How To Repair System Files That Were Corrupted During Update
Sep 15, 2011
My computer was installing the latest updates for windows 7 professional 64 bit and the battery died during the shut down process, and now when I start the computer it will allow me to log in but when it hits the desktop it freezes up completely. I have tried using the system restore but somehow my restore points cant be found anywhere and when I tried using the system repair option on the installation cd it says it cant because the problem is unfixable. The error it says it has is in the boot sector and it says the error code is 0x45d, but when I ran it a second time it didn't say that. I really don't want to deal with pulling off all of my personal files and then installing a fresh copy of windows because that would be too much of a hassle, but if i have to i will.

I have had the generic.win virus on my computer for a while now due to my anti virus program not being able to remove it. It has been causing internet browsing issues specifically with google and other search engines. However I believe that the virus has corrupted my "Windows repair tool" that is required to reformat my system. I start my computer and hold F8 to bring up the menu and select the repair computer option and it brings me to the menu where I can either "start windows normally" or run system repair tool.
When I try to run the system repair tool I know it is supposed to bring me to a menu to select language and what not and ultimately restore my computer. Unfortunately it just returns to the normal boot up and repair option over and over upon selecting the option. I just want a virus free computer. My system is a dell inspirion running 64 bit windows 7. I have backed up all the files.

I have had Win 7 installed for a while now).
Here is a summary of my problem:
1) My computer recently got stuck on the "Starting Windows Screen." So I manually held the power button to reboot.
2) On reboot, it said there was a need to run a startup repair, which I did. Everything checked fine, except for the last one which said "System Volume on Disk is Corrupted," which it claimed to have successfully fixed.
3) After rebooting from repair, the system gets stuck on "Starting Windows Screen" for a good 10-15 minutes, after which it runs a registry check. After it completes that I get hopeful -- but the screen then gets stuck on an all black screen with just the mouse cursor and nothing more.
4) Additional note: Attempting to start the computer on "safe mode" leads safe mode startup to become stalled on "DRIVERSCLASSPNP.SYS"
5) The lastest attempt to repair yielded this message: "Startup repair cannot repair this computer automatically.

I (my wife) is running Windows 7 Home Premium (64). Windows explorer crashes when:
-Searching with more than 4 characters in the start menu
-Opening the Network and Sharing Center
-Various other times that seem unrelated
I have attempted:
-Startup repair X3 : it catches problems but doesn't repair them
-sfc /scannow command : also catches problems, and the CDA log shows all of the corrupted files.
-Copying the system32 files from a fresh windows install to fix the broken dll files while in another os : this didn't seem to have any affect
-System Restore doesn't have any images before the issue began
-Full system antivirus and malware scan and rootkit detection with no results showing (doesn't rule it out, but I used Norton commercial, Mbits, Lavasoft, and Kapersky online all in safemode, and some rootkit detectors)
-Repair Install : hangs when initiated
-Updating windows to SP1 : it seems the system attempted to update some time ago and failed or was interrupted. Now SP1 won't install, the updater hangs
-in an attempt to fix the windows update hanging issue, I tried:
-Installing the system update readiness tool (Download System Update Readiness Tool for Windows 7 for x64-based Systems (KB947821) [September 2012] from Official Microsoft Download Center) : the update hangs too
-Installing the fix it program here (Fix the problem with Microsoft Windows Update that is not working) : didn't make a difference
-renaming the software center file as in this thread (Script or command to delete contents of Software Distribution folder?) and re-attempting to install sp1.
I (my wife) has some very expensive programs on her computer that we no longer have install discs for. She had them before we were married, but they seem to have been "lost in the move." We can probably work with each of the individual programs, but I'd sure like to look at other options that allow her to keep her file and program structure intact.

I've had trouble with my machine starting. I've done all the advice the 7 Forum suggests, running start up 3 times...etc., and it will work for a day or two, then not start. Then if I hit the reset button a couple of times, it will go into the start up repair and I end up with this message:
Repair Action/ System files Integrity check and repair
Result Failed / Error code = 0x490
Time Taken / 700863 ms
I've run sfc from an elevated window and it says everything is fine.

