Windows 7: Random BSODs since August MS patches

Random BSODs since August MS patches


up front, thank you for any help with this issue. I originally did not plan to create a post, hoping to solve the problem with information available on this forum, but after many days of trying and failing, I realized I am unable to resolve it without outside help.

PROBLEM 1 - PC is getting BSODs at random since August (possibly due to MS patches). = RESOLVED

The BSODs (incosistent and appearing at random) started from (approximately) the middle of August. Before then I experienced on average less than 1 BSOD per month. Based on information I found online this might have been a result of a faulty MS patch, MS14-045 (KB2982791).
The following temporary fix seemed to have solved the issue of BSODs (until last week that is):
1) Deleted fontcache C:\Windows\System32\FNTCACHE.DAT
2) Uninstalled Update KB2982791
3) Cleared C:\Windows\SoftwareDistribution
Sample list of BSODs:
STOP 0x0000001E
STOP 0x0000003B dxgmms1.sys
STOP 0x0000007E wdf01000.sys
PROBLEM 2 - Windows is not creating dump files. = RESOLVED

My last dmp file is from July. I did not do change anything since then but it seems that the system stopped generating dmp files around the time the August BSODs started.
I followed the instructions here and still nothing. I tried both options 1 (through Advanced System settings) and 3 (through cmd).

Virtual memory:
I tried different pagefile.sys settings; system managed size and custom size larger than installed RAM. Pagefile.sys currently at 16.6GB.
Windows Error Reporting Service is turned on and at Automatic.
Windows Management Instrumentation is Started and Automatic.

PROBLEM 3 - SFC /scannow not working.

I tried it in Win7 cmd, Safe Mode and in System Recovery:
1) Win7: it instantaneously (i.e. it did not even run) gave the following message:
"Beginning system scan. This process will take some time.
Beginning verification phase of system scan.
Verification 0% complete.
Windows Resource Protection did not find any integrity violations."
2) Safe Mode: The same message as in 1) appeared.

3) System recovery via boot+F8: SFC /scannow /offwindir=c:\windows /offbootdir=c:\ gave a slightly different message this time:
"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again"
Regardless of restarts, the message is always the same. According to some, this is because of C:\Windows\WinSxS\pending.xml.01ca7... and reboot.xml. I tried renaming/removing the pending.xml through cmd but it did not work. According to this post it is best to leave it alone, so I did.
PROBLEM 4 - Windows Update not working properly.

Since the August update issue, I turned updates to manual download and install. Strangely, some downloads don't work, giving me a 80073712 error code, while others do.

Attempted BSOD resolutions:

Memory: Both Memtest68+ and Windows Memory Diagnostic.
GPU: Stress test in FurMark.
Graphics card driver: BSODs appeared even when running without AMD drivers.

Basically, I don't know if the BSODs are due to HW failure or SW issues. I did not experience any in Safe Mode and only 1 BSOD before OS start-up, so my guess would be it is SW/driver related.

End note:

I understand that without the mini-dumps it's much more difficult to help me, but from what I have described above, it seems that the problems are interlinked. Is it probable that solving one will resolve the other (e.g 4->3->2->1)? If so, what should I do next?

I also understand that a Repair Install might be considered the best solution at this point, but given that the BSODs occur at random and the installation is through the OS, I don't want to risk a BSOD mid-install.
Ideally, I would like to resolve this in any other way possible.

Again, thanks, at least for reading through the above

If you ran memtest86+ for at least 8 consecutive passes without any error, better you plan for a clean reinstall.

Repair install might not solve all the corners of your issue.

Well, if I wanted to avoid a repair install, then I really want to avoid a clean reinstall. Regardless, thank you for the reply.

UPDATE: The good news is that, somehow, the system began generating dump files today, so based on the two that I have so far, I managed to attach per instructions the required zip.

Also, I did not run the memtest86+ 8 consecutive times (did it only 3 times), so I will do that now. What I did in the mean time though is remove one RAM module and for 6+ hours no BSOD, so maybe, it is the RAM.
I kind of hope it is the RAM, because that is a better solution than a clean install.
I'll post back once I have something to report.

The crash dumps are saying that there is a possibility of memory malfunctioning, but you should apply another keyboard there, at least as a test basis.

Arc, thank you so much for helping out and SOLVING my problem!

The problem was my 2nd RAM module being faulty. I re-tested them, this time individually in slot 1, and while the first one passed (am running my system for approx. 2 weeks w/o a single BSOD), the second one failed as early as OS boot.
I feel kinda stupid for only running memtest 3 times, but lesson learned and problem fixed - both more important than my pride.

As for the issues with sfc /scannow and Win Update; these are not as critical, so I'll try to fix those when I have some free time. If I'll need help, I'll link to to the appropriate subforums.
