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

So. An update is in order.

Attempted to run the Intel Driver Utility, but it never completed. Tried to manually find the Intel USB 30 eXtensible Host Controller driver for Windows 7, and it gives me "This computer does not meet the minimum requirements for installing the software" as an error.

Turned on verifier.exe, crashed instantly upon restart, turned it off, as according to instructions. The current log is attached.

During all of this, the nVidia GTX 760 card has been removed.

Usually when Driver Verifier finds nothing, which is the case we are facing, and the bugchecks are consistently
faulting on core Windows components it's time to test the hardware.

Tip   Tip
  • Pay close attention to part 3 of the tutorial "If you have errors"
  • Test the RAM with Memtest86+ for at least 7-10 passes. It may take up to 22 passes to find problems. Make sure to run it once after the system has been on for a few hours and is warm, and then also run it again when the system has been off for a few hours and is cold.
Post back with the results .

You had previous stately not to check the SSD drive; the link you had provided for checking the hard drives seemed to indicate a CD requirement, while I don't have any burnable CDs at the moment. Is there a utility for checking a Western Digital hard drive from a USB drive?

I meant not to use the CHKDSK utility on the SSD.
For now let's focus on the RAM as it seems to play a bigger role in the bugchecks.

If you don't want to use a CD to test you can use YUMI Multiboot USB Creator to create a bootable USB (instructions are found at the bottom of the page).

Memtest86 is now running merrily along; though I imagine it'll be about an hour and a half before even one pass is done, so full results will not be available until tomorrow.

I will note, aside from verifier.exe having a brief blue screen on an attempt to boot, it seemed to be doing pretty dandy. But I'm not even sure it GOT to really crash with verifier.exe working - it literally crashed on boot. Is that relevant?

Yes memtest is an "all-nighter" type of test, that's normal.

Driver Verifier is designed to crash as soon as it detects drivers trying to commit "bad moves"
in the kernel which will lead to a crash anyway.
The benefit of a crash initiated by Driver Verifier is that the driver at fault is usually
caught red handed, so yes it should have crashed with DV enabled but nothing was detected
which sometimes happens.
That usually suggests a memory issue.
By the way make sure you read Part 3 of the tutorial if errors are found during the test.

Memtest86+ is now about twelve hours in. Seven passes have been completed, with no errors read. I'll leave it running while I am at work today to see if anything else is found - I think it'll get another 4-5 passes in during that time frame.

Given the following assumptions:
1. The memory is fine, if it passes these extra tests with no errors.
2. The video card is fine, since it crashed after being removed.
3. The second internal drive is fine, since it passed a chkdsk.
4. The SSD is fine, since Samsung Magician tells me it is.

Would it make sense to format both drives and just make a clean Windows 7 installation at this point, since it's faulting on core Windows components? I had previously installed off a boot USB - now I have the Windows 7 installation DVD. In addition, it bothers me that the Intel Driver Utility was entirely unable to recognize the chipset drivers, as well as the fact that sometimes drivers just failed to allow me to install them.

It's a fresh computer, so a new installation would not kill me to do.

Assuming that the memory is ok, a fresh installation is always a good idea but we want to avoid
making the same mistakes on the newly installed OS.

I would start backing up the data in preparation for a clean install.
Once that is done I suggest you run driver verifier using THIS METHOD and wait for the system
to crash a couple of times it might shed some more light as to what's really going on.

BTW aside from the SSD being in good condition, is the firmware up to date?

Samsung Magician reports the firmware as up to date of the hard drive.

So - the installation is new enough that there is literally nothing that NEEDS backing up. Just some software like Steam that is easily (and perhaps better) reinstalled. In that case, do I need a full back-up to restore from, or would it suffice to just make a System Restore point prior to using DriverVerifier?

And just to check to make sure I understand, we're essentially doing a DriverVerifier test again, except this time with Force Pending I/O Requests set to off, and waiting for a couple of crashes this time rather than the first one.

By backup I meant your personal files, which you can't reinstall or download.
A system restore point will suffice.

Correct, but these are the settings that needs to be applied (quoted from the tutorial):
Quote:



  1. Go to Start and type in "verifier" (without the quotes) and press Enter
  2. Select "Create custom settings (for code developers)" and click "Next"
  3. Select "Select individual settings from a full list" and click "Next"
  4. Select everything EXCEPT FOR "Low Resource Simulation", "and "Force Pending I/O Requests" and click "Next"
  5. Select "Select driver names from a list" and click "Next"
  6. Then select all drivers NOT provided by Microsoft and click "Next"
  7. Select "Finish" on the next page.
