Hi all,

Attached dump files zipped folder.
I have been experiencing this BSOD 1 time, and the other BSOD (0x1000007E) 2 times.

Any other relevant information I will be gladly able to provide, let me know.

Kindly assist.
Thank you all in advance

This is difficult because driver verifier is blaming something else which isn't the cause, wdf0100.sys to be precise.

Now for testing purposes there are a number of things I'd like you to try,
Can you please remove Avira anti virus just for now.

Secondly what USB devices have you got plugged in as there are a lot of USB drivers unloaded at the time of the crashes.

Unloaded modules:
fffff880`0b143000 fffff880`0b160000   ew_hwusbdev.
fffff880`09f71000 fffff880`09fa2000   WUDFRd.sys
fffff880`09e82000 fffff880`09e9d000   USBSTOR.SYS
fffff880`09e00000 fffff880`09e0f000   modem.sys
fffff880`09e0f000 fffff880`09e82000 <- This module is very suspicious.
fffff880`0b12a000 fffff880`0b143000   LtDevice64.s
fffff880`04593000 fffff880`045b8000   avipbb.sys
fffff880`06023000 fffff880`06045000   avgntflt.sys
fffff880`07c24000 fffff880`07c3c000   avnetflt.sys
fffff880`0b0b2000 fffff880`0b0cb000   LtDevice64.s
fffff880`0b024000 fffff880`0b095000   spsys.sys
fffff880`09fa2000 fffff880`09fbf000   ew_hwusbdev. <- Again it's a driver part of Huawei Technologies
fffff880`09f71000 fffff880`09fa2000
fffff880`0190c000 fffff880`0191a000   crashdmp.sys
fffff880`0191a000 fffff880`01926000   dump_ataport
fffff880`01926000 fffff880`0192f000   dump_atapi.s
fffff880`0192f000 fffff880`01942000   dump_dumpfve
I have a strong suspicion your USB Modem/Serial Device Driver by Huawei Technologies is causing issues.
Please remove it completely.

Thank you so much for responding my thread, I really appreciate it.

So, I have removed the Avira anti virus.
And the USB device that i got plugged in are speaker and that Huawei Modem, and i'll try to remove it completely and change with other USB Modem.

Thank You, if you want other informations don't hesitate to ask me
