Virus Corrupted System Files Cannot Boot
May 22, 2008
I had a problem on booting which is caused by a virus which had corrupted some of the system files. All my efforts to get the system restore had failed. How do I get into the system to go to system restore points. All my efforts to choose all the alternatives in the screen such as safe boot, last known good configuration etc failed. It goes on a cyclic mode again and again coming to the same screen.In such a condition how to go to my system restore point to choose the earlier restore point.

i partitioned the drive when i first installed win xp. C: was already win98se and i thot i'd keep it around a while just in case., i
had the dual boot workin' fine. but whenever i checked in on ol' win98 i got the error message about...whatever. i didnt care cause i never did have a case wher i needed it. so i just always booted to the winxp, which was the second partitioned, named E: and i figuerd one day i would just lose that win98 and make the whole drive winxp. the occassion arose when E: winxp wouldnt boot, error: corrupted system file. it seemed like a "good day to die" so i loaded win xp (pro) into that first partition, C:,and it just fit but with little room to spare. in fact,not enough to do anything, including loading antivirus. i acn still read everything on the E: logical partition, but i dont get to boot from there. i have a couple big eexternal HDD's oneon that machine, the desktype machine (250GB) and one on the laptop (400GB) which runs win xp. i can resort to moving things around, probably having to re-install a lot, but i have tried re-sizing the C: and E:,using Partition Magic (8.0) to no avail. it makes no changes. i've tried enlarging C: to use up the unused space in E:. when i re-boot,nothing has changed. tried merging the partitions, error is differnt cluster sizes, one is 2k, the other 4k. have tried to change the cluster sizes both ways. still no change.

I'm running Windows 2000 Professional, and encounter the problem: "The file hal.dll is missing, please replace it or reinstall it". That shows up when i try to boot it up.When restarted, it looks like its about to load windows 2000, then it stops and says"The file Hal.dll is missing or corrupted,please reinstall to replace it" . I wanted to go to safe mode, but it wont load because of that corrupted file.

I resently downloaded and tryed to install the Rise of Legends demo. during installation it would give me this error:Extracting to "Gocuments and Settings XXXXLocal SettingsTemp" Use Path: no Overlay Files: yes Extracting Rise_of_Legends_Demo.exe bad CRC 9e1b633a (should be a0137306)During installation i get:Setup failed to extract files from F:Cab2.CAB. This is most likely caused by low memory (low disk space for swapping file) or a corrupted cabinet file. Please restart your machine and run setup again.

I am havinga very big problem with my PC. When I try to start it up normally, I get the following message; "Windows could not start because the following fileis missing or corrupt: WINDOWSSYSTEM32CONFIGSYSTEM. You can attempt to repair this file by starting Windows Setup using the original Setup CD-ROM. Select 'r' at the first screen to start repair" When I try this, it opens repair console, but then I have to select OS, and when I do this, it just comes up with the previous error. If I try to reinstall it comes up with a blue screen error and crashes.

We have a Dell Inspiron 6000, and it won't boot Windows XP, giving me the message system32configsystem is missing or corrupt. I've gone through a number of steps to recover, including using Windows XP startup disk to go into Recovery console, following MS knowledge base articles, running chkdsk, etc. What I've found out is that the "system" file from both windowssystem32config and from windows epair is gone.

As my system is running very slow, I decided to look for the source of the problem. While looking at the system information details I noticed five processes under the name "svchost.exe" with the label "not available for all the information tabs (Path, Min working set, max working set, version, size) The same problem with a process called wmiprvse.exe. Please can you tell what is that and if this is a virus, worm or malware or is only a system process?
I have other for processes "svchost.exe" with the path determined "C:windowssystem 32svchost.exe. Is there any difference? I scaned my computer several time just yesterday.

My norton anti-virus said that some files were mssing. It said that if I restored my computer to an earlier date that this should correct the problem. My computer has restore dates so I picked one from the previous day. When my computer re-boted it said that it was not able to restore to an earlier date because some files maybe corrupted. Said to restate the computer and trying restoring again. I did but had same results. Any restore date I pick, it says it is unable to restore.

I cloned a hard drive which had Windows XP on it (the hard drive was going
out) and the new hard drive would not boot unless I booted first to a floippy with boot.ini, ntldr, and ntdetect.com. Have tried recovery console and everything else I can think of, but the system WILL NOT boot to the hard drive. I checked the boot.ini file for improper boot, but everything looks The old hard drive had two partitions on it, but the hidden partition was corrupt so I deleted it. I changed the boot.ini file settings accordingly.

