hardware or software is the problem. I definitely don't want to have to spend $700 for the new iPad as good as it may be. I'm also serving in Manama, Bahrain for the next couple of years, and this island is no where near an Apple store.

    I would try to reset the iPad via iTunes, I don't think the problem is software based thou. I once had a mac mini which behaved simularly, the problem disapered when I changed the RAM, this isn't possible on the iPad thou.
    In the end, you probably have to do what Johnathan states.

  • I get a blue screen on Windows 7 startup via bootcamp (Lion OS)

    My Windows 7 works fine via VMWare Fusion, however since having upgrading to Lion:
    1. Get a blue screen hardware issue starting up directly in Windows which appears just after the Windows startup animation. Using the windows repair doesn't seem to do anything.
    2. Bootcamp now missing from the Mac OS 'Start up' target disk.
    Has anyone solved these problems?
    Infuriating that Apple have released Lion and it buggers up Bootcamp. I do not wish to go throught the process of partitioning and reinstalling Windows again as it takes days because I have to install Vista and wait a while for Windows to eventually install both service packs before I can then install the Windows 7 upgrade disk. It took approxiamtely 2 days of time to do this!!!
    Thank you.

    I can easily get into Windows. It is just that the drivers don't seem to work correct, and makes the screen dark.

  • I get the blue screen whenever I try to install the bootcamp drivers in windows 7

    I just recently installed windows 7 home on my 2011 imac useing bootcamp.
    Everything seemed to install fine however whenever I try to run the bootcamp drivers in windows to get my mouse and wifi and all that to work I get a blue screened.
    Any Ideas?
    Ive followed the exact instructions from the manual for OSX and nothing seems to work.

    Question: Does the Windows disk that you are using have SP2 (Service Pack 2)? In other words, is your version of Windows a FULL version (and not an upgrade version) of XPSP2 Home Edition?
    Having SP2 is a requirement to have XP installed on an intel Mac.
    If you already have the right version then I am not sure what exactly the issue may be.

  • Get the blue screen but the TV doesnt find the signal from my mac via hdmi

    Before my mac could connect to my TV Samsungs LE32B350 without any problem, but now it just keep saying no signal from the tv. I get a blue screen when I connect the hdmi on the laptop for one sec then nothing happens. I have tried search for more screens but aint finding anything.
    Please help me

    Unfortunately older G4 minis are very touchy about certain hi-res monitors when run from DVI. Hi-res in this case means any monitor whose resolution causes the pixel clock to be above 135 MHz. It is normally the case that 1680 x 1050 timing will have a pixel clock above 135 MHz, although there is no way to observe that directly from within OS X.
    There are only two known work-arounds for the issue. One is to run the monitor over a VGA interface. The other is to use a program like SwitchRes X to lower the pixel clock below 135 MHz. If you choose to do the latter, write back if you'd like some guidance on how to do that.
