Solved Occasional random BSOD from various programs, frequent app crashes

unkl12345 · Oct 11, 2012

Hi all,

I built my own machine about two years ago, and everything ran smoothly until recently. I added 8GB of extra ram back in May -- the only hardware update I've made.

Starting in August, I started to get frequent crashes (maybe 10-20 times/day) of my most used applications: Firefox, MS Outlook, and Netbeans. I also get the occasional BSOD, a few times each month.

There were a large number of Windows updates and Office updates that were installed in the middle of August, but I can't say for sure that my problems started with any one of them.

I tried updating the BIOS today to the latest one available, but the most recent BSOD occurred after that.

Can you please help??

edit: the majority of BSODs are caused by ntoskrnl.exe, but not all.

Welcome aboard.

Your crash dumps are not showing any finite probable cause. In such a situation, it is better to enable Driver Verifier to monitor the drivers.

Driver Verifier - Enable and Disable

Run Driver Verifier for 24 hours or the occurrence of the next crash, whichever is earlier.

Let us know the results, with the subsequent crash dumps, if any.

Thanks, Arc. I enabled driver verifier on Friday and left my machine on over the weekend. I'm continuing to have frequent app crashes, but unfortunately (?) no BSOD.

Anything else I can try?

We need the dumps with verifier enabled.

unkl12345 · Oct 15, 2012

Well, there are no new dumps, since I haven't gotten another BSOD. So, I guess I'll just leave verifier enabled and come back to this thread after my next BSOD...

Thanks again.

Okay, I finally got another BSOD. I've attached the memory dump as a .rar file. (Sorry for the multiple files -- I didn't know any other way to get around the upload size limits.)

I crashed a second time shortly after this one, so I'll upload that memory dump to another post.

Arc · Oct 29, 2012

Very difficult to download all those, I dont have a good net speed.
Can you upload the minidumps though? Or I am calling somebody else to have a look.

unkl12345 · Oct 29, 2012

Full memory dump from the second crash, attached. Minidumps to come next.

unkl12345 · Oct 29, 2012

Okay, Arc, here are the minidumps for these two crashes.

You update the display driver.

Code:

lmvm nvlddmkm
start             end                 module name
fffff880`0f0b3000 fffff880`0fdd1000   nvlddmkm   (deferred)

Get it from Drivers - Download NVIDIA Drivers.

Also, it is Realtek RTL8168D/8111D Family PCI-E Gigabit Ethernet NIC.

Code:

And, it is very old.

Update it from Realtek

Let us know the results.

okay, i've updated both drivers, and i just got another blue screen. here's the minidump for that crash.

also, i crashed three other times between the time i updated the nVidia driver and the time i updated the realtek driver. this is highly unusual. i live in an area that was affected by Hurricane Sandy, and my internet connection has been unstable for the past few days. we have also been experiencing minor power fluctuations. is it possible that these things are somehow contributing to the problem?

Arc · Nov 3, 2012

Disable driver verifier now ... and then report the situation back.

unkl12345 · Nov 12, 2012

there doesn't seem to be any improvement with the updated drivers. here's the latest minidump.

Arc · Nov 13, 2012

You may try it: NVIDIA DRIVERS 310.54BETA

unkl12345 · Nov 29, 2012

no change. the problem is still the same. here's the latest minidump.

Arc · Nov 29, 2012

This time it failed to provide any result.

alright, i enabled driver verifier again. here's my latest crash.

How long have you ran verifier? Is it the single one crash with verifier enabled? In that case, we may need to think differently.

► Test your RAM modules for possible errors.
How to Test and Diagnose RAM Issues with Memtest86+
Run memtest for at least 8 passes, preferably overnight, per RAM module per slot.

► Stress test the Graphics Card using Furmark.

hey arc, it looks like one of my RAM sticks was bad. i'm sending it back to Corsair for a replacement, and i expect that this will fix my problems.

thanks, so much for your help! you were awesome.

Arc · Dec 11, 2012

That's a good news that the problem is traced out. Let us know the results after replacing the RAM stick

And, let us know one more thing ... is it still crashing, if you dont use that particular problematic RAM module?
