Bsod - irql_not_less_or_equal

My comp has been running fine for over a year and a half, not a single blue screen until yesterday night, I got 4 in a row, I did some googling, I thought it was the Atheros driver, I updated after my 3rd BSOD, I thought it did the trick, but I just got another BSOD. Attached is the dumps. Please let me know if the other options are needed to, I'll be visiting the forum regularly for updates. Thanks ahead.

EDIT: edited with proper attachment

edit2: added another dump file since the last time i posted.

Hi, Yeah sorry there, I initially did the scan and got impatient, didn't think there was more to the program, edited with proper attachment, thanks ahead.

Sorry again, I cannot read the dumps still now.

I will ask others if they can.

These appear to be caused by a very outdated D-Link Wifi adapter card driver, dated Oct 5, 2009, which is pre-Windows 7. You will want to look for any updates to the drivers for your D-Link card, and if there isn't, it's time to start looking for a replacement card.

Analysts:

All crashdumps show a very consistent behavior, with all of them being identical save for the usual differences expected from Windows environmental changes caused by separate boot-ups. This shows us we're most likely not dealing with a hardware issue, otherwise it'd be erratic. The callstack is also suspicious:

Code:

This situation is caused in x86 environments because the stack unwind requires symbols for the drivers in order to unravel properly. This is in contrast to x64 environments, where stack unwind information is baked into the driver modules after compiling, which therefore does not require symbols to properly unwind a stack with drivers that have no symbols available. Since this bad frame in the stack appears sandwiched between two perfectly good Windows kernel modules (nt and ndis), then it's even more evident we're dealing with some 3rd-party driver and not just from some unwind fluke, and most likely it's a network driver since we're dealing with ndis in this thread. It's time to dump the raw stack to find what's sitting inside. Use the typical method for dumping raw stacks (!thread output is slightly different in x86 and x64 environments):

Old and stale driver. Definitely needs some freshening up.

Thanks for the reply, I'm not too familiar with too much technical stuff, I initially tried to update the driver though, I've probably done it incorrectly since you're telling me it's still a 2009 version. Installing new hardware is not an option for me though, the pc in question is a very small media box pc, just used to run media, don't think anything would be adjustable. I'll try and properly install a new driver when I have time, thanks for the reply, I'll see how it goes n get back to you.

Edit: Also, it's been running an old driver for about 1.5 years now then, any idea why it started acting up now?

It's called code rot, where various things like when standards of utilizing OS environment resources change, the old drivers get left behind doing things the old way which may or may not end up being supported anymore. Also, when new applications and drivers come in, there may very well be conflicts aroused with the old drivers due to them using obsolete - and often deprecated - methods. You may have some software/drivers installed recently or using the PC in such a way now that you didn't before that is now causing the old drivers some grief. The old driver may also have bugs that have been patched with newer versions that are now manifesting. I however don't believe that to be the case here, because since it was designed pre-Windows 7, it was not designed with the new standards in mind, the same ones instituted upon Windows 7 driver developers to write their code in such fashion.

Hey, I've updated the drivers but I'm still getting the BSOD. I've checked the driver details for that hardware and it definitely says 2012, maybe the athr.sys file isnt updating properly. I'll repost the new grab all dump files when I get home.

If you want, it'd also be advisable to turn on Driver Verifier and have it crash a couple times with it on. Those crashdumps will prove most useful. Remember to follow the whole article entirely, as deviating from it will cause unexpected symptoms or create false positives that would lead us off-track. There is nothing it can do that can cause any permanent side-effects.

EDIT: Btw, I also noticed you are not using Windows 7 Service Pack 1. Please install that as it resolves a good deal of bugs that are initially inherent in Windows 7.

Should I try that first before trying the driver verifier?
