• nvlddmkm.sys error

  I've had Windows Vista for about 2 weeks now, and I've done 4 fees installs try different confgurations for this error to the LESS to a minimum. When I use the operating system 3d treatment, I get the error...

  "Display driver nvlddmkm.sys has stopped responding and has recovered."

  This seems to be a plague of Vista users, on searching the net for an answer as to why, it seems to happen for all versions of Vista both 32 and 64-bit. Happeneing for people using different video card, ATI and nVIDIA chips. NVIDIA users get nvlddmkm.sys error and ATI users get the error atikmdag.sys.

  This error most commonly appens when I'm a game or using a 3D or graphics program such as GIMP and the Blender and rarely when just using the Explorer. The program that I use currently hangs, and I use the "Task Manager" to stop the programme concerned. If I reboot the system, I get this error whenever I'm trying to use the same or similar program. After the reboot, it is just a matter or an hour, it seems, before that happens again.

  For me personally this has happened using 3 chipsets of different motherboard and 3 different video cards. Same scenario is becoming very frusterating. Someone has ideas News on how to stop this?

  Hi V3X,

  Please use the forum for Support of Vista,

  Unfortunately, it is a known problem that occurred in Vista and Nvidia or Ati driver as you said.  It is not a fix for this yet.  There are a few works about depend on the hardware you have.  If you communicate with Nvidia, they will be able to tell you exactly what to do to work around this problem.

  Sorry again.

  Shortly after this awful blue screen appears with the error "atikmpag.sys."

  Thank you all! Alex.

  Hello

  The error message indicates a problem with the chip of the graphics card or graphics card driver.
  BSOD may occur if the graphic temperature would be too high, it might lead to chart falls down and BSOD.

  I think you should follow the advice of s Ilay and should reinstall or update the graphics driver.
  The old driver must be removed before you begin the new installation.
  In case this does not improve the functionality, I recommend you to perform a complete system recovery.

  Hope that this would finally solve the problems.

  Do not install an operating system is usually caused by (in order of probability):

  1. you are trying to install with other devices connected to the computer. Unplug them before trying to make an installation.

  2. "" "" defective installation media. "" Check the CD/DVD installation for scratches, tasks. Try another machine.

  3. bad optical drive. Test with another CD/DVD bootable or Exchange for a well-known work.

  4. faulty RAM. Test with Memtest86 + www.memtest.org . You will download the .iso image file to create a bootable cd. Burn the file with the third party burning software *-as an image, not in the form of data. Then start with the media that you did (you may need to change the boot priority in your BIOS so that the optical drive is the first boot device). The test runs immediately. The test run for an hour or two--at least that errors are seen immediately. If you get any errors, replace the RAM.

  * It is not necessary to have a third party burning software in Windows 7 since Win7 natively allows to burn an .iso. Other operating systems require it. A good free choice ImgBurn comes from www.imgburn.com .

  5. bad hard drive. Test with a diagnostic utility downloaded from site of the disc mftr... You create a bootable CD with the files you download. Burn the file with a third-party burning software (unless you have Windows 7, that allows to record the .isos natively) - as an image, not in the form of data. Boot with the CD that you have done and do a full test of the reader. The physical tests fail, replace it.

• BSOD, c:\windows\system32\drivers\mrxdav.sys error?

  I am a veterinary technician, not a computer tech, so I'm out of my depth on this and need help, because these computers are essential for the work I do.

  I work with two laptops, Dell Latitude D600 (I know, I know - they're old.) New ones have been approved as soon as budget free of the order).  Specifications are the following:

  1.60 Ghz processor; 27 GB hard drive; 599 Mhz, 256 MB of RAM, running Windows XP Pro w/Service Pk 3

  We use one of the cell phones as our main unit and the other is our backup.  About 3 weeks, our main unit suddenly came with the BSOD on boot-up top, with the following error message:

  C:\windows\system32\drivers\mrxdav.sys

  The driver unloaded without cancelling pending operations.

  We had not added anything to the extent of the software or hardware is concerned and had not changed anything except for the addition of new text files through an application that we run.  A opted for our backup laptop and who ran very well for the last few weeks, but now we get the same BSOD and error on this unit as well.  I was able to get the machine backup at startup and function normally after about 100 restarts the other day, and he ran all day with no problems once that it loaded everything.

  How do we get this straightened out? We do not have a computer scientist - just a couple of people who know a little more to turn on a computer/turn off.  I ran a clean-up/management application (I-Obit AdvancedCare) for cleaning the registry errors, etc., but that has not solved the problem.

  The error message indicates an infection, but because you have scanned, it is more likely that the portable master knows hardware problems and/or the operating system is corrupt. If you are Imaging for the second laptop, that explains why you see the same questions about this. Best free now part of budget money.

