Windows 7: BSOD, various ntoskrnl.exe errors possible OpenVPN related issue

05 Jul 2012   #1

Windows 7 Home Premium SP1 x64
BSOD, various ntoskrnl.exe errors possible OpenVPN related issue

1 Month Old Samsung Series 3 Notebook
Windows Home Premium x64 OEM
See CPUID screen shots for details.

Had no problems for the first 3 weeks and then all of a sudden mega BSOD issues. I'm getting errors just surfing the net with computer under minimum load. It was great the first few weeks, now it is unusable. The only possible change I remember performing prior to the errors was installing OpenVPN and then uninstalling it as I was unable to get it to work with uTorrent but this may be unrelated. I have tried troubleshooting by doing the following to no avail:

1. Restore Windows to prior place.
2. Reinstalled Windows
3. Ran memtestx86
4. Ran all tests on Seatools for Hardrive errors.

Any advice would be much appreciated,

Also, thank you very much in advance, you guys rock!

Were you aware of the above? If so, please explain your troubleshooting steps.

Your crashes primarily indicate hard disk problems. This could mean hard disk corruption, bad sectors, a failing hard disk, Windows files or registry corruption, viruses, or memory problems. It appears you have done most of the troubleshooting steps I normally recommend, but make sure you do at least 7-10 passes of Memtest86+.

    For any drives that do not give the message:
    Windows has checked the file system and found no problems
    run disk check again as above. In other words, if it says:
    Windows has made corrections to the file system
    after running the disk check, run the disk check again.

  • Run all Basic tests with SeaTools: S.M.A.R.T. Check, Short Drive Self Test, Drive Information, Short Generic, and Long Generic. Run the tests for all HDDs.
    SeaTools for Windows

    SeaTools for DOS
  • If you have an SSD, make sure the following are up to date:
    • SSD firmware
    • BIOS Version
    • Chipset Drivers
    • Hard disk controller drivers/SATA drivers
    • If you have a Marvell IDE ATA/ATAPI device, make sure the drivers are up to date from the Intel site or Marvell site and not from your motherboard/vendor support site.

  • Check Windows for corruption. Run SFC /SCANNOW Command - System File Checker up to three times to fix all errors with a restart in between each. Post back if it continues to show errors after a fourth run or if the first run comes back with no integrity violations. Use OPTION THREE of SFC /SCANNOW Command - System File Checker to provide us with the sfcdetails.txt file if errors occur.

  • Download and install Malwarebytes, update it, do not start the free trial, and then run a full scan. Also run a full scan with your antivirus software installed on your system. If you do not have antivirus software installed, see the Good and Free system security combination. for better security steps and scanning tools. Make sure to update the security software before running the full scan.

  • Run the boot version of Memtest86+ paying close attention to Parts 2 and 3 of the tutorial. Also, in case Memtest86+ misses anything and comes up with no errors, run the extended version of the Windows Memory Diagnostics Tool for at least five passes. These you may want to run overnight since they take a long time to complete (run them an hour before bed each of the next two nights and check before going to sleep that they are still running).
    warning   Warning
    Before you proceed with the following, answer these two questions: Are you still under warranty? Does your warranty allow you to open up the machine to check hardware? If you are unsure of the answers to these questions, contact your system manufacturer. WARNING: The steps that follow can void your warranty!!!

    For Part 3: If You Have Errors: If you swap any memory components, follow these steps for ESD safety:
    1. Shut down and turn off your computer.
    2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
    3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
    4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working. If you do not have an anti-static workbench, desk, or pad, you can use your computer tower/case by finding a metal hold in it, such as a drive bay.
    Once these steps have been followed, it is safe to remove and replace components within your computer.

Hard Disk Connection Check:
Since this is a laptop, also check the hard disk connection:
The first thing to check is whether the hard disk is physically connected to the motherboard properly. To do so:
  • Shut down and turn off the computer
  • Remove the AC Adapter
  • Remove the battery
  • Hold down the power button for 15-30 seconds to close the circuit and drain any residual power
  • Remove the panel on the underside of the laptop where the hard disk is housed
  • Remove and re-insert the hard disk by sliding it away from the connector and then gently but firmly pressing it back into the connector (no screws should need to be removed to do this step)
  • Replace the panel on the underside of the laptop to cover the hard disk
  • Replace the battery
  • Replace the AC Adapter
  • Turn on the computer and see how it responds
Post back once these steps have been implemented whether the system is stable. Sometimes these crashes can occur due to a loose connection.

So I ran all tests above but still got no errors.

I didn't open up case to check HDD connection as I did not want to void warranty.

Still getting BSOD, slow performance even after another fresh windows install.

Interestingly after the latest BSOD the hard drive was not detectable in the BIOS following the restart? After another restart it came back and booted into Windows.

Could the HDD be failing but still passing chkdsk and seatools?

Either way, I'm almost sure some hardware is in need of a replacement and will be booking it in for a warranty repair unless you guys have a better idea?

If you are still having problems after a fresh install, and you do not want to open anything up for fear of voiding the warranty, I would suggest that you use the warranty. You paid for it, so you really should take advantage of it while you can. Let us know what they find. :)

Just got it back from the samsung warranty repair place after it being there for 7 days. They replaced the HDD thinking it was stuffed. Came here to give an update of what the problem was as requested.

Within 10 min of use I get another BSOD. WTF! You think they could check it before handing it back. So pissed off with Samsung. I obviously have a dud so they least they could do is replace it.

Oh well, back to the store she goes!
