Question

BSOD "dpc watchdog violation"

By whertrtma389 ·
Hello! Please help me!
Laptop Acer Aspire V3-772G
Windows 8.1 for one language
System type: 64-bit OS, x64 processor.
The problem itself: the laptop does not work more than 1-2 hours due to frequent BSOD "violation of dpc watchdog"
Here are all the minidumps: https://1drv.ms/f/s!Aj7SX1fggRNJacumedIUnRZ9p7g
I searched the Internet for a solution to the problem-nothing helped: checking for viruses, checking disks, memory, updating drivers, disabling devices, etc. Also did not help a few clean OS re-installs !!! The laptop was not overclocked, it did not drop, nothing was spilled, the BIOS updated, before that there did not change anything and generally 4 years all worked-flying. From the moment of purchase Win_8 was installed on it, then it was updated to Win_8.1 and further to Win_10. Already asked in this community question, one of the answers was "... your laptop is not in the list of supported current OS Win_10. Installed Win_8.1, but it did not help either. Yes there were BSOD, but these were isolated cases, and after the restart they disappeared for a long time.
So, as far as I understand, this BSOD is not the root cause, but a consequence. With the help of the official program, windbg analyzed mini dumps. There is indicated the error ACPI.sys, but this is not the root cause of BSOD (again, as far as I understood). Using driver verification, Verifier.exe began to look for problem drivers according to the instructions from here: http://www.oszone.net/8736/Verifier#verify
First in the list I selected ACPI.sys, ntoskrnl.exe, and everything that is connected with Nvidia, Intel, Acer, Realtek and there where there is no data. Done. Reboot. Goes out immediately BSOD. Then windbg pointed to Netio.sys. One of the solutions - to disable the Adguard ad blocker - did not help me. Then he began to check everything separately. As a result, the problem was found in the Intel drivers, namely the specific one: iastora.sys with BSOD DRIVER_VERIFIER_DETECTED_VIOLATION error. Again, as far as I understand, here it is the primary source of problems. And now what to do next? Help ...
Added: in the device manager put the standard controller SATA AHCI. Iastora.sys error was lost. But the bsods also stayed ((Only now due to an error (after checking ntoskrnl.exe) DRIVER_VERIFIER_DETECTED_VIOLATION (c4) wfplwfs.sys Here is the miniapad: https://1drv.ms/f/s!Aj7SX1fggRNJgQ_o6eExGA8RTO8b
actually, i'd like to write a post about this problem on my blog https://www.bestadvisor.com
