Phantom USB causing kernel mode bsod

That error was an 0x7f (UNEXPECTED_KERNEL_MODE_TRAP).

Can you provide the memory.dmp file from that crash?

 

Windows 10

Why do I get the message unexpected_kernel_mode_trap and how can I fix it?

 

Counterfit installation:

Troubleshooting a counterfeit installation is useless as it is not known what has been modified on your system.

A counterfeit installation may contain modified code which causes the system to behave in unexpected ways.
For this reason, analyzing counterfeit systems is unreliable and most analysts won't try it.

Please install a genuine copy of Windows and activate it.

If, after you have installed a genuine copy of Windows, you still get BSOD's we'll be happy to assist you.

ok i buyed e activated my Windows with original key and new dump files come

 

Thank you.

The dump from the 29th may give us a clue:

Code: UNEXPECTED_KERNEL_MODE_TRAP (7f) This means a trap occurred in kernel mode, and it's a trap of a kind that the kernel isn't allowed to have/catch (bound trap) or that is always instant death (double fault). The first number in the bugcheck params is the number of the trap (8 = double fault, etc) Consult an Intel x86 family manual to learn more about what these traps are. . Arguments: Arg1: 0000000000000008, EXCEPTION_DOUBLE_FAULT Arg2: ffffd00026376a30 Arg3: ffffd000203f6020 Arg4: fffff83e87f67985[/quote] I'd like you to run a CPU stress test and if that doesn't indicate any errors, Driver Verifier:

Follow this tutorial to stress test your CPU:

Run Driver Verifier:

If neither shows an error then test your RAM:

 

02 oh and 50 min uptime now with driver verifier and no bsod at all -_- ... cpu stress no trouble . waiting for bsod

 

finally i got bsod with verifier on , thanks

 

Dump wasa caused by WmBEnum.sys.

The driver is very old and needs to be updated or removed:
Code: 2: kd> lmvm WmBEnum start end module name fffff801`86b80000 fffff801`86b84d00 WmBEnum T (no symbols) Loaded symbol image file: WmBEnum.sys Image path: \SystemRoot\system32\drivers\WmBEnum.sys Image name: WmBEnum.sys Timestamp: Tue Apr 27 16:10:19 2010 (4BD744AB) CheckSum: 0000E6B8 ImageSize: 00004D00 Translations: 0000.04b0 0000.04e4 0409.04b0 0409.04e4[/quote]

 

i will remove it in the evening , my question is why i have this driver on my system ? i have logitech webcam and also driving gt force ,

 

ok i found and removed Logitech Gaming Software was installed for logitech driving force ,

 

how can i delete all trace of the driver?

 

I would hope uninstalling Logitech Gaming Software would do that for you.I normally use Revo Uninstaller Pro to uninstall software as it does a good job of cleaning up the leftover stuf. To late now though.

 

ok no more bsod now , but now sometimes :

1) after go in sleep mode , no wake up just black screen , and the only way is power off from button
or
2) totally freeze with cursor freezed and the only way is power off from button.

this random without any bsod or error in the log event

 

Try running Driver Verifier again, see if it shows any other problem.

You could also stop using sleep. Instead use Screen Saver to turn off the display and hard drive after a set time.
