Windows 7: BSOD with Qualcomm WLAN(?) - BCCode d1, 4a

I finished MemTest with 12 passes without any errors. Verifier is now running as listed (I hadn't noticed that change in options until you pointed it out) and I will update as soon as it hits something. It didn't blue screen on boot this time though.

Edit: With regards to this, is there something to consider if DriverVerifier is actually being stable? What sort of time frame would I be expecting a crash? I can't precisely test any video games due to lack of a video card at this point.

Just to clarify driver Verifier is not a buggy program, it finds drivers which have bugs in them
then bugchecks the machine before any data gets corrupted as a result of a real crash caused
by that driver.

If it doesn't crash after 48 hours it probably won't.

We know that nVidia has issues with the current drivers for the 7xx series of GPUs.
If doesn't bugcheck with the GPU not installed and it does when the GPU
is installed then we have a probable cause.

Another thing, to check if verifier is enabled correctly:

Run and elevated command prompt and type in verifier /query.
Start Menu> CMD - right click and Run as administrator.
type verifier /query hit Enter and post a screenshot of the window.

The screenshot doesn't contain all the drivers list but as long as you didn't choose any Microsoft
drivers, as stated in the 6th step in the tutorial, its looking good .

Followed the instructions to the letter, so we should be good with regards to that.

In any case, if it is the nVidia card, are there any known work around solutions? A previous more stable version of the driver perhaps?

Not at the moment unfortunately .
We could test other possible, but less likely, suspects such as the PCIe slot or PSU.
What is the make and model of your PSU?

CORSAIR HX Series HX850 850W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready - Newegg.com is the power supply being used.

Is it possible the sort of behavior could be caused by a bad connection of the PCIe slot? I'm not entirely certain, but upon removing it, there may have been a latch that was not properly connecting on the slot. It's a long shot, but the thought of a video card being entirely useless is rather disheartening.

Edit: Alternatively, though perhaps excessive, since we did have that previous BSOD without the video card... since the memory came up fine, would it be worthwhile to do a full reinstall, install drivers without the video card, then install the video card + drivers for it? I only mention this because the Intel Driver Utility STILL refuses to recognize the chipset drivers and this is somewhat concerning.

The online utility is useful but it's not perfect. It is not a part of intel its a part of Husdawg LLC,
an independent company.
If the GPU wasn't seated correctly it will cause issues which one of them is a bugcheck.
The last verifier enabled bugcheck didn't show any definite cause except for some pending threads
which could just be a function of Driver Verifier itself.
The GPU will be usable once nVidia releases a new driver.
A clean install is always a good idea, does it worth the hassle? that is up to you.

BTW you need to update your system specs.

Thank you for reminding me about system specs - I forgot that was even there!

I think, given the strangeness of problems and given that DriverVerifier is not finding it... and the GPU being the cause would effectively result in no solution at the moment, I'll take the chance to give it a clean reinstall from the Windows 7 Install. Maybe there was a corruption on the .iso or something that I had been using.

To make sure I understand the process entirely though, I should:

1. Wipe the mechanical internal drive that the operating system is NOT on.
2. Reboot with the Windows 7 Install DVD.
3. Have Windows 7 format the SSD and reinstall upon that.
4. Run through the ASUS Z87-PRO DVD and install all relevant drivers.
5. Immediately go to Intel and update drivers from that.
6. Update any remaining drivers we located on this thread that had not been updated (like the Qualcomm).
7. Reseat the GPU.
8. Get latest drivers from NVIDIA for the GPU, rather than use their DVD.

Does that sound like an accurate assessment of the process?

I would follow this tutorial if you are unsure of the installation process.
If you have no important date on the drives, then yes format all of the storage
connected to the PC.


Before the reformat, as long as you have internet connection I suggest you download
all of the latest drivers from your motherboard's OEM webpage as well as from nVidia's webpage.
Never use the driver CD that came with the component as they are more often than not,
outdated by the time you install it.


Good luck and post back with results!
