Startup issues - not repaired by sfc /scannow

Hello:

Need help with startup issues that began suddenly on 3/16 - Dell XPS 8100.

3/16:
Out of the blue (no prior shutdown or startup issues) could not boot.
Eventually got into WRE which automatically (?) ran startup repair, but "could not fix".
(I was too freaked to note the details.)
Eventually booted to safe mode.
Ran diagnostics: OK.
Rolled back to system RP from 3/10.
Seemed OK.
Normal shutdown/cold start and normal restarts for ~24 hours.
3/18:
Booted partially to desktop without system tray icons, had mouse, but start menu froze, requiring hard shut down.
Booted to safe mode w/networking.
Disabled all non-MS services and all non-essential startup programs.
Booted fine.
Selectively re-enabled important services; still OK.
Because AVs don't like system restore, even though KIS2011 was working OK, I cleanly uninstalled KIS (& MBAM & SAS), ran their cleaners, and reinstalled all.
Scans with all 3 -- plus ESET online scanner -- are all clean.
No evidence of infection.

3/19:
CHKDSK /f /r: No problems found. System still working fine, but no attempts to reboot.

Today:
SFC /verifyonly: "Found integrity violations"
SFC /scannow: "Found corrupt files but was unable to fix some of them".
Then, for no reason, explorer just crashed.
I did a warm restart (first in 3 days) & it was slow, but went OK.
Not sure about a cold start though -- too scared to try it since last week.

Windows repair install is not an option b/c system is now SP1 and original install DVD is not.

Dell is only offering either a OSRI from the recovery partition or a complete clean install (nuke/pave?). That will cost me weeks of lost productivity (I work mostly from home).

So, it looks as though I am down to this: Extract Files from Windows 7 Installation DVD

But it looks to be very technically complicated.

I do have the original Win7 install DVD, but it is without SP1. So, I'm not sure if the files that Windows tried to repair are even on the install disk.

Can someone please, please review my attached sfc.txt log to see if it is worth trying?
(I also have the xml Reliability Monitor history (wrong file format), a complete CBS log (too big?), if needed.)

PLEASE HELP -- system works fine as long as I don't have to shutdown.
Not a long-term solution, of course.
So, I need to resolve soon.

THANK YOU SO VERY MUCH,

MM

Hi, Greg:

No, no contacts at Technet or MSDN.

Sorry, I am an old, self-taught home user who doesn't really grasp the highly technical stuff.

Are you saying that I can't do the "extract files" thing b/c my install DVD does not contain the files in question and/or that it won't work b/c 7-zip won't have the correct version of Win7?

So, my only options are:
1) Download a current ISO of Win7 that contains SP1, burn that to media and use that for the file extraction?
2) Or do the same and perform a repair install with that disk?

Both seem risky and a "long run for a short slide", with no guarantee of success.

I am really stressed - I don't know which is the best of several apparently bad options: losing so much time and productivity to reinstall the system & everything on it from scratch, or trying a somewhat faster "fix" that might irreversibly break what is otherwise a totally stable, usable system.

Please advise -- in the interim, I'll look at the link you mentioned.

Thanks,

MM

I think you should be able to create a new system repair disk and use that. Use method 2.

System Repair Disc - Create

Then run sfc scan (offline) and startup repair a few times. You can also consider running bootrec commands.

How to use the Bootrec.exe tool in the Windows Recovery Environment to troubleshoot and repair startup issues in Windows

If the disk doesnt work, go the way Greg suggested.

But ultimately, you can just save all your work and run the dell factory restore.

Edit: Edit: If you had created a system repair disk previously, try using that as well.

SFC /SCANNOW : Run in Command Prompt at Boot

Hi, Bill2:

OK, so now I am confused.

I have both the factory install DVD (no SP1), and a repair disk created the day the computer arrived (also no SP1), and there is a recovery partition on the D: drive (factory image, also no SP1) that was used to re-image the OS once back in 8/2010 (thanks to OEM McAfee crapware version update).

I already ran sfc /scannow from the elevated command prompt this morning -- that's what was run to generate the log I attached to my previous post.
Would it not have tried to repair the files from the recovery partition, but it could not?

