hello. i run xp and in trying to boot up, the system shuts down and restarts
again and again. I have tried "last good config," but it makes no difference.
I try to access safe mode, but it won't let me get further than trying - it
too returns me to constant rebooting. i chose 'no reboot on failure,' and
got the following stop error: 0x0000007B (0x79BB528, 0xc0000000034,
0x00000000, 0x00000000)

i ran a scan disk and it revealed no disc problems and i installed the drive
as a slave and ran malware bytes and super antispy - they found nothing. i am
afraid my hd might have contracted a boot-sector virus. i do not know.

any ideas hoe to continue?

thanks.
 
You slaved the drive in another computer and ran MBAM and SAS but didn't
do a virus scan with the anti-virus app??

What was done on the computer just prior to the problem? Did you
install any drivers, updates, hardware, or did you change any settings?
 
prior to the initial problem, i ran mcafee (nothing was found) and shut down
for the night. the next morning i rebooted and got my desktop - everything
seemed normal. i clicked onto a folder and accessed a word doc. when i went
to close it, everything froze - the doc, and visible desktop icons. i waited
for 10 min or so and decided to reboot. when the system restarted it got into
a reboot cycle. i tried to get into safe mode (as i mentioned) but the
rebooting cycle continued.. and here i am.

there was no updated drivers or new devices installed - no change in any
related settings. i will say that prior to this, i was not getting any audio,
but simply changed a setting in the sound and devices - and got my audio
back. this was after i ran the aforementioned apps and before i shut down for
the evening.

any ideas?

After you waited 10 minutes or so and rebooted your frozen system. how
did you reboot?

Power button? Pull the plug? Other?

Does the BSOD screen also say INACCESSABLE_BOOT_DEVICE?

The 0xC000034 is an indication of XP being unable to access the hard
disk or unable to find what it needs, but I'm imagine you will see
some responses with Google links pointing to the places to read about
the message but not how to fix it. Generally the readings will say:

The Stop 0x7B message indicates that Windows XP has lost access to the
system partition or boot volume during the startup process.

Most people don't care what it means, they just need to fix it!

If you still have it in some other system where you can scan the
afflicted drive with MBAM and SAS that will not hurt.

I would then move everything in the original hardware configuration
and fix it there.

Boot your afflicted system with Recovery Console using either a
genuine bootable XP installation CD or a bootable Recovery Console
CD. This is not the same as any system recovery CDs that may have
come with your system. If you do not have a genuine bootable XP
installation CD, create a Recovery Console CD.

You can create a bootable XP Recovery Console CD when no XP media is
available:

After you boot into the Recovery Console, for each of your hard disks,
you should then run:

chkdsk /r

For example, from the Recovery Console prompt, enter:

chkdsk c: /r

Let chkdsk finish and correct any problems it might find. It may take
a long time to complete or appear to be 'stuck'. Be patient. If the
HDD light is still flashing, it is doing something. Keep an eye on
the percentage amount to be sure it is still making progress.

Remove the CD and type 'exit' to leave the RC and restart the
computer.

Then we can continue.
 
An 0x7b error during startup means that Windows lost access to the
system partition, the second parameter (0xc0000034) usually indicates
that that the controller driver is missing or corrupt. You can try
booting to the Recovery Console and run a Chkdsk on the drive and see if
things change.

If chkdsk fails to fix things you can try to replace the driver by
copying it from the WINDOWS\system32\dllcache folder to the
WINDOWS\system32\drivers folder. Which driver is it? Well, that is the
$64,000 question. You're looking for a .sys file (a driver), for all
it's worth it won't hurt anything to copy all the .sys files from the
dllcache to the drivers folder.

As the other respondents have already stated, you should run chkdsk with
the /r switch, from Recovery Console, once you have the drive back in
the original computer.

My only other comment is that you ran your virus scan prior to the
problem, from within Windows. I would run a virus scan of the drive
while it is slaved in the other computer, now.....that will help ensure
any virus or rootkit can be detected, while the affected drive is not
the boot drive.
 
boot looping can sometimes
be resolved by running the
command at the disk prompt:

fixboot.

John,

I decided to start with the most simplest of your suggestions ("...replace
the driver by copying it from the WINDOWS\system32\dllcache folder to the
WINDOWS\system32\drivers folder.")

And I must say that this worked. I copied the file from another xp install
on another drive and pasted it on the problem drive - and my original desktop
appeared once I reconnected the drive. however it seems that the ATI drivers
my system utilizes were not found. so my dt looked like it was in some sort
of safe mode. but i re-installed those drivers and everything was pretty much
back to normal.

But now I have no internet connectivity. running an ie diagnosis the error
indicates that the "winsock catalog needs a reset." i found a fix, but it had
no effect.

I might need to post another thread for this issue, but i thought i would
mention it. But thank you for the initial suggestion - at least i have access
to my docs/files/mp3s.

thanks for your suggestion, but John John - MVP offered a solution. you can
read about it if you wish.

thanks.