I had tried to run a friends HD as a slave drive with mine on my other machine earlier. I got it up and running & it repaired the friends drive and I was able to get some files off he wanted. After I turned it off & took his out I got an error message that some files are missing in windowssystem32configsystem on my computer that I was using with his HD. The message goes on to say to boot with the windows xp disk and try a system repair. Well, that failed also. I took it out and brought it up here and put it on with this one as the slave drive and I got into it. Is there a way I can repair those files with it running as a slave drive on this one, or do I have to just re-install windows again.

my internet went down soon before this happened, im not sure if this has anything at all to do with this problem, though. our contract with SBC was over so we decided to cancel and sign back up to get 12.99 a month...my friend gave me a zip with these MSN messanger things in it, its just supposed to be these cool random stuff, nothing important i tihnk. a day after our internet service was gone, i tried to extract it, and during the extraction process, some of the files were reported as corrupted, but i let it conitinue to run, and then my computer just restarted on me and now im having all these problems

A while back something weird happened with one of my hard drives that corrupted a bunch of music vids... about 3 gigs worth. The files are still there, but they are unreadable and won't delete. It keeps saying 'file not found' whenever I try and do something with them.

I think I have a corrupted OS in my hands. My computer worked fine yesterday. This morning I added an extended SATA hard drive. When it booted, Windows XP (Pro SP2) startup seemed unusually slow. After I used the hard drive manufacturer's CD to partition the HD and rebooting, I could not get on any of the limited XP accounts because it required a password when it should not have. I am posting this from Firefox, which with a number of other programs unrelated to Microsoft seem to work for the moment. I think I'm missing system files or they are corrupt. I've recently had a Vundo infection which I did clean up, but now I can't even open Malwarebytes Anti-Malware.This would be extremely horrifying had I not had past computer problems of equal horror. I beseech all you benevolent souls reading this to provide some suggestions. Is there anything I could do aside from reinstalling XP?

Since January my computer started getting error messages about corrupted files, corrupted registry, and drivers stopped working. I tried different things and ended up formatting my hard drive and reinstalling Windows. Things were fine for a while, but after a week I started getting messages about corrupt files again, having issues with drivers, and now Windows won't shut down properly. Also, the computer powers off of its own accord sometimes. I'm using Windows XP Home Edition SP3. I haven't made any hardware updates recently.
Some of the error messages I've been receiving are. For Bluesoleil (which I have uninstalled and reinstalled) it says that the file is corrupt and to try an anti-virus scan (I tried to copy the message, but the window went off on its own). AVG anti-virus keeps on saying there are no active components, or replacing all the commands with things beginning with @. The drivers for my Logitech Fusion webcam stopped working, but I've reinstalled them, and they work, for now. The Microsoft Kernel Wave Audio Mixer kept on corrupting. I've also had the message 'Windows - Registry Recovery One of the files containing the system's Registry data had to be recovered by use of a log or alternative copy.

how would you determine if you're MBR is corrupted? Here is the situation: The user boots up his Windows XP Pro SP2 machine, it does the normal POST and gets to the splash screen, however, it seems after that it will display a standard "Microsoft Apologizes but Windows did not boot properly... please select from one of the options..."
When this comes up, we attempt to launch windows into Safe Mode. It runs displays the some messages (more on the lines of what seems to be in the autoexec.bat file) but suddenly the PC reboots. It does the POST again and then the splash screen then bam same message as above. So we try the Last Known Good Configuration option but it does the same thing. Reboots the PC and gets to that screen.

