Stability issues, random hangs (black or white screen), some dmp files

I've been experiencing some significant stability issues with my PC for a couple of months now. The problems often don't result in BSODs (maybe once or twice?) but rather things like:

• The screen(s) flash and then go full white and the system becomes unresponsive (no response to keyboard, mouse, caps lock doesn't respond, won't respond to pings from other systems, etc.)
• I'll return to my desk and find the screens black and the system unresponsive
• I'll return to my desk and find the system has rebooted, with nothing more than a note in Event Viewer that the previous shutdown was unexpected or that the system recovered from a bugcheck.

The latter symptom at least produces dmp files, so I'm hoping that while it doesn't come specifically from a BSOD with a stop code, maybe the dmp files and other info will give someone enough to go on to point me in the right direction.

(Note: you'll see a handful of (repeating) error messages from the event viewer related to my active directory - I'm running Samba4 and have an ACL problem on the GPO storage location that I'm working on every now and then, but all I really care about is the authentication it provides which works fine - my working assumption is AD issues aren't the cause of this.)

Thanks for your time and any assistance anyone can provide!

Hello shill and welcome to the TenForums :)

The crash dump files are pointing to a graphics driver problem.

Code:

fffff800`38602610  fffff80f`ff794680Unable to load image nvlddmkm.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for nvlddmkm.sys
*** ERROR: Module load completed but symbols could not be loaded for nvlddmkm.sys
 nvlddmkm+0x814680

Please update the NVidia driver. The best way to do this is to uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from your Graphics card manufacturer or from the NVidia website. When you do this be sure the "clean install" box is checked and only install the Graphics driver and the PhysX driver.

There were also two other drivers that were listed as not loading correctly:

Code:

fffff800`386021c8  fffff80f`fd6d3186Unable to load image VBoxNetLwf.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for VBoxNetLwf.sys
*** ERROR: Module load completed but symbols could not be loaded for VBoxNetLwf.sys
 VBoxNetLwf+0x3186

fffff800`38601728  fffff80f`fee784edUnable to load image e1i63x64.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for e1i63x64.sys
*** ERROR: Module load completed but symbols could not be loaded for e1i63x64.sys
 e1i63x64+0x184ed

These refer to the VirtualBox drivers and the Intel Gigabit Adapter Drivers. Please also look for newer versions of these drivers or try re-installing them.

I've been suspecting the video card but the drivers were nearly current so I was afraid it might be hardware related. I've removed and re-added the Nvidia and Intel drivers - will see how much things fare.

Thanks for your help!
