    Random BSODs cant pinpoint why...


    So i bought a new rig and now i am having random bsods - which can occur no matter how loaded my pc is at the moment.

    I have stress tested gpu and cpu - but everything was ok there no bsods what so ever. Then i memtested ram for 10 hours straight - i got 11 passes and 0 errors. I tried driver verifier but nothing happened... got 2 different bsods while writing this post in fact, but was working for 3 hours without bsods previously -> these were d1 and 1e bsods.

    I will attach my dump files below.

    Here is additional reading - what i posted on the support forum of the company that send me components :

    I was getting random BSOD's all day today ;/ No matter if the system was idle or under full load... it would crush in the most unexpected time with the irql_not_less_or_equal in ntoskrnl.exe file error... well that is something related to the TCP/IP stack ... so i started to try and isolate the problem, installed latest driver for everything... then i started to stress test the system monitoring temp e.t.c of my CPU and GPU, the CPU never went above 71C under full load for 30 minutes in prime95, i furmarked GPU but it didnt went above 85C so I rulled those out, then i memtested my ram (just 1 go though - 30 min - but it passed - i will leave it testing overnight today to rule it out completely).

    I noticed that bsod was more likely to occur when i am stressing my wi-fi dongle, so i updated the drivers for it too, but this didnt help ether. Sometimes after BSOD pc didnt recognise that the dongle is plugged in at all, till i restart the system. One more strange thing is after i installed windows my Belking Wireless G dongle would never recognize as plugged in... In any USB port it just doesnt register no matter what (on my previous PC under WIN7 it still works fine) - on my new pc however it is only possible to make it work when i plug in my D-Link dongle - connect to the internet - unplug it - plug belkin in - then it recognises and works in any USB port. It might work for several restarts but then it might stop to register again till previous operation is executed - i find it really weird. You can plug anything else in though any time (like flash drive, keyboard and mouse - both usb - both never stopped working <- they are plugged into the usb 2.0 ports though) it will work. Just belkin is weird.

    I decided to test the system using driver verifier it did spit some errors, but they were unrelated and only because i mistakenly used low resource simulation option as well. I uninstalled daemon tools and all other potentially hazardous programs and it went ok for like an hour - and i felt relieved but then it bsod while i was browsing - shame. I tried reinstalling windows several times (different versions of it as well) but it still bsod.

    I still felt like it was something related to the network drivers but definitely not the dongle ones coz i used them for several years in windows Vista and in windows 7 with no issues. The only thing network related was atheros gigabit lan controller so i googled my motherboard name + atheros lan + bsod and i was given this link (https://www.sevenforums.com/crashes-d...nder-load.html), same motherboard similar problem. He did the following thing:
    using driver version 2.0.14.15 and deleting L1C62x64.sys from windows\system32\drivers (but not from DriverStore), the problem seems to be gone.

    I've left torrents running for 3 hours now, and all is fine.
    I'll mark the thread as solved
    So i did the same and there are no bsods for an hour now (fingers crossed), but system could go for up-to two hours before bsod before, so i am not out of the woods yet, so the question is - is my motherboard faulty coz of the driver + belkin thing or is this normal?

    P.S> if another bsod happens i will try reverting nvidia drivers (although doesnt look like gpu is the culprit here), if bsod after that - then i will replace gpu with the spare ATI 6870 if bsod after that i will rma everything, or does it sound like it's faulty already and i have to rma it?
    P.S>> soz for so much text just wanted to elimination as much questions as possible.
    I hope someone will be able to help me to narrow it down.

    Thank you in advance.

    I've had random bsods before, I'm dealing with them now actually, and as random as you say they are, have you tried looking into your psu? That's what I'm doing, 95% of the time ( in my experience) random bsod are psu related, especially if all your hardware tests are coming back.negative

    after stressing my system i got 2 bsods 1 after another - here are dump files.

    any ideas? it's like cpu locked or something. So is it psu or cpu related? cpu temp never exeeded 72C same goes for gpu and the temp inside the case was 32C ... so not overheating.

    I assume you've got a power strip, so your not directly connected to the wall, what brand are running? Search the forums for "hardware power consumption" its my thread where I was given some really good info on power supplies. I also wouldn't overlook keeping your CPU a few degrees cooler, I'm on my way now to get the corsair h60 h20 unit, nothing fancy but it keeps nice and cool.

    You have two 0x101 crashes and a few Unknown Module crashes that do not indicate what module caused them. The Unknown Module crashes could be related to the 0x101 crashes, or they could indicate a virus on the system.
