BSOD on startup Vista crcdisk.sys

• Computer stops during startup, Vista crcdisk.sys

  When I try to turn on my computer, I get a screen saying that Windows is not shut down properly. It gives me the opportunity to launch startup repair or start windows normally. With option, I get the black screen with the green bar for maybe 3-4 seconds before my computer turn off suddenly. I tried to hit f8 and have advanced boot options. With one of the security modes selected, I see loading files. The last file I see is crcdisk.sys and then the computer shuts down. I thought maybe it was a start power supply problem but by replacing the power supply did not solve the problem.  I tried to boot from the disc of the operating system that came with the computer, after "loading windows files" it does the same thing and stop at the black screen with the green bar. I downloaded a Vista recovery disk and tried to boot from that, same result.

  Ideas/suggestions on how to solve this problem would be appreciated.

  Looks like you have a hardware problem - most likely with your hard drive, but perhaps also something else.  I recommend that take you to a repair shop of computer with a good reputation for the service (NOT Geek Squad or any company like that).  Or you can send it to the manufacturer for service (compare costs, benefits, schedule, availability of parts, effort, reliability, and anything else feel you is important and make a decision).  If you can, try to back up your data first, as it is likely the drive will be wiped clean in the process.

  You can use Knoppixhttp://www.knopper.net/knoppix/index-en.html with a good ISO as Copier: http://isorecorder.alexfeinman.com/isorecorder.htm as well as a blank CD (made on a different computer).  Boot this disk.  This should give you enough access to the system (if you do not have any other means) to backup your important data.  If this does not work, try to remove the hard drive and it enslavement to another computer and use this computer to access the drive and back up the data.

  I hope this helps.

  Good luck!

• Failure of Windows Vista and the SafeMode of startup failure - crcdisk.sys

  Hello

  I have a Dell Inspiron laptop computer 2 GB RAM. He had a few months now, and everything has been fine.

  Started a few days ago from freezing occasionally so I was forced to restart. CTRL + ALT + DELETE has refused to do anything and so I had to manually remove the battery.

  A frozen about three times and then once rebooted showed the BSOD saying something the system failure.

  So I rebooted once more and now it restarts just without going on the login screen. I tried to run in safe mode, but it gets stuck on crcdisk.sys or goes in an endless process to restart again.

  Is there anyway that I might be able to get back on without doing a full factory reset, as I have all my work stored on the hard drive integrated without backup.

  I can open the system recovery options, but none of these options seem to work. All my points of recovery have been removed.

  Startup Repair doesn't indicate a problem with the system, so I thought maybe it was a virus? The same thing happened to my wife a few days ago computer and that uses the same Wifi network as me.

  Jacob.

  To search for malicious software, you must do in Mode safe mode with networking, but you say that you can not get the Options.

  There is information below data recovery.

  And Startup Repair Info, too.

  Data recovery:

  1. slave of your hard drive in another computer and read/save your data out there.

  2. put your Hard drive in a USB hard drive case, plug it into another computer and read/save from there.

  3 Alternatively, use Knoppix Live CD to recover data:

  http://www.Knopper.NET/Knoppix/index-en.html

  Download/save the file Knoppix Live CD ISO above.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  http://isorecorder.alexfeinman.com/isorecorder.htm

  Download the Vista software from the link above.

  After installing above ISO burning software, right click on the Knoppix ISO file > copy the Image to a CD.

  Knoppix is not installed on your PC; use only the resources of your PC, RAM, graphics etc.

  Change the boot order in YOUR computer/laptop to the CD/DVD Drive 1^st in the boot order.

  Plug a Flash Drive/Memory Stick, BOOT with the Live CD, and you should be able to read the hard drive.

  When the desktop loads, you will see at least two drive hard icons on the desktop (one for your hard drive) and one for the USB key.

  Click on the icons of hard drive to open and to understand which drive is which.

  Click the icon for the USB drive and click on "Actions > Change the read/write mode" so you can write to disk (it is read-only by default for security reasons).

  Now to find the files you want to back up, just drag and drop them on the USB. When you're done, shut down the system and remove the USB key.

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  If Safe Mode does not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:

  Download the ISO on the link provided and make a record of repair time it starts.

  Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

  At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.

  When you have changed that, insert the Bootable disk you did in the drive and reboot.

It cannot be used to install or reinstall Windows Vista, and is just a Windows PE interface to recovering your PC.

• Error Vista crcdisk.sys Tecra A4 - solution

  Hello world!

  I have create this post to share my experience of installing vista on a Tecra A4 (tecra a4 257 to be precise)

  to be brief, the first time that the installation of vista freeze, it is on the famous "crcdisk.sys" in safe mode
  ---> solution: reboot on the installation DVD and go to "repair my computer" then the command prompt to delete/rename \windows\system32\drivers\pcmcia.sys and \windows\system32\driverstore\filerepository\pcmci ablablabla

  But even after that, I'm not able to complete the installation because I uncounter the famous 'black screen of death' (more precise, after the first restart, Setup will "finish installation" and after a while, the screen goes white and my laptop freeze without HDD activity more)
  ---> solution: after remove/rename pcmcia.sys e.a., delete/rename all the files on your Texas instruments PCIxx21 because it is this f * ing material that make vista freezing!

  so I renamed all the files in the windows\system32\drivers folder named * 1394 * (for firewire controller that belongs to a TI PCIxx21) as well as in the \windows\system32\driverstore\filerepository\ and \windows\inf\ folder
  I have renamed in the same files all files named sd * (for the reader of card memory, another part of TI PCIxx21)

  After that installation is finished and I was able to see vista and aero for the first time (sniff...)

  I hope that someone help :-)

  I think all information on Vista are very useful to us because it s a new OS and there are always a lot of questions.

