Windows 7: BSOD driver_irql_not_less_or_equal

BSOD driver_irql_not_less_or_equal

I've been having recurring bsod errors lately. It went from once a month, to once a week, to once a day, to a few minutes after startup.

I haven't really changed anything... they have just become more frequent. I'm almost positive it's a driver issue. I ran driver verifier with the 3 that create false positives disabled and it caused a bsod on startup everytime. I couldn't figure out what was causing it though.

I need my pc fully operational so I can work so any help would be more than appreciated!

I've done some analysis of my own and it looks like ndis.sys is the cause. I suspect an issue with the nic card interaction given my asus p8p67's dual onboard nic cards. I've disabled one and activated the other. Maybe this will resolve any issues.

Answer the question asked by koolkat77 first, and then have a look.

► Your nvidia display driver seems to be very old.
Code:
lmvm nvlddmkm
start             end                 module name
fffff880`0f28a000 fffff880`0ff01000   nvlddmkm T (no symbols)

I doubt there is some issue with your Graphics memory

Please do it: Video Card - Stress Test with Furmark

► Most of the dumps are indicating to Memory Management failure. In such a situation, the best option is to go for memtest.
RAM - Test with Memtest86+
Run it, at lease 8 passes, if possible, overnight.

Enable Driver Verifier:
Driver Verifier - Enable and Disable

Let us know the results of the tests, and if there are subsequent dumps you got, post those for analyzing, with Driver Verifier on.

I decided to take a shot at it myself. I took a look at the minidumps and noticed that from all the recent bsods (the ones that are the culprit and real issue) there was a pattern.

In the crash stack of all minidumps I noticed ntoskernl.exe and ndis.sys. Under all the driver_irql_not_less_or_equal.... only ndis.sys could be found in the crash stack of all of them.

Network Driver Interface Specification is what it stands for. So obviously all my driver_irql_not_less_or_equal problems are caused by a network driver. My p8p67 has two network cards built in. They are intel and realtek cards. I was using the realtek card. I disabled it and switched to the intel one. I haven't had a bosd since.

Out of curiosity I googled "realtek nic p8p67 driver issue" and found a ton of related problems. So that's that.

It's my first time analyzing a dump and I while I do have a CS degree with a minor in secure computing and networking I just used bluescreenview and a bit of knowhow. How did you reach the conclusions and suggestions you found?

After attempting it myself the solution seemed fairly obvious. I'm curious if there is some relation that is easily missed (I'm a bsod noob) or if you just paste the same suggestions for fixing it (the most common culprits) and then take a look if the basic fixes don't work. I understand the latter is necessary for the amount of volume you folks probably see day to day.

Thanks for your assistance,
Ganon
