Verification of a known DLL failed

Monrng all

Switched on my home computer last night and got the above BSOD error.

I can't remember the error codes (I'm currently at work).

I'm running Windows 7 Home Premium.

What I have tried:-
Letting windows repair itself - same error
Safe mode - this loads but I can't do a great deal with it
Safe mode with networking - get the same error
System Restore - Still getting the error
Restore from backup (disk image) with Acronis - still get the same error

I haven't tried using the Windows disk to affect a repair, does anyone think this is a good idea as I don't want to lose my data?

I'm not sure what else to try (I think I'm going to have to get a new HDD anyway), so I'd appreciate some advice on other options.

Thanks in advance.

an acronis restore should have taken it back to when it was working, assuming that's when you did the backup

run chkdsk c: /F to check the disk out

rmg1

I'll need to do that when I get nack home (I'm currently at work).
The restore was from the 26th of December (my most recent). I did a disk image but not a sector-by-sector image, don't know if that will make a difference.

Can I run the CHKDSK from safe mode? I don't know if safe mode with command prompt works as I haven't tried it.

yes you can, it will do it after a reboot

if the system was working on 26/12, acronis restore should work too - assuming you have gone throught the restore process.

I booted from the Acronis CD and followed the prompts to restore from the backup drive.
Not entirely sure if I did it correctly though. I ticked the box to verify the backup and it seemed to take over an hour to do what it was doing. I'll have another go tonight after I've run the CHKDSK command.

I had this BSOD on one PC and rather than restore from a back-up I wanted to pin down the problem. Eventually found that, out of a recent bunch of a dozen or so MS updates, it was one particular kb security update for IE9.

That was the easy part - getting it to boot in any mode was a nightmare. Using cmd prompt from rescue dvd, ran usual chdsk, sfc, system restore etc but every reboot resulted in same BSOD. It seemed to get stuck in a loop of applying the update (even with system restore updates off), then BSOD'ing.

I then discovered the DSIM tool and managed to get it sorted with this from the rescue dvd cmd line:

DISM /image:C:\ /cleanup-image /revertpendingactions

Edit: After the revert pending actions allowed me to boot I just installed the last batch of updates one by one until I found the culprit. There was a twist to this however - updates that required a restart (i.e. little icon showing in the Start --> Shutdown button) would put me back into the same BSOD loop. I thought about deleting the pending.xml but this put me off.

I then discovered that ctrl-alt-del and using the power button drop down from there allows a choice of shutdown without applying pending updates. It was then a case of DSIM, Sytem Restore, manually apply updates one at a time, shutdown and manually power up by ctrl-alt-del method for each update that required a restart.

Footnote: Eventually pinning down that the problem update was a critical kb security patch for IE9 I couldn't find a way to apply it and not get the DLL verification BSOD. Since I don't use IE I managed to get round that by updating to IE10.

This is mostly answered, but just to note that if safe mode boots then there is no point in going to safe mode with command prompt. This is simply a version of safe mode that loads a bit less stuff in so is more likely to boot but is harder to use.

Thanks for that folks.
I'm going to do the CHKDSK when I get in and see how that goes.
I don't remember allowing any updates to be installed over the last few days which is when it happened.

I'll check though if the CHKDSK command doesn't work.

Hi all

Currently typing this on my phone.
Unfortunately neither chkdsk nor dism worked so I'm reinstalling from scratch. I should be able to access everything from my old documents (according) to the text but I think I'll try the acronis cd again once this has finished.

Linux boot disk, and be certain of recovering your docs etc? I did just this last night for my bro-in-law.

The DISM command only works from the Windows Recovery Environment.