And startup repair ran the day the problem started -- however, this was prior to doing the roll-back and the other hardware diagnostics, chkdsk, sfc & troubleshooting).

Most of all: I don't understand how creating a new repair disk, now, with a "corrupted" OS (even though it is SP1) solves anything, since the OS in its current state contains corrupted files.

1. So, what should be the next step -- especially based on the data in the sfc.txt log?
A) Run another startup repair?
B) Run sfc /scannow again (I don't know what you mean by "offline")?
C) Bootrec.exe (again, looks hard and risky?)?

2. Am I correct to assume that I can NEITHER do a repair install NOR run the "extract system files" procedure from my Windows install DVD (Extract Files from Windows 7 Installation DVD) b/c both require that the DVD be the same SP or higher, which it is not?

The more layers of tutorials and KB articles I read, the more my head spins.

Thanks for your patience and expertise,

MM

EDIT: Error. Sorry, I guess this link is for instructions how to run SFC "offline".
I had run it, but from within Windows, I guess?

already did that.
thanks, though.

1) Your sfc log showed a corrupted tcpmon.ini, dont think thats contributing to your startup problems.

2) Dont confuse an OEM factory restore disk with a System repair disk. The former are made by using the recovery manager on the computer such as dell's datasafe. These restore the computer to factory state and is identical to restoring from the OEM recovery partition.

A system repair disk that is created via the method I linked in my earlier post merely lets you boot to system recovery options (such as startup repair, command prompt etc.).

What you should do is to create a system repair disk (if you already have, use that), boot from it and run offline sfc scan and startup repair. This is explained in the tut Ted linked. If that doesnt help, try repairing boot via bootrec commands that I linked in my earlier post.

Go one by one and ask after each step.

3) Or you can just reimage from the recovery partition and install SP1 later. For this backup all your work first.

4) Your assumptions about the pre-sp1 dvd are correct.

Hi, again, Bill:

1) So, what do I do about corrupted tcpmon.ini, since I don't even know what it does?

2) OK, thanks for the info. I'm still not sure I understand it all. The original repair disc I created (from the Windows control panel > system protection) dates to the day I received the computer, so it is not SP1. But if I understand correctly, that doesn't matter. Is there any point in creating a new one now (with SP1, but with "corrupted" files)?

3) I am a bit wary of going back to factory image a 2nd time.
Here's why: it was used to reimage Windows 08/2010 successfully after a major update of OEM McAfee corrupted OS drivers. Although it was uneventful & system has been stable (replaced McAfee with KIS2011), I was shocked to see a red, critical event in my newly discovered (by me, just last week) Windows Reliability Monitor console time-stamped for EVERY single shutdown dating back to the day I did the factory image. It looks as though EVERY time I shutdown, Windows said "Windows was not properly shut down" > technical details > "The previous system shutdown at <whatever time> on ‎<whatever date> was unexpected." This has been happening invisibly to me, with NO shutdown or startup errors until last week. I have no idea what this means, but if I go back in WRM console all the way to 8/15/2010, it appears to have generated this message every or nearly every time the system was either restarted or shutdown.

Anyway, fearing some sort of subtle corruption of this factory image, I hate to lose 6 weeks of my life going back to something that may or may not resolve my current issue.

Moreover, I read this: SSD / HDD : Optimize for Windows Reinstallation. It seems to reinforce my reluctance to restore to that image, rather than a CLEAN INSTALL or REFORMAT/REINSTALL.

4. OK. So, those are both non-starters.

5. SOOOOOOOOO, getting back to question of how next to proceed:

OFFLINE SFC /SCANNOW: I read the tutorial, but I am not sure which method to use -- I assume One is OK, since I have both the install disk and a repair disc, and I don't have a dual boot system.

But I don't understand 2 steps, where it asks to specify the drive being repaired and the source of the "repair" files, esp since Brink's example uses the same drive "f:" for both.
The OS drive I am trying to repair is C.
The DVD with the install media will be in an optical drive D: or E:.

Moreover, to do this, I first need to shutdown > tap F2 > change boot options to put CD/DVD first on list > shutdown system > put EITHER install disk OR repair disk in the drive > reboot from tower?

Thanks,

MM
