Resolved Persistent BSOD IRQL.... fltmgr.sys

Hi, out of nowhere, I have started getting frequent (every 10-15 minutes) BSODs. It is always the same... DRIVER_IRQL_NOT-LESS_OR_EQUAL and it references fltsys.mgr. It does not seem to initiated by an action like PRINT, etc. Just surfing the net, saving something, writing something, etc.

I looked it up and like most BSODs I ran the following:
Malwarebytes
SFC
Chkdsk
Windows Memory Diagnostic
My RAM is 4 months new.

I have been updating drivers starting with the graphics card. I was going to just do system restore but my last restore before this all began 4 or 5 days ago (appx Sept12) was in MAY!! So, I didn't.

No luck so far. Any suggests on how to proceed? I wanted to do a backup but I don't think it will stay stable long enough.

Thank you.

 

This should point the finger at the problem.

 

Retiredlearner: I will ck that out. Can I assume that I have to do that right after a BSOD or it will always show the results of whenever the last BSOD was? Is it intelligible to the typical computer user?

Evan: Hard drive is an SSD. Haven't tried it in Safe Mode. I used app called DriverMax for updates and there are a lot, like 10 for Intel stuff alone! I found an actual Intel driver update utility and it only found 1. Did that. Didn't see a BIOS reference unless you are talking about firmware and that is a different thing. My nVidia card and the Realtek stuff on the mobo are updated already.

I hope that answers your questions. Thanks again,

 

Using a 3rd party App to update may be your problem. If the updated driver is not MS approved this could cause it.
Its much better to go direct to the hardware manufacturers website to see if there are any new drivers for your comp and download from there.
Carry out the check when your comp is running stable as all events should be logged including the last one.

 

The Graphics card driver is from the mfg site. Otherwise, the others that I got from the 3rd party app made no difference on my BSODs, good or bad. I just went to the Gigabyte mobo website and almost all of their listed drivers are ancient (2013). Not sure what that means or what it says about Gigabyte. My BIOS is an first version F1 and the driver is unchanged.

I tried copy/paste on "%SystemRoot%MEMORY.DMP" but nothing opens it. I found out that my 256k dump files go into a minidump folder. Looking for best way to read it. I found one app called Blue Screen View. All it says is that it is the fltmgr.sys driver, Microsoft Filesystem Filter Manager. Should there be more info?

Thanks

 

The impression that I get from the Gigabyte website is that the F1 version (that I have) driver (they have 3 different BIOS versions listed) is still unchanged from the original one (dated 2013). I don't think there is an update. Mobo # Z87-DS3H

Thanks.

 

Hi Evan, The F3 zip extracted to my desktop. When I pressed autexec.bat, I got a message that it was not compatible with 64-bit. I emailed Gigabyte for a new driver. I will let you know unless you have some new ideas on this. Thanks.

 

I figured out how to update the BIOS via its internal Q-Flash app. It is now F3. Since that and some Windows Update updates, the fltmgr.sys BSODs became more frequent. When working in Safe Mode, it did not happen !! The Shutdown period has increased, too.

Should I run my 2 8Gb sticks through Memtest? Trying out 1 stick at a time now.

 

The RAM stick test results are that they both caused the fltmgr.sys BSOD. One was faster than the other but that may be just the seeming randomness of this problem. I will try to do more in Safe Mode again today to be sure that it is BSOD free. Been on the computer for 20 minutes this morning and so far so good. Random. Thanks.

 

Have not forgotten, just busy. Thanks! I will do the clean boot next. Unfortunately, it can be 5 minutes or 5 hours between BSODs.

 

Just wanted to add that for the last 2 weeks, I have not had one BSOD!! I am not sure what to attributte it to. I never did the msconfig clean boot investigation. Seems like Windows has a self healing capacity if you reboot enough times!! Haha. Now that I have said that, I expect a BSOD soon. I am likely to return but for now, things are stable. THANKS!!!

 

On re-reading your Thread this made me wonder whether the RAM you installed are matched (paired identical) or were they purchased as individual sticks?

 

Actually, one stick went bad and I sent both back to G Skills for warranty replacement. I have to assume that they sent me a matched pair.

 

Yes. One would have to assume that. (I have Gskills in my main comp) matched pairs of course.
