I've been having this problem on my custom built computer since this morning. This started when I received advice from ASRock tech support to reset my UEFI settings to default to fix an unrelated problem. I did that, and ever since then, my computer's stability has plummeted.
 

  • OS - Windows 7 Professional
  • Architecture - x64
  • What was the original OS? - There was none, this is a custom built.
  • OEM or retail? - Technically retail but it says OEM on the box.
  • Age of hardware - A week as of today
  • Age of OS - Reinstalled as of today
  • CPU - AMD FX-8350 (Not overclocked)
  • GPU - EVGA Geforce GTX 950 (/w DVI to VGA adapter)
  • Motherboard - ASRock Fatal1ty 970 Performance
  • Power Supply - EVGA 500 Watt
  • Manufacturer and model number - N/A, custom built
  • Laptop/Desktop - Desktop

The system isn't stable enough to run Sysnative BSOD Dump in normal mode in its entirety. The system blue screened during the "Waiting for tasks to complete" phase. Attached is the zipped up incomplete dump as well as a fresh one taken during safe mode (/w networking).

 

I've tried updating drivers, uninstalling and reinstalling video drivers, disabling video drivers, reinstalling Windows, and messing with UEFI settings.

 

Memtest86 shows 0 errors. Video Memory stress Test (VMT.exe) shows many errors when doing a full scan. The odd thing is that it's not reliable. Sometimes it shows errors, sometimes it triggers a blue screen, sometimes it completes with nothing wrong. OCCT's gpu memtest feature, however, consistently shows 0 errors.

 

The only thing that seems to make the computer any sort of stable is putting it in safe mode. I'd try taking out the video card, but my motherboard doesn't have on board graphics.

Only 4 Windows Update hotfixes installed.  Most systems with SP1 have 350-500 or more.  Please visit Windows Update and get ALL available updates (it may take several trips to get them all).
The actual number is not important.  Rather it's important that you checked manually, installed any available updates, and didn't experience any errors when checking or updating.

These devices have problems in Device Manager:

 

Universal Serial Bus (USB) Controller    PCI\VEN_1B6F&DEV_7052&SUBSYS_70521849&REV_00\4&11E7F7E8&0&0048    The drivers for this device are not installed.
Security Processor Loader Driver    ROOT\LEGACY_SPLDR\0000    This device is not present, is not working properly, or does not have all its drivers installed.
NVIDIA GeForce GTX 950    PCI\VEN_10DE&DEV_1402&SUBSYS_29583842&REV_A1\4&58C01F3&0&0018    This device is disabled.
Universal Serial Bus (USB) Controller    PCI\VEN_1B21&DEV_1142&SUBSYS_11421849&REV_00\4&3227B39C&0&0050    The drivers for this device are not installed.

The USB controllers are for your Etron USB 3.0 Extensible Host Controller - get the drivers from the AsRock support website for your motherboard

The Security Processor Loader Driver will be updated when you get ALL of your Windows Updates

The nVidia GTX 950 has been disabled.  Please enable it (maybe after all the other updates) and then update it's drivers to the latest, W7 compatible version

 

Once all of the above is fixed, if the video card still gives problems, please post another set of reports (that way we can see what's still in them that needs fixing)>

The computer is not remotely stable in normal mode. I started this topic in safe mode (/w networking). I opened msconfig and switched it to diagnostic startup and manually enabled the following services.

 

Spoiler

 

Basically, every service that was running in safe mode /w networking, plus Windows Update, Windows Audio, and their dependencies. Now that I did that, I'm checking for updates, which may take some time (I've never had good experiences with Windows Update).

Nope, blue screened again. I can't get through checking for updates without the computer crashing. Safe mode is the only reliable thing right now.

After trying a few things (namely chkdsk, which failed, verifier, and uninstalling a few drivers that were included in a disk with my motherboard) the computer is completely unstable in normal mode. It won't last a few minutes without a blue screen with the message "modification to system code or critical structure". Safe mode is once again the only reliable thing right now.

So this is interesting. I've installed Linux (without disturbing Windows. I just wanted this computer to be usable for the time being) and everything seems fine. I've installed Nvidia drivers, ran harsh graphics tests, and just generally used it, and there have been no errors or problems. I honestly don't understand what's going on. Perhaps it's a driver issue on Windows? Would reinstalling help?

First, run these free, bootable hardware diagnostics:  http://www.carrona.org/initdiag.html

Then run the rest of the diagnostics here (in Safe Mode if you must):  http://www.carrona.org/hwdiag.html

 

If they all pass, then do these steps in order until you meet with success:

 

 

here's some recovery/restore options (in this order):
 

 

- System Restore to a point before this started happening.

- DISM/SFC repair (DISM doesn't work with W7 although SFC.EXE does)
    

 

Then please run the following DISM commands to see if there's any problems with the system (from an elevated (Run as administrator) Command Prompt).  Press Enter after each one:
   
Dism /Online /Cleanup-Image /ScanHealth
   
Dism /Online /Cleanup-Image /CheckHealth
   
Dism /Online /Cleanup-Image /RestoreHealth
    FYI - I have repaired systems using the last command even though problems weren't found with the first 2 - so I suggest running them all.

    From this article: http://technet.microsoft.com/en-us/library/hh824869.aspx

    You can also run sfc.exe /scannow from an elevated (Run as administrator) Command Prompt to check for further corruption.