• crcdisk.sys interruption during the startup of Vista Basic on an E-machine

  Backround:

  I worked on this machine for about a week.  I'm sure it's a softeware and not a problem with the hardware to 90%.  I ran Startup Repair and corrects a problem with startups rehearsal where the machine would be blocking and I had to cut the power to restart the machine.  (By the way, the disk image I created with my machine for system recovery XP works fine but ultimately that the machine always stops before leaving).

  I don't think that the file crcdisk.sys is the problem.  I think it's loading the driver after that, but I knew how to say that whoever is.  I didn't go to c:/windows/system32/drivers and all files replaced by files from the backup of the system part and once again had the same problem.  The next thing I plan to do is to replace the directory with that of another Vista machine, but I did not understand how to get the files from one computer to another.

  Also, while searching with the command prompt, I discovered a number of files and directories that are as of 01/01/2029 to 03/01/2029.  It seems that some of these files are used, but I can't say to what extent.  I would also like to know where they came from since I never changed the date on this machine.  This difference in date might be part of the problem.

  The machine is preinstalled and I have no starup disk.  I tried to create with my other Vista machine, but he does not like my records.  Depending on the machine, they should be DVD/R, which is what I have.  Can what I missed and if I manage to create discs I use it on this computer to format and reinstall?

  Thanks in advance for your answer.

• Windows Vista update: STOP 0x0000007b on crcdisk.sys

  I tried to apply the patches via Windows Update February, twice, twice completely streaked my Vista installation.

  What happens is that Windows Update downloads updates and application restart. The restart ends at STOP 0x0000007b.
  If I then boot in safe mode, I can see the boot process stop for about a minute with crcdisk.sys displayed, followed by the BSOD.
  The parameters are: STOP 0x0000007b (0x0c0000000e, 0 x 000000000, 0x080399bb0, 0 x 0000000).
  This happens both to the normal boot and safe, so the only solution I found was to reimage the computer.

  I have on my firewall on the computer 1, 2 anti-virus and 1 products anti-intrusion and surf using Firefox with several security extensions, so I guess that my computer is not infected.

  Ideas patch that is responsible for the problem and how to avoid it?

  However, I am not infected with rootkit Alureon, I have set my computer with Avast, Malwarebytes, McAfee and Spybot S & D scan.
  So I doubt rather requests above that Alureon is the sole cause of the BSOD.

  Rootkit TDSS [AKA Trojan W32/Alureon] has silently the net
  
  TDSS rootkit 3rd variant is the last member of the Tdss rootkit family that is spreading quickly all over the world. While a number of rootkits is just developed as a proof of concept, this is not the case. TDSS rootkit is well known corporate antivirus because of his goal to get full control over the infected computers and to use them as zombies for its botnet.

  During these years, that he has always shown a team of skilled people behind it, which always applied advanced techniques often able to bypass antirootkit software. In fact, this last Variant can be easily named as the stealth rootkit in the wild.

  This infection is having all the best of MBR rootkit, the best of the Rustock.C and the experience of the old Tdss variants. The result is an infection that spreads quickly on the net and it is not detected by almost all security software and 3rd party anti rootkit software. [emphasis]

  .. [20 Nov-09] terms no antirootkit is able to bypass disk filtering technical used by Tdss rootkit but, even if it were possible, this rootkit could not be detected by file size cross check because the size of infected files and original file are exactly the same.

• Vista hangs at crcdisk.sys

  Hello

  Another machine with a typical problem. My laptop Sony VGN-SZ290 primer not. When I do a boot to the top in safe mode, it hangs at crcdisk.sys. None of the other startup options not work either. I could do a memory scan and it came back clean. When it does not start, I have two options: 1) start Windows normally and repair Windows Run) 2. Neither one of those who will do anything, all I get is a white screen. In addition, like many people, I don't have a recovery disk. You would think that after paying $1,500, Sony could afford to spring for a $1 plastic coin, oh well. From what I see online, this is a common problem. Unfortuantely none of these solutions worked for me.

  Any help will be greatly appreciated.

  Yes, you will still be able to use your product key.

  Yes, sony should be able to get a replacement hard drive. It would be covered by any warranty.

  Thank you!

• Why Vista stuck on crcdisk.sys on my pc tailor-made with a new HARD drive?

  Hello, forums:

  Okay, so I have problems with a full installation of Windows Vista (x 32).  I get the mode safe mode crcdisk.sys freeze with.  Normal mode is just stuck on a loading green bar slooow.

  Now, I've read countless sites on this issue, but nothing seemed to work.  All those who have problems had a pre-built system, or has been updated to XP.  I don't have that a facility tailor-made with nothing else on.  I know that said first thing would be to delete the c:\windows\system32\drivers\sptd.sys and pcmcia.sys, but I tried this several times and nothing starts later.

  Here are the specs of my machine:

  Motherboard Gigabyte H67M-D2-B3
  2 x 2 GB of ram (I removed a stick for installation)
  Intel i5 processor

  I do not use a wireless card on this pc, ethernet only.

  In addition, nothing based on USB are connected at present.

• T410 nvlddmkm.sys BSOD on startup

  Hi all

  I had my T410 since the end of last month and had a BSOD on startup several times so far. Whenever I caught, I noticed that the driver nvlddmkm.sys nvidia was the cause. Each time the BSOD, I get the prompt "windows did not start successfully", how by selecting "Start windows normally" translates the fine start System. Since this BSOD is only presented to a cold start, I'm not too hampered by it outside my boot up times by doubling the time it does. I ran the update of the bios/driver Thinkvantage, as well as I'm running with the latest updates for Win7 Pro x 64.

  Everyone knows this? If so, have you found a solution? No matter what Lenovo personal support out there have an entry?

  Thank you
