I had had 2 BSOD in the last 3 days
Microsoft gives various guesses
Bad RAM
CPU does not match the BIOS version
I have had this PC for 3 years so I do not think it is the latter (ASUS P5 + E8500)
Blue screen view (Nir Sofer) gives fltmgr.sys as the cause
MS knowledge base says to check your AV
I have the 2 mem dumps
I will now go to try memtest86 4.20
Ho-Hum
ps I have run sfc /scannow & chkdisk full already
Memtest86 gives 100% pass
I have run out of ideas
I have now ruled out all the hardware as far as I can.
That was more a matter of form really, anyway it’s done including changing the wireless card before the last BSOD.
I think that I am looking for a driver conflict or some such
I have a total of 36 Processes running on boot and these include Wireless Card driver (1) and Avast (2)
This is my standard config’, I’m almost in ‘safe mode’ anyway
There is not much left to get rid of is there
Bug Check Code - 0x00000024
Caused by Driver - fltmgr.sys
Crash Address - ntkrnlpa.exe+cdb3f
Stack Address 1 - Ntfs.sys+19fff
Stack Address 2 - Ntfs.sys+a4a6f
Stack Address 3 - ntkrnlpa.exe+a5e22
Any ideas welcome, I don’t want to uninstall Avast - I’ve got another year (license)
Have uninstalled Avast 
There isn’t anything else to do
I’ll keep checking here.
Open a bug ticket?
http://support.avast.com/index.php?_m=tickets&_a=submit
A ticket wouldn’t really do much as there is no mention in any log/output that Avast is involved at all. So it’s just me saying I don’t have anything else running and now not even that.
On the other hand there are several BSOD’s around here & one even mentions fltmgr.sys
Anything that has a set of filters running real time could conflict I suppose
Normally Blue screen view, gives a number of drivers that night be involved, were there any other drivers mentioned ?
That’s it I’m afraid. The same each time.
I was hoping there might be some tenuous link, but like you you I don’t think this is avast related as no avast related drivers in the minidump info.
I did a really good search & tried everything I could find.
I got rid of Raxco PD11 'cos others had issues of some sort or other.
I got rid of Mil Shield 'cos it loaded with windows.
I swapped out my wireless card for another (exact same) 'cos there has always seemed to be a fight with Avast as to what loaded first & perhaps a hardware fault. Could still be those drivers I suppose.
But even if everything runs without any issues for a year I will not have proved anything.
I still have a year on my Avast AV pro license, so perhaps wait until another release or another BSOD without Avast - and then what?
I thought that I would add an oddity
Both BSOD’s actually happened whilst I was using IE9
The cause details were the same but the first is logged (Vista Problem Reports etc) as IE & the second as Windows.
I honestly don’t know what else to suggest.
Though it wouldn’t hurt to send the dump files in the hope something might be found to at least point you in the right direction, if it isn’t avast related.
I don’t know if you have set the Startup and Recovery settings to create a kernel memory dump as that provides far more information, e.g. everything in memory at the time of the BSOD.
In C:\windows I happen to have a 300MB MEMORY.DMP
Now then, what brave soul is going to volunteer a name etc ;D
Give the zip file you are uploading a unique name (e.g. forumusername-mem-dump.zip, etc), so they can identify it. It might not be a bad idea to create a text file (readme.txt) with any relevant information, avast topic URL, user name, etc. etc. in the zip file. Not to mention posting the name of the file you uploaded in the topic acts as another searchable reference.
Up loading to ftp_incoming
DavidCo_MEMDUMP.rar (56.5MB rar)
I installed another (free) AV for the time being.
No BSODs yet!
What I did notice however was the state of the network icon
When using Avast the icon would show as ‘Local and Internet’ to begin with, but this would change to ‘Local only’ if I was not actively using the internet.
If I then launched a browser it would connect and then the icon would change to ‘Local and Internet’ until I went ‘inactive’ even if I was just reading an article.
Clicking a link would change it back to ‘full’ etc.
With the temp’ antivirus the icon is always at ‘Local and Internet’
The BSODs occurred during browsing sessions and maybe, just maybe, that change is linked to a conflict between Avast & my network card drivers (wireless)
There is another post mentioning (no BSOD) something similar with a wireless card.
I cannot take the chance that a new release of Avast might have solved the issue without a positive indentification of some sort and that seems to me to be a chance in a million.
I don’t think it Avast causing the problem. I think it could be the firewall. The Firewall & the newer version of Seamonkey & Firefox don’t get along. I have outpost firewall free version. Other firewalls may be a problems as well.