- RESET using the "Keep My Files" option (W8 calls this a REFRESH; W7 and earlier doesn't have this function)

- Repair install of the OS (Thanks to FreeBooter!):

    https://www.winhelp.us/non-destructive-reinstall-of-windows-xp.html


- RESET using the "Remove Everything" option (W8 calls this a RESET; W7 and earlier doesn't have this function)

If using W7 or earlier, this can be accomplished by resetting the system by use of the recovery partition/recovery disks/recovery drive.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

- Wipe and reinstall from the Recovery Partition (if so equipped)

- Wipe and reinstall from Recovery Media - to include deleting all partitions.
If you don't have them, you can usually order them from the OEM manufacturer of your system ( US points of contact here:  http://www.carrona.org/recdisc.html )

Memtest86 and Segate's disk checking tool found no errors. Prime95 ran for quite some time without any errors. I can't run anything from normal (not safe) mode for any extended period of time, so the rest of these tests are from past (but recent) experience. Furmark and Heaven benchmark both ran smoothly and without artifacts. Video Memory stress Test found thousands of errors, but I'm not sure how reliable this is, since OCCT's gpu memtest feature consistently found 0 errors. Furthermore, from linux, memtestCL also consistently finds 0 errors when testing 1800mb of video memory.

 

System restore isn't working properly. It either errors saying the restore point is corrupt, or the computer blue screens (when running in normal mode).

 

sfc.exe /scannow found no problems.

 

All three DISM commands failed with errors along the lines of "The restorehealth option is not recognized in this context."

 

Doing repair installs of Windows 7 doesn't work for me, because it requires running it in normal mode.

 

I don't have a recovery partition.

 

I'm now going to try reinstalling using the original installation disk. I'll post an update when this is done and critical drivers are installed. (Namely, nvidia's video card driver and an ethernet driver)

Again a blue screen. I installed the realtek LAN driver that came with my motherboard, installed Google Chrome, and I was in the process of installing Nvidia drivers. I had a few "Aw, Snap" errors from Chrome, then while watching a Youtube video (with Nvidia installing in the background) I got a Memory Management blue screen error.

Taking it slower, installing the driver without anything else running (as I probably should have from the beginning) it seems to be more stable. I'll update when/if there's another crash. I'll run a few stress tests as well.

MemtestCL shows no errors, memtestG80, however, shows many errors. It doesn't trigger a system crash, it just shows errors. I downloaded the Heaven 3.0 benchmark, and it was running smoothly with no visible artifacts, but when it was almost done, the system crashed with a "Page Fault In Non Paged Area" error. Though I'd like to point out, it is orders of magnitude more stable now.
 
Edit: I installed the Visual C++ 2010 runtime (x86) for Heaven 4.0 and ran a test with it on basic settings. I saw no artifacts during the benchmark, the graphics card didn't get above 69c, and it completed successfully without a system crash. I honestly don't know what's going on at this point, or if the memtestG80 results are relevant.
 
Edit 2: Now this is interesting. I ran Heaven 4.0 on extreme settings (utilizing DirectX 11 instead of DirectX 9) and there were a LOT of artifacts, as well as eventually a "Page Fault In Non Paged Area" blue screen.
 
Edit 3: Updating DirectX helped that problem. There aren't any more artifacts when running Heaven in DirectX 11 mode. I'm still concerned about the system's stability though. Chrome still gets "Aw, Snap" errors more often than normal. MemtestG80 still shows errors.
 
Final error count after 50 iterations over 128 MiB of GPU memory: 64510 errors
 
Where as memtestCL shows 0 errors.

Edit 4: Stability is still definitely a problem. It blue screened with the same error yet again during normal use.

After some experimentation, I think I've found two broken RAM sticks. I removed them and now it's stable (so far, total uptime of about 3 and a half hours under normal load without a blue screen). I plan on replacing the RAM sticks I removed and I will update if anything new happens. Until then, thanks for your help! It's odd though how it didn't show up in memtest86.

Sometimes (at work) we'll run MemTest86+ and will get no errors

Then we'll run Prime95's Blend test and weill get errors (this tests the RAM also).

As such, I suspect that neither test is a 100% reliable test.

FWIW - I was going to suggest another video card - but may have to reconsider my advice about MemTest/Prime95

Maybe add a "stick swap" section to the testing protocol for memory here:  http://www.carrona.org/memdiag.html

 

Good luck!  Please let us know how things work out.

I've never considered using Prime95 for anything other than CPU testing. Good advice, thank you! The steps on your website is basically what I did to find the two dead ram sticks. I've since gotten replacements for them and everything seems to be going smoothly. Haven't had any blue screens yet. A few Chrome crashes still but nothing entirely out of the ordinary. I've ran several stress tests for virtually every component now and it all seems stable. It seems those video memory tests (Video Memory stress Test and memtestg80 in particular) are not reliable. I had a friend with a stable computer run memtestg80 and he got the same errors I did.

 

Thanks again. And if I may ask, why is Windows' built in memory diagnostics not recommended?

I don't suggest it because I had problems with it not testing all of the RAM back when it first came out.

I switched to MemTest86/86+ at that time and haven't relooked at the test since then.

 

In short, the memory test itself occupies a part of the memory in order to run.

You can't test that because it would wipe the program out of memory.

There's another program (that runs inside of Windows) that does the same thing - so I don't suggest it either.
