    How to repair corrupted dlls and Registry?


    Got a BSOD with STOP error C00021a. Unplugged all peripherals except mouse and KB. Ran an sfc scan, but not all file corruptions could be repaired. Looked at the cbs.log. Three entries keep repeating, but I cannot find the files to replace them with the original ones from the CAB folder on the installation disc.

    ps1xml exists in several places in the Registry.
    The value is Microsoft.PowerShellXMLData.1. No idea what to do about it.

    My knowledge as to what else can be done stops here.

    I would appreciate any help.

    The “offenders” are as follows:

    2010-09-05 23:18:25, Info CSI 000001b6 [SR] Cannot repair member file [l:44{22}]"Registry.format.ps1xml" of Microsoft-Windows-PowerShell, Version = 6.1.7600.16385, pA = PROCESSOR_ARCHITECTURE_INTEL (0), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch

    2010-09-05 23:16:51, Info CSI 00000155 [SR] Cannot repair member file [l:24{12}]"NBMapTIP.dll" of Microsoft-Windows-TabletPC-Journal, Version = 6.1.7600.16385, pA = PROCESSOR_ARCHITECTURE_INTEL (0), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, file is missing

    2010-09-05 23:15:54, Info CSI 00000119 [SR] Cannot repair member file [l:18{9}]"pnpui.dll" of Microsoft-Windows-PnpUi, Version = 6.1.7600.16385, pA = PROCESSOR_ARCHITECTURE_INTEL (0), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName neutral, PublicKey neutral in the store, hash mismatch


    TIA

    I would go with a system restore. I think that is may solve your problems. Just make sure that you go back far enough.

    System Restore
    Unfortunately that wouldn't work for me. I have had this issue for almost a year now. I can't go back far enough.

    I have run a Startup Repair three times. The issue remains. :-(

    Thanks for the input, tho'.

    You'd want a Repair Install instead of Startup Repair - they're commonly confused.

    But first I'd try SFC /SCANNOW Command - System File Checker

    No. I did everything that needed to be done BEFORE I posted here. If I could find the file and the path I could takedown the corrupted files and replace them with the originals, but a search doesn't find them. All files are unhidden, including system files. Also, don't know what to do about the registry key.

    What harddisk model is the system on? Have you checked (if enabled) the self monitoring status? Use S.M.A.R.T. Assistant (free).

    I ask because of your two Hash Mismatches and missing file (typically deleted during offline HD error scans). If disks have had high temps over time, incremental read errors or both usually, irradic behavior should be expected.

    If that's not the case, it should also be possible to plug it into another W7 computer and try "sfc /offbootdir=x:\ /offwindir=x:\windows /scannow" ... never tried this, but it should be a possibility.