My 3Tb HDD recently started acting up. I use SSDs in a RAID0 to boot with and pretty much everything else, including desktop, downloads, documents, etc. are redirected to the HDD. It started with missing icons for shortcuts and then folders became inaccessible with an error message of "The file directory is corrupted or unreadable." The folders, that contained plenty of files, were reporting 0 content and more folders started to become affected.I restarted my computer hoping it was a temporary glitch but now windows is telling me the drive needs to be formatted. Disk Management reports the drive to be operational with 2794.52 GB RAW and Healthy (Primary Partition). I booted linux from a USB stick and was unable to mount the drive. Kaspersky Rescue Disk simply doesn't recognize the drive. Possibly the oddest thing, though, is that EaseUS Data Recovery software is reporting only about 770GBs for the partition. Whats strange about it is that's right around the amount of free space that was on the drive.
I haven't run a CHKDSK or checked for bad sectors yet because I'm hoping to try to recover the files if possible. I have backups of the important files but there's a huge amount of data that isn't backed up that I'd at least like to try to get to before reformatting or doing something else that will ruin any chance of recovery

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.
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

Every time the computer is turned on or restarted it runs Starup Repair. When i look at the diagnosis it says 'boot critical file c:\ci.dll is corrupt'. I have already tried to restore the computer but i don't have the discs where i have backed up the computer. I have also run a virus scan with Avira and it did pick up 4 viruses and i removed them but the error still occurs.

my computer, a toshiba satellite L655D-S5159, has been broken recently. At first, I got an infinite startup repair loop, because of a corrupted registry. I checked the registry files and they are all 256kb. I tried to run sfc /scannow and chkdsk /f /r, but that didn't do anything. Then I tried to run bootrec rebuildbcd, and now I'm getting error 0xc0000225 at startup.

I installed Driver Utility and it was installing 2 new drivers and a littler earlier there was a Windows update popup and it had to restart so I hit postpone for 4 hours
and so I left it to finish installing the 2 drivers and I checked on it 30 min later and it started restarting and then it showed the specs for the laptop and then it gets to a menu (all black background) and the options are
Launch Startup Repair
which finds no problems
or
Start Windows Normally
which just shows the specs and ends up on this screen
I tried doing a System Restore and it didn't even do anything from that
and I ran a diagnostics and I also got nothing
so does anyone know how to fix this?
this is Windows 7 Ultimate

Created it with no problems, apparently at least. My BIOS is set to boot from CD drive, so why won't my machine boot from the system repair disk? There were no errors when disk was created. My machine just boots to windows.
Anyone else experience this with Win 7 Professional?

I've moved tons of files to an external hard drive [Samsung external USB HD (FAT32)]. After that, I've tried to eject the device in Windows 7, via Safely Remove Hardware but Windows said that the device was in use, even though everything (applications and windows) were closed. I decided to use USB Safely Remove software to eject my portable HD. I really don't know if that was the problem, but since then I found a lot of folders inside my external HD corrupted.
In the corrupted folders, JPG files looks like this. I can't read the other files (PDFs and PSD) in those folders, Adobe Reader and Photoshop says that the file is damaged. I've tried Windows 7 error-checking but the files are still corrupted.

I have a bigger problem now... I had a lot of restarts since a unknown problem appeared (what makes my windows freeze + restart all the time). Beacuse I restart my computer each day when he freezes, i have now problems like files and folders being corrupted and inaccessible. Can't access a folder or open program. It even says that some .exe program is corrupted or web browser too... but i can open 99% of them only not 1 or 2. I think that reinstalling my win is the only way out of these many problems i have now beacuse restarting my computer each day by 2-3 times isn't a solution.

I have 3 corrupt installations of the same OS (Windows 7 U. 64 bit) in the same hard drive. I can't install any OS(es), and my original (working installation) no longer works. These corrupt installations are corrupt because windows installed incorrectly twice they left old windows instead of creating a windows.old file.When I try to start up any of these three installations, I get the same error: "The computer restarted unexpectedly or encountered an unexpected error. Windows installation cannot proceed. To install Windows, click "OK" to restart the computer, and then restart the installation."This also happens upon completion of reinstalling windows.I have tried to wipe the drive:most programs I see need windows to operate...I've tried a few programs that can be booted, DBAN boots, but I get the same error every time: That DBAN has encountered a non-fatal error and that the error is usually caused by damaged disks.

System:
AMD Phenom II x6 t1055

2x4GB Kingston pc3-10600 (1333Mhz), just new installed.

