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

OK just to establish a base line, because we did a lot of steps and some inconsistencies with the bugchecks
are starting to happen, remove any GPU from the system uninstall the GPU drivers completely and run the PC
for at least 72hrs in that configuration, I believe it shouldn't crash if it does post back here as we are looking at a different hardware problem.

And I don't believe that RAM is involved your dumps were somewhat consistent up until now.

Well that last crash is related to your integrated graphics.

Code:

SYSTEM_SERVICE_EXCEPTION (3b)
An exception happened while executing a system service routine.
Arguments:
Arg1: 00000000c0000005, Exception code that caused the bugcheck
Arg2: fffff960001463aa, Address of the instruction which caused the bugcheck
Arg3: fffff8800865df80, Address of the context record for the exception that caused the bugcheck
Arg4: 0000000000000000, zero.

There is a BIOS update, please perform it.

• Z87-PRO - Motherboards - ASUS

Attachment 284787

   Warning

Flashing the BIOS is a risky procedure which when performed incorrectly will run the motherboard unusable.
If you're unsure on how to perform the flashing of the BIOS have a technician perform it for you.
Regardless, performing at you own risk.

It's the iGPU again.

Let us know :) .

You stated that intel updated utility never completed.

asura8 said:

So. An update is in order.

Attempted to run the Intel Driver Utility, but it never completed.

One thing at a time please, let's get the machine completely stable then add piece by piece
that will make the procedure much clearer to diagnose.

Quick note;
Do you have a spare machine (not the new 87 chipset) you can test the RAM on?