what I do regularly is simple backups of these files to external hard drive and DVD+RW's every x months. My point is that I don't keep different series of backups; I just keep overwriting my external drive and DVD's with the current backup, just to have the security of having a double of my data in a different geographic location in case of fire, flood, theft, etc. (knock on wood)
It occurs to me, however, that this system may not be entirely secure. What happens if, between the last backup and the current one, files on my system are modified in a way I didn't want? Or if someone else uses my computer and deletes files? Or if a file were accidentaly deleted, or even corrupted? In any of these cases, when I'd go do a backup, I'd be backing up a snapshot of My Documents that I don't quite want, because, unbeknownst to me, some of the files are corrupted or deleted, and it's not like I can go back in time and pull out a previous backup from (say) 2002 to recover a lost or damaged file. (The reason I won't keep previous backups is because I don't want to end up with an ever-expanding collection of dozens, and then hundreds of disks to keep in storage somewhere ... and even if I did, how would I know that the oldest DVD's in that pile weren't corroding and becoming unreadable over time...)
So what I want is this: a backup program, or separate application I'd run before the backup, which, when I come to do a backup, remembers the files from the last backup, and somehow compares the last backup to my current system (i.e. compares the previously backed-up files to what I'm about to backup), and tells me, before I proceed to overwrite the last backup with the current one, what has changed, in terms of which files are new since last time (obviously there will be new ones ... pictures, mp3's, docs), which ones are no longer there or corrupted (at which point I can make sure that the absent ones have intentionally been deleted since the last backup, and, if not, I can pull them back out of the previous backup and put them back on my system), before proceeding with the overwriting backup.
I looked at the different typical options, like incremental and differential backup, but they all involve constantly adding the new or modified files to an older initial backup, which always increases the number of discs you end up with. Also, those options will always keep the initial full backup on an old disc that's busy rotting away in the humidity. The way I'm talking about makes you always refresh your backup medium, and if your discs are no longer good, then you just replace them. In short, you would always have a fresh, full backup, and are sure that you're not copying corrupted files or that you're missing any, never to retrieve them again, because it tells you what the problems are before you proceed.
You see, normally, an incremental backup would be what I need, because it keeps an original version of the file, and then it keeps all incremental changes to that file over time, such as modifications. The problem with the incremental backup, however, is the principle that you're always needing more and more space to keep updating the original backup. If I'm backup up to DVD's, I don't want to have a new disc every time I incrementally backup my files. Also, how do you know that the original (1st) base backup, made years ago, doesn't now contain files that have become corrupted? Or the same for some of the earlier increments? Furthermore, there's the problem where, if you need to retrieve a file, you'd have to go back to the beginning, retrieve the original version, and then retrieve all the modifications across all the increments to get back to the version you want to get.
The way I'm talking about would be a rewrite your backup onto the medium (external drive, DVD's, solid state, whatever) every time you backup. That way, you always have a "fresh" set, and are not relying on an original base backup from 14 years ago + monthly increments, and don't have to worry about the original base backup itself having become corrupt after all these years.
Also, an incremental backup won't tell you what's missing or what's corrupt. Let's say you have your My Pictures. One of the folders is pictures from a Florida trip 5 years ago, and in it is a picture of when you had just caught a shark while fishing. That's a pretty important picture, and you want to keep it for all time. Well, meanwhile, you go on 20 more trips since that time, with 20 more folders full of pictures. 5 years later, you don't notice it, because you don't review old pictures very often, but that shark picture has become corrupt and irretrievable in your computer. Or, while viewing the pics from that trip one day, you accidentally delete it and don't notice. Or your friend or family member (for instance, a child) goes through your photos and starts deleting pictures. Or what if they open the picture in MS Paint and vandalise it by drawing a male member on your forehead. Now you come to do your backup of your whole My Pictures. If you simply overwrite the last backup with the current one, you're replacing a good copy of the shark picture with (potentially) a bad one ... or if it's been deleted, you're replacing the folder that had that picture with a folder that's missing it, and you'll never retrieve it again. If, on the other hand, you do incremental backups, then your picture is probably in the original base backup from 5 years ago, or else it's in one of the increments from 5 years ago, but who knows what the state is of the original base backup? Those original discs might be unreadable by now, and then there's the whole hassle of going up through the chain to get the pic. Not to mention that under this scenario, you have to notice yourself that a file is missing, and then take steps to retrieve it, as opposed to an application simply scanning and telling you so whenever you want.
Instead, there MUST be a way to do the full backup each time you back up (so you only have 1 set of discs to go into to find your files, and so that it's always relatively new, and not a rotten, corroded set of DVD's from 14 years ago), and that, before it actually does the backup, it tells you first what's missing, modified, added, corrupt between what you had the last time in your backup, and what you're about to overwrite it with now in your current backup.
I understand that the difficulty in indentifying corrupt files of any kind is that there are many different file types, and no program is so complete as to do that scan. But I guess I'm essentially worried about pictures, since mp3's and documents are less of a problem for me.
So really all I need is any application (not necessarily the backup program) to scan particular folders on my drive (only those I want to back up ... essentially My Documents, and not the whole drive) to check only 3 things:
1) which files have been modified (regular Windows xp search can do this if you advanced search for "files modified between ____ and _____", the 2 given dates being, say, the date of my last backup and the date of the current one);
2) which files are missing since the last backup (all this would involve is checking the files against a list ... seems simple ... and manually looking in Recycle Bin is obviously not enough because you may have emptied the Recycle Bin since last time); and
3) which files are corrupted
With the knowledge of these 3 things, I can take action to replace lost or corrupted files by taking them back out of my last backup. Then, I can safely proceed with the current backup.
I'm running XP MCE 2005.

First I attempted to install Win XP Home from a cdrom to my C partition (20 gigs, partitioned from either my 120 or 160 gig (forget which) hard drive). However it kept botching up and giving me messages about files not copying properly or being corrupted etc. I cycled through a variety of XP install cds (son's, wife's, etc) without any luck. I tried using either the CDRW or DVD drive, in case one might have been faulty...no luck, however.I figured all of this business probably gunked up the works on my C partition, so I thought I'd better format it and wipe it clean, which I did using a Win98 SE boot CD and loading FDISK. I wanted to partition the 20 gig into 2 x 10 gig so that I could limit the C partition to pretty much only Win XP. Silly me...! Turned out I made a 2 MB partition with the remainder of the partition seemingly unavailable to me...couldn't see it when attempting to view partition information.