  Start with the RAM and then make the hard drive.

  If good test material, back up your data if necessary and do a clean install of Windows.

• Vista fails to start on mv61xx.sys, error 0xc0000221

  My system suddenly no longer starts. The good news is: I managed to fix it and put the solution below, so that anyone can benefit from. The bad news is that the Vista recovery has some (at least for me) unexplained oddities that I'd like to get an answer to. So, lets describe.

  Symptom:

  -The PC stops in the process of starting with a critical failure. Fault that it displays "mv61xx.sys" says it also displays 0xc0000221 error code

  -mv61xx.sys is related to a driver SATA/IDE of Marvel. The error code is related to a Windows driver cannot load, is not present or because it is corrupt.

  Solution:

  -Reset CMOS on the motherboard (Asus P5Q) using the CMOS jumper, remove the CMOS battery and remove the power cord to reset.

  Remarks: (follow the questions below):

  -Note that the solution is nowhere about the problem that Vista has reported. Vista has indicated that it cannot load a driver for some, because it is missing or damaged.

  -Recovery of starting Windows (via the installation DVD) has not solved the problem.  It indicates the fault 0xc0000221 code (probably found it in a log file) and suggests using a previous system restore point to cure the problem. Has done this, but the problem had not gone away.

  -Then, I decided to use the recovery console. The "sfc/scannow" command did not complete, it gave an error. I googled the problem and found that this error can be bypassed by giving sfc additional parameters: "sfc/SCANNOW damaged = C: \ /OFFWINDIR =" C:\WINDOWS "

  -sfc reported no problem. So it's weird: boot Vista reports that a driver file is missing or damaged, but sfc has no problem

  - As an experiment, in the recovery console, I've renamed the driver mv61xx.sys (in C:\windows\system32\drivers) in mv61xx.bak. I restarted my PC. The behavior is different: this time the 0xc0000221 error does not appear, it just went to a black screen. Which makes me think that Vista was previously able to load the driver for mv61xx.sys, otherwise the error reported would be the same.

  -Then I started from DVD, check if sfc was able to detect that I deleted the driver mv61xx.sys (renaming). I ran sfc and... sfc reported no problems, nothing has been repaired.

  So my questions boil up to:

  -Why Vista report a problem with a corrupted driver or missing mv61xx.sys while the symptoms above strongly suggest that the problem lies elsewhere

  -Why the SFC command in recovery console does not repair the mv61xx.sys driver that I have renamed in mv61xx.bak.

  Thank you. Roland.

  (for the answer to the problem, please see the first post in this thread)

  Hi Lorien,

  first of all, thank you for your quick response. BTW, I was unable to boot from the HARD drive when 0xc0000221 error, I found myself stuck in the middle of the boot process, in a black screen with white characters. The only way I could try the recovery was starting from my Vista installation DVD.

  I don't think that the cause of the problem was a missing or corrupted driver (which was what Windows has reported with error 0xc0000221). I think that I could solve the problem by resetting my CMOS. The problem is now completely gone, even on several boots.

  Now with my PC to the top and runs again, I went into the device by your advice Manager. I see only one exclamation point in there that seems to be independent: an adapter (Microsoft ISATAP, probably a virtual network adapter) has a problem loading.  The node relevant in ("Marvell 61xx controller RAID') Device Manager, when you double click it, shows status"this device works properly.". The driver version is 1.2.0.57, it has been WHQL' ed.

  I also studied the event viewer on your suggestion. I don't see any entry with this error 0xc0000221. Which is probably logical: because Windows cannot gain access to this driver, it has limited access to the disk (because the driver is associated with disk: it is a RAID controller), so Windows cannot save the error on the disc.

  So, overall, with my post I have three objectives:

  -Raise awareness of other users a possible fix if they encounter the same problem as me

  -(optionally) to improve the quality of the SFC utility

  -(possibly) improve feedback that Windows gives to the user at boot fails

  -Improve my understanding of the recovery process

  So, back to the SFC. You noted that SFC checks all system files, just a subset. But I expect that the system files that are considered "critical" for Windows are in this subset. However, with mv61xx.sys, this doesn't seem to be the case: Windows reported at the start that he couldn't continue the start because this file is critical for the system, but CFS seem to have another opinion. Could not check if mv61xx.sys is really not in the list of files that SFC analysis?

  Secondly, is it possible that the mv61xx.sys pilot bails out with a 0xc0000221 error code, and Windows boot wrong is reported as a type of "load driver" of the problem, so that everything else goes wrong?

  I looked into your profile and noticed that you do not work for Microsoft. So if you can not answer my questions, I can understand that, since there are rather thorough type of questions, so I guess that only someone from Microsoft can answer those. In this case, would you happen to have a suggestion for a person or a contact forum?

  Thank you

  Roland.