Windows 7 x32 & x64 Ultimate NL Retail
I had some issues after doing what an Anti Virus software asked me to do and register cleaning.Windows looked acting slow and some futures (both still) don't work.I have to mention that I had a bad memory that killed two slots on the main baord.Previously the Windows 7 x32 didn't start completally, it didn't get to the login screen. The mouse pointer was vissable and the screen was black.
I looked on the net for answers, but found non. So, I tried to expermimanted some F8 functions ad the MBR screen. I found one that did work, something for domein users. All the other options didn't work.I got it started (safe mode) and deleted the last month installed software.Did a chkdsk /F and restarted. [URL]I found one site with the command sfc /scannow to check the system files and fix them.After a while (not minutes as it says) I got the notification that not all system files could be fixed.It installed a log file ad WindowsLogCBS about 24MB.How to fix these errors?no reinstallation. I have software that came from GiveawayOfTheDay, the software can only be installed once.Or,After a reinstall, would it be possible to reinstall the software from the Old installation. Actually stupid to do, can have bugs too.
Is there a total Windows 7 x32/x64 repair disk that comes with the programs itseld and can check the net for information and can install and deinstall software for download?I forgot to burn the one that came with Windows 7.I downloaded a Repair disk, but it kept asking for Backup and Command prompt didn't work either.Guess, the DVD program did need those files on the Windows HDD installation too.Autoback up was disabled, don't know how. So, no backup at all. No restore points either.

My hard disk is corrupted and it causes frequent blue screen and restarts. I bought a new hard disk and transferred the data to the new hard disk. While transferring the files from old hard disk to new hard disk, the pc still encounters frequent blue screen and restarts, causing the data transfer to suddenly stop when it restarts.
Now I have installed the new hard disk and everything works fine.
The problem is when I open some word and excel files, the files are blank (like a new document) or show me a error message. This is probably caused due to the sudden restart while I was transferring files. I remembered some of the corrupted files are being transferred when the pc restarts by itself.

Every time I download something from Internet Explorer for like 2 MB or more it turns out to be either corrupted or unfunctional after download.
At first when I download a file the browser scans it and tells me its unsafe and wont open even though I know it isnt because I have used it many times before on my previous computers, but I tried downloading the same file again and it said it was unsafe BUT I was able to run it either way, after downloading that file it seems to bug up at Install in some point, I have no idea what is causing this so I turned my Laptop back to Factory mode but im still having this problem, Tried to turn it back to Factory mode again, still nothing.

I have an Acer Aspire 5734Z with Windows 7 Home Premium 64-bit installed and ever since I got my computer I've been having trouble starting Windows normally. Like many time before, a week ago my computer started again freezing at the Windows logo every time I put it on. Here's what I tried to do to get things back to normal: 1. I ran CHKDSK /r, and got my computer working, Two days later, I had the same problem. So, I ran CHKDSK /r (found 48 unreadable file segments, deleted 60 index entries, corrected and deleted file names..), but it froze at stage 3 of 5, "verifying indexes", and after 19 hours I shut it down. Still having the same freezing problem, I ran CHKDSK /r once again (found 13 bad clusters..) and I noticed the line "Windows has made corrections to the file system". After the check was complete Windows wouldn't still start. I tried all the different Safe Modes, but got stuck at loading "windowssystem32DRIVERSAVGIDSEH.sys" or the file after that.

I probably got overly ambitious with a disk cleanup utility and now several functions of windows 7 don't work. New updates don't install, other updates that I DID install are missing, I am unable to run certain games, and I can't run SFC /scannow.However virus scan updates appear to be fine.What is the best way to fix this? I have an old backup I did with Norton Ghost on disk but something is wrong with the second disk so I can't use to to reinstall the entire backup but I might be able to extract some old files if I knew which ones to extract. I am running Window Seven Home Premium. It is a legal copy. I got it directly from Microsoft. If I try to run SFC /scannow from Windows I cannot get it to show up or do anything. Its like I never did anything. If I try to run SFC /scannow from the boot CD using this command
sfc /scannow /offbootdir=f: /offwindir=f:windows
I get this error messge:
Windows Resource Protection Could not run the repair service IF I try to run the repair outlined here:[URL]I get an error saying Windows cannot find the file specified.My computer specs are
desktop:
Drive C: W7 Home Premium 80GB NTFS (IDE)
Drive D: WinXP Pro sp2 80GB NTFS (IDE)
Drive E : Storage 80gb (IDE)
Drive F and G DVDR's
