BSOD in pcw.sys - stop error 7e

Hi All,

I recently had the use of a new i7 Computer for one week and was helping a friend to set it up.
Naturally, I had to give it back to him :-(

I get no errors in the build logs. All the Win7PE_SE DVD's and bootable USB's boot and run perfectly on my own Core2 Duo, Core2 Quad and two other laptops, just not on his i7.  I have also tested the same Win7PE_SE builds on other friends i7 laptops and they all work perfectly there.

I tried many Win7PE_SE builds and all ended at a BSOD with stop error 7e in pcw.sys.  This BSOD occurred at the very end of the boot process.  The desktop was fully drawn up, PeNetwork run and fully loaded, all hardware seemed to have been detected, Hard Drive activity dropped to almost zero.

Then the BSOD happened.
I have run memory testing diagnostics in Windows 7.
Has anyone seen or experienced this sort of problem before..?

I am using Windows 7 Ult SP1 as source and x86 build with WinBuilder 082 and using the latest config scripts.

Any ideas as to what to look for in future would be appreciated.  Unfortunately, due the the remote area my friend lives in, I do not have regular access to his computer for further experiments.  And he is very loath to loan it to me, particularly as it has been working so well for the last month.

He is running Windows 7 Ultimate x64 SP1 and it runs very well.

TIA,

Just to update with current info regarding the BSOD 7e on the Gigabyte Z77 chipset i7 board..

The owner of the system brought it back because he stuffed something up and wanted me to fix it for him (and I did).

I have never been able to determine what the cause of the issue was - but it is now fixed.

I have made so many changes, updated scripts from the server, added new DriverPacks tweaked, pushed, prodded, prayed to the gods of the holy electron.   

But something I did has made a huge positive change and the Win7PE_SE now boots and works well.

I just wish I knew what was the actual cause of the original problem and why Win7PE_SE produced a stop error on only that particular system and no other, if only so it might have helped someone else in future.

Hi BobxT,

Sometimes mystery happens,
on most cases either reports helps to figure out what is going on , or reports says it is fixed mysteriously ....

recently we had a similar mystery around here
http://theoven.org/index.php?topic=318.0
which was fixed as similar way you wrote....

as you know there are too many factors,
+ how you make your build (options, additions etc. -> uncountable ;) )
+ the hardware of end users (infinitive :>)

And sometimes you (as an end user) do not have time to figure out "the" factor, hence we can not make required enhanchments.


This is only life   

I am glad your problem solved in one way or another   
With such disk-driver issues, also test with Gena since both Win7PESE and Gena use different drivers, it may help to figure out 

See you

Thanks Lancelot,

I recently migrated from LiveXP to my first few builds with Gena. Like Win7PE_Se, Gena also works on this computer.

Previously LiveXP did not work but Gena does.  Go figure. 

Anyway, I am happy it all works.

hehe, no surprise,
as I previously mentioned at Reply #1 here

with reasons behind here Reply 11 http://theoven.org/index.php?topic=332.msg5470#msg5470 (ChrisR suspension comments),
livexp is death project (last updated 2010-09-08 by us before we were suspended),
Galapo and I left it behind as solid as we can with the knowledges we had that time,
which make it still "look" work ok, but having lots of bugs it has we noticed later when developing Gena and lots of missing updates.....

Anyway, I am happy it all works.

That is the goal  behind the creation of theoven.org , to share all projects we work run happly  ,
it is nice to hear good results from end users 

See you

Hi BobxT!

Such an error usually gives the controller USB3.0 (Intel)

Need to change the driver USB3.0 to another, or even removed from the assembly.
