New System Windows 8.1 Unexpected Kernel Mode Trap

My System:
Asrock h87 Performance
Intel I5 4570
XFX DD 280x
G Skill 2x 4g PC3 1700
Samsung 840 Evo 120gb
3 HDDs
Superflower 650w Golden King
Antec Eleven Hundred Case

My problem:
Sometimes when browsing, and when I try to download games from Steam I get Unexpected_Kernel_Mode_Trap blue screens. The most common crash is from Ndu.sys, but have also had from netio.sys; volsnap.sys; and wanarp.sys.

What I have done:
Memtest 86; did seven passes with no errors. Scan Disk on the the two HDDs that Steam uses with no errors. Reinstalled motherboard drivers, intel drivers, and my Lan driver (also from intel). Really confused as to what's up. Not sure how/what to check next.

Any help would be greatly appreciated.

  1. I think I solved it on my own.

    The problem was Asrock Xfast LAN utility and/or my seagate 1tb HDD starting to die. The two of them together produced the errors. After I deleted the utility I no longer had crashes, but started to get hard disk failure messages. Xfast LAN might have also been installed on the drive that is dying as well.
  2. How Can I Fix the UNEXPECTED_KERNEL_MODE_TRAP Windows 8 Error?

    UNEXPECTED_KERNEL_MODE_TRAP is displayed in the Blue Screen of Death (BSOD). The error is mostly generated due to hardware failure or because of installation of inappropriate or incompatible device drivers. As with other Blue Screen of Death errors, a simple restart may resolve the issue. However if the problem persists, the computer must be restarted in safe mode and any newly installed device driver must be uninstalled to make Windows 8.1(different Windows8) computer run smoothly.

    1. Restart the Windows 8.1 computer.
    2. As the system restarts, press Shift+F8 key continuously to display the Advanced Boot Options screen.
    3. On the Advanced Boot Options screen, make sure that Safe Mode is selected and press Enter to start Windows 8.1 computer in safe mode.

    4. Log on to Windows 8.1 computer with the administrator account.
    5. Click Desktop tile from the Start screen to go to the desktop screen.
    6. Once on the desktop screen, hover mouse to the bottom right corner of the window.
    7. From the displayed options, click Settings.
    8. On the Settings pane, click Control Panel.
    9. On the opened All Control Panel Items window, click Device Manager.
    10. On Device Manager window, expand the category of the problematic device.
    11. Once expanded, right-click the device driver that is to be uninstalled.
    12. From the context menu that appears, click Uninstall to remove the selected driver.
    13. On Confirm Device Uninstall box, click OK to confirm the uninstallation of problematic device driver.
    14. Wait till the selected driver is uninstalled and restart the Windows 8.1 computer normally if required. driver for samsung HDD refer to Samsung site and download driver for Windows 8.1.
    16.Dowload driver for LAN refer to Asrock(see on your Motherboard for model and reversion) site and finally installing drivers.
  3. A common cause of this is hardware on the way out, namely hdds. However, having been plagued by this for quite some time I found it was the simplest solution - those who have modular power supplies, check the connections are seated properly at both ends. If you still have the problem, consider swapping out the PSU or using a different power outlet, as surges can also cause this and weaken the PSU.
