Hello, I am having a problem where my windows 7 laptop hasn't gotten past the start up screen for over 20 minutes. I've powered off my laptop and attempted a startup repair 3 times with no improvement. When the startup repair completed, the diagnosis showed that the only repair action that failed was System Files Integrity Check and Repair with the error code: 0x490. I've also attempted restore my system up to 3 days ago however the problem persists. I'm currently lost as to what to do and any help would be appreciated!


EDIT: I forgot to mention that any further attempts at using the Startup Repair I get a message saying "Startup Repair cannot repair this computer automatically". It then provides the following problem signature:

Problem Signature:

Problem Event Name: StartupRepairOffline
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: 21200100
Problem Signature 05: Autofailover
Problem Signature 06: 4
Problem Signature 07: NoRootCause
OS Version: 6.1.7601.2.1.0.256.1
Locale ID: 1033

Once I restarted windows, it now sometimes shuts off by itself after a few minutes.

 

 

EDIT2: I've managed to successfully boot into Safe Mode with Networking and opened up the elevated command prompt. I then ran the system files checker SFC /scannow hoping it would fix any of my startup issues. However at the end of it I got a message saying, "Windows Resource Protection found corrupt files but was unable to fix some of them" and left the file sfcdetails.txt of what went wrong. The only error I noticed regarded the file "ksuser.dll."

There's not many experts at fixing Windows Updates (this also applies to SFC.EXE errors).
I am not one of them.
But the few experts that there are a sorely overworked - so getting a reply will be difficult.
I'll continue to attempt to help here, but please bear with me.


First, please try the Windows Update troubleshooter/fixes listed here:
Windows Update Troubleshooter:  https://support.microsoft.com/en-us/gp/windows-update-issues/en-us
Windows Update Troubleshooter KB article:  https://support.microsoft.com/en-us/kb/2714434
Reset Windows Update Components KB article:  https://support.microsoft.com/en-us/kb/971058

Then, if that doesn't fix the Windows Update problem, please do the following 2 things. (copied from here:  http://www.sysnative.com/forums/windows-update/4736-windows-update-forum-posting-instructions.html ):

Run SFCFix

    This free tool of neimiro's creation (see above link) is a very good starting point for the diagnosis and repair of all Windows Update and System File Checker corruptions. We therefore need you to run this tool prior to collecting logfiles.

        -  First download and run a copy of the tool from http://www.sysnative.com/niemiro/apps/SFCFix.exe.
        -  Work through any on-screen prompts and then await completion (runtime is approximately 15 minutes).
        -  Once it has finished, if there are any unrepaired corruptions (the tool will notify you if it has succeeded in repairing all corruptions if they're simple in which case we're no longer needed) or unresolved problems with your computer, you need to post us the complete logfile which opens on exit. Simply copy (Ctrl-A, Ctrl-C) and paste (Ctrl-V) the entire logfile into your new thread (also know as a 'topic'). How to create a new thread is shown later on in this post.

Export CBS folder

        -  On Windows 8, press the Windows key, type This PC, and press Enter.
        -  On Windows Vista/7, click the Start button StartButton_16x16.gif then click Computer.
        -  Double-click on the C: drive, under the Hard Disk Drives category, and then scroll down to, and double click on the Windows folder.
        -  Find and double click on the Logs folder.
        -  Right-click on the CBS folder, and select Copy.
        -  Go back to your Desktop, right-click on it, and select Paste. You should now see a copy of the CBS folder appear on your Desktop called CBS.
        -  Right-click on this new folder, and navigate through Send to, and select Compressed (zipped) folder.
        -  A new file, also called CBS (CBS.zip), but this time with a different icon, will be created.


As for the first item (SFCFix), just copy and paste into your post as indicated.
For the second item (CBS log), please zip it up and upload it with your next post.
If it's too big to upload (or you get an error), just upload it to a free file hosting service (such as OneDrive or DropBox).  Ensure that it's shared and then post a link to it here.
My browser caused a flood of traffic, sio my IP address was banned. Hope to fix it soon. Will get back to posting as soon as Im able.

I have the Knack. **  If I haven't replied in 48 hours, please send me a message. My eye problems have recently increased and I'm having difficult reading posts.
