Hello there!
I have very recently aquired a (brand new) laptop (like 3 days ago), Acer Aspire V15 Nitro, with the following specifications:
Windows version: Windows 10 (64 bits) , 10.0, build: 10240
Hardware: Aspire VN7-571G, Acer
CPU: GenuineIntel Intel(R) Core(TM) i7-5500U CPU @ 2.40GHz Intel586, level: 6
4 logical processors, active mask: 15
RAM: 8500232192 bytes total
Graphic cards: NVIDIA GeForce 940M and Intel(R) HD Graphics 5500
(not sure we say "graphic card" in english, is it like graphic display instead?)
(not sure it is relevant here but I prefer providing as much info as I can)
Everything seemed fine. I then installed Windows 10. It still seemed fine, though. I use this laptop to play games and work (drawing with softwares), and everything seemed fine at first. I only use WiFi but never had any issue with it when I did so with my previous computer)
However, time to time - at random - a BSoD appears with the error message:
SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (qcamain10x64.sys)
It is difficult to determine when the error occurs, but it oftens happen when I play after maybe 30 minutes. It also occurs while I browse on the internet (without playing) and it also happened once as I was shutting down the PC.
Since it occurred, I tried several fixes. I am not so good with computers, so it's hard for me to determine the problem and how to solve it. So I updated drivers, mostly graphic cards as the researches focused on these. In my case, I tried different ways to update my NVIDIA GeForce 940M, including GeForce experience (I then learned it was not recommended). I also did the uninstalling (using DDU) and installing the graphic card back. It seemed to work, but it ended up leading to another BSoD, DPC_Watchdog_Violation. I searched again to solve this issue, but failed. It led my performances very low, as I had many "jumps" of lags in game. I then did a restoration of a previous restore point, hoping to completely get rid of this second problem, as it was much worse than the previous. This one was solved.
Now, I still have the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (qcamain10x64.sys) even after a restore.
I tried several kind of fixes such as: sdc /scannow or CHKDSK C: /F /R
None found any issue. (as if nothing was wrong)
Since I feel pretty stuck and that a brand new computer shouldn't work that way, I would like to know if anyone knows what I should do to fix my computer, because I don't know what to do now.
Here is the dump file info (provided by WhoCrashed):
On Fri 28.08.2015 23:34:09 GMT your computer crashed
crash dump file: C:\WINDOWS\memory.dmp
This was probably caused by the following module: qcamain10x64.sys (0xFFFFF800B9A88D2A)
Bugcheck code: 0x7E (0xFFFFFFFFC0000005, 0xFFFFF800B9A88D2A, 0xFFFFD00171754748, 0xFFFFD00171753F60)
Error: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
file path: C:\WINDOWS\system32\drivers\qcamain10x64.sys
product: Driver for Atheros CB42/CB43/MB42/MB43 Network Adapter
company: Atheros Communications, Inc.
description: Atheros Extensible Wireless LAN device driver
Bug check description: This bug check indicates that a system thread generated an exception that the error handler did not catch.
A third party driver was identified as the probable root cause of this system error. It is suggested you look for an update for the following driver: qcamain10x64.sys (Atheros Extensible Wireless LAN device driver, Atheros Communications, Inc.).
Google query: Atheros Communications, Inc. SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
(it always displays the same error)
I did try to find the driver corresponding, but all I find is third party driver (I even tried to install one in the end, but it said it failed anyway). I checked on the website of Qualcomm Atheros ( http://www.qca.qualcomm.com/ ), but did not find it. Google search wasn't helpful neither.
Should I uninstall it and check for an update? Would Windows be able to find the driver again? Or may the issue be from something else? (I am not comfortable uninstalling something else than graphic driver since I'm not sure to find them again in case there is an issue; tell me if I shouldn't hesitate and see if this changes anything... I just am a bit scared to create yet another issue)
I would like to get rid of that BSoD, if anyone could please help me to find a way to solve this issue. My driver manager says the driver is up to date and that there is no issue with it.
(also, I'm not good with computers, so tell me if there is an information you need and the way I can provide it, if needed)
Thanks for your time.
PS: Sorry if my post is too long, I tried to make it as short as possible
