Hi!

I am having a problem with those damn BSOD..

It started a few months ago (2 or 3 months) and it has been happening at least but mostly once a day when certain conditions are verified. I am certain that 90% of the times that my desktop crashes presenting the BSOD is when I am online and downloading or updating something for example using steam, at speeds greater than 6Mbps. It is almost guaranteed that sooner or later if I am downloading at speeds of at least 6Mbps, my computer will crash displaying a BSOD. I can surf the web without any problems, though if I am browsing for a while, the first game a play either single player or multiplayer I will have fps drops that get fixed as soon as I restart my desktop.

Even playing probably heavier games in terms of resources, I never get the BSOD.

Yesterday it was the first time that I had 2 BSOD on a row and the 2nd time it went down I only had time to connect to the internet and teamspeak before it went down again (BSOD 18h35 -> restart, connect teamspeak without doing anything else -> crash 18h38).

And for a few days now it has also been happening the strangest thing.. I click to turn off my desktop the normal way and it turns off but after 2secs it comes back on again and sometimes it goes all the way to windows and I have to click turn off again, and sometimes right after it restarts on its own, it turns off almost immediately on its own. 😵?

My rig is:

Intel i5 2500K 3.30GHz
Asus P8Z68-V PRO GEN3
Geforce GTX 970
Corsair TX 750W v2
SDD 250GB Crucial MX100+HDD 1TB Samsung HD103SJ
Win10 Pro 64bits
2x4GB DDR3 PC3-12800 G-Skill
Cryorig h5
pen usb wireless asus n-53

For more than a year I OCed my CPU to 4.2 and never had any problems, so the BSOD didn't start when I OCed it. But yesterday when I turned on my computer and before starting to load windows, it displayed a message saying that some setting is wrong with my oc and to go to setup to change it, since without doing that I wouldn't be able to log in. I went to the bios setup and honestly didn't find anything bad but either way I just loaded an earlier configuration I had before OC. After that, windows started normally but after an hour in, that's when those 2 BSOD that I mentioned earlier happened.

Using bluescreenview I can see some of the dumpfiles and for example those 2 bsod on a row on the first one it says caused by fwpkcInt.sys and the second one says caused by mwac.sys.
But I can see some others like ntoskrnl.exe, mslldp.sys, avc3.sys.

I would really appreciate any thought and help on this matter!

Remove over clock until we fix the BSOD

MSLLDP.sys is a new one on me: Microsoft Link-Layer Discovery Protocol service
avc3.sys is part of Bitdefender - try updating it
ntoskrnl = New Technology Operating System Kernel - Its windows, it often gets blamed for errors caused by drivers or other things.

Try running an av scan or maleware scan with malwarebytes (though bitdefender has been known to block installation of it)

can you download and run who crashed - its like BSV but the summary is easier to read
It will create a summary and help show what BSOD you are getting

Copy/paste results in here and I see what I can do :)

Thank you both for replying.

The had reverted the oc just before those two crashes in a row, and I've maintained it non-oc since then.

I have malwarebytes installed together with bitdefender and I have ran a scan on both and they found nothing.

Yesterday I realized I may have done a stupid mistake by using ccleaner as I always do, without thinking that it would delete the dumpfiles of the crashes I had before.
But today it crashed again, so I only have this dumpfile to report, and after I used the software you advised to, here is the analysis:


Crash Dump Analysis
--------------------------------------------------------------------------------

Crash dump directory: C:\WINDOWS\Minidump

Crash dumps are enabled on your computer.

On Sun 05/02/2017 02:06:33 your computer crashed
crash dump file: C:\WINDOWS\Minidump\020517-7250-01.dmp
This was probably caused by the following module: tcpip.sys (tcpip+0x15F665)
Bugcheck code: 0x19 (0x20, 0xFFFFB6893E47E7B0, 0xFFFFB6893E47E7D0, 0x4020006)
Error: BAD_POOL_HEADER
file path: C:\WINDOWS\system32\drivers\tcpip.sys
product: Microsoft® Windows® Operating System
company: Microsoft Corporation
description: TCP/IP Driver
Bug check description: This indicates that a pool header is corrupt.
This appears to be a typical software driver bug and is not likely to be caused by a hardware problem. This might be a case of memory corruption. More often memory corruption happens because of software errors in buggy drivers, not because of faulty RAM modules. This problem might also be caused because of overheating (thermal issue).
The crash took place in a standard Microsoft module. Your system configuration may be incorrect. Possibly this problem is caused by another driver on your system that cannot be identified at this time.
------------------------------------------------------

I am sure I'll get more crashes in these following days so when that happens I'll use this software again and paste here the reports.

Today I've also ran memtest for 2hours (I know it is not enough.. but I intend to run it again for at least 8hours during bedtime) and it found no errors.
Also performed the command sfc /scannow and no errors too.

And is bitdefender a bad pick? I mean, is it problematic compatibility wise? I have a license till June that I won in a giveaway but I would ignore it in an instant if you do think it might be problematic since one of those crashes was related to bitdefender.

I am more likely to blame malewarebytes for the errors over Bitdefender but I have been wrong lots of times before.
tcpip.sys is your internet so problem could be lan drivers or a conflict between the two scanners. I would update all LAN drivers on PC and see if it fixes it.

Is that the latest version of malewarebytes as it can cause crashes. I would take it off first as its easier to uninstall than Bitdefender is, and slightly safer as otherwise you have to use defender.

I have read advice to just use defender over all other scanners but the results of all AV tests seem to point in opposite direction

Can you follow option one here: http://www.tenforums.com/tutorials/5560-bsod-minidump-configure-create-windows-10-a.html
and then do this step below: Small memory dumps - Have Windows Create a Small Memory Dump (Minidump) on BSOD

that creates a file in c/windows/minidump
copy that file to documents
upload the copy from documents to a cloud server and share the link here and someone with right software to read them will help you fix it :)

I see. I am using bitdefender because of those tests too.. I was using avira free edit but then after winning that giveaway I started using bitedender and was considering buying or extend that license after the period of the one I am using ends, because it really seems a nice and light weight software.

I have disabled malwarebytes for now to see if the problem persists.
And it is not the latest version of malwarebytes, I believe it is still the 2.2 version.

And I am sorry for this dumb question.. how do I update my lan driver? Is it by going to devices -> network adpater -> update driver? If it is, it always says that there is no update.

On network adpaters I have:
.Asus usb-n53 802.11a/b/g/n network adpater
.Intel 82579V Gigabit network connection
.Qualcomm Atheros AR9485 wireless network adapter (this one is disabled because I don't use it)

And here is the minidump file of that crash:
https://drive.google.com/open?id=0B5yJWmO0q-LhWlh4R0cxMUgzNnM

Thank you again for your patience.

wait and see what dump files show (I can't read them but Paul can)

Its possible you already have the last lan driver for your motherboard as there are no win 10 ones so its probably using the win 8 ones already. You can find them here

I had Bitdefender Total Security 2016 but I thought i needed to upgrade to 2017 to keep it going, and mistakenly overpaid my subscription so now I have 2 1/2 years protection on the 2017 version, I won't be swapping for a while :)
I like Bitdefender, as I like being able to tell PC when i want to do a scan... its been a few months but its ability to detect bad downloads before installing them is top notch so I am not too worried.

Never had any problems with it.
