[SOLVED] BSOD Win 7 DPC Routine Stop: 0x000000B8

Hello there,
I need your help as Win 7 is giving me BSOD´s out of the blue.
Right now it is running in protected mode after debugging (start up menu F8) and it works just fine (at least so far), so I suspect it is some faulty command or file that is used only when booted up "normally".
As Win7 restarts automatically after a crash, I was able to gather only the following information:
something like faulty DPC routine
Stop: 0x000000B8
0x86983A48
0x86844030
0x93E5AFD0

I have changed the ram-banks already to exclude an error with those, brand new harddrive didn´t do the trick either (probably because I just cloned my existing Win7-partition as I am not too eager to set up my system from scratch :rolleyes: )
The memory.dmp I have is about 230mb, so way to big to have it attached, so I just attached the mini.dmp it created yesterday.

System is Win7 x86, all updates included (and up-to-date), laptop is about 2 years old, it worked just fine until about 2 weeks ago...
If you need further information in order to help me stay sane, please do not hesitate to contact me.

I sure would appreciate any information :pray:
Thx and kind regards,
LittleX

So, please completely uninstall your Acronis True Image which is causing you the grief. :grin:

Re: BSOD Win 7 DPC Routine Stop: 0x000000B8

Acronis???? I had it up an running for ... months without any trouble :rolleyes:
You sure it is True Image and not Acronis Disc Director? This I had installed recently but not used at all so far... But the time frame looks about right, so I will just get rid off it and hope it works out for me.
Thanks for the input and help, I´ll let you know how it goes...:wave:
If you hear any crude words, just ignore them, it will be me damning my computer if it does not work :upset:

Re: BSOD Win 7 DPC Routine Stop: 0x000000B8

Got rid off the Disc Director Suite, so far, so good....
System is up for 10 minutes and counting :smooch:

The snapman.sys is still on it, as you said, it belongs to Acronis True Image, but I like to think that Disc Director and True Image didn´t go well together on the same system :4-thatsba

So, just keep them crossed for me, I really would like to keep True Image, but if Win7 still suffers indigestion, I will delete it as well for my peace of mind :wink:

Thanks again for your immediate reply and help, I would never have thought of this program to be such a pain in the rear...

Re: BSOD Win 7 DPC Routine Stop: 0x000000B8

Hi -

What version of Acronis are you using?

The timestamp on the Acronis driver snapman.sys noted in the BSOD dump -

0x45265dbe, which = Fri Oct 06 09:44:30 2006

It is way too old for Windows 7 x86 RTM system.

Regards. . .

Re: BSOD Win 7 DPC Routine Stop: 0x000000B8

2006??? Oops, that sure is way too old
So definitely something screwed up my system, as I am using the actual version of True Image (I am at work at the moment, so I have to check this out tonight).
But as my system crashed again shortly after posting the last message, I will delete True Image anyway and just give it a shot by installing it anew later...:upset:

Thanks for your assistance, and I will keep you posted.

Have a nice day,
Silke (aka Littlex)

Re: BSOD Win 7 DPC Routine Stop: 0x000000B8

Hello everybody!
It took some efforts to get rid off this darned snapman.sys and the Acronis software, but I finally made it...
So far everything works fine (but my Outlook freezes up on me, I think that´s a different matter :4-dontkno and I will take care of it later), so I want to thank you guys for your help and -obviously - accurate diagnosis.
What I did is I forwarded your replies to our network admin to give him an excellent address if he evers runs in any problems he cannot solve by himself. Doesn´t hurt to know where to look for great and immediate advise :wink:

Thanks again for solving my problems and keeping me sane.

Have a nice evening,
regards,
Silke (aka Littlex)
