Windows 7: Cannot get past login screen - have tried everything

Cannot get past login screen - have tried everything

Hi all,

So, the day before I left for the holidays, my Windows 7 auto-updated and I was unable to boot it at all. I returned three days ago, and have spent every single one of these days trying everything I could to fix it. All for naught.

It all seemed to go wrong since an update on December 19th. Since then, when I attempt to log in after startup, I typically get the error message "Could not connect to System Event Notification Service", followed by a black screen.

Occasionally I will get a different message stating: "The application was unable to start correctly (0xc0000022)"

I've done multiple startup repairs, disk checks, yada yada. Initially some errors were found and deleted/fixed. Now no errors can be found.

Yet when I try to a system restore (to the state prior to Dec. 19th) I am told I cannot do a system restore because there are disk errors.

At this point I feel that I have tried just about everything and am now caught in an endless loop of catch 22s about which I can do nothing.

Can anyone suggest a way out of this quagmire so that I can use my computer again? I am posting snapshots of what I have described above for reference. Thank you all in advance!

Did you let it do a disk check on reboot? Can you start in safe mode and get to a cmd prompt to do the disk check or failing that if you have an install disk boot that and run a disk check

Already done multiple disk checks on reboot. Unfortunately I don’t have an install disk...I don’t recall one coming with the computer when I bought it 8 years ago.

Hi benmillerfilm,
Install disks don't come with computer anymore, they have recovery partitions.
Try reverting to Last known good configuration - Windows 7 Help Forums
If that doesn't work, do you have a restore point or preferably a full system image backup?

This is specifically for Vista but it works for 7 as well. Repair Vista Options - Preferred Sequence | Vista Forums I suspect that your hard drive is failing. You should determine which brand of hard drive your have and download the diagnostic tools for your hard drive. Once you burn the diagnostic tools to a disk you will boot into the disk and run all the scans, especially the comprehensive. If it tells you that there are issues work with the vendor to determine if your drive is under warranty and if so replace it. You might also do a back up of all your data to an external drive if you don't have an image. You can use a linux bootable disk such as knoppix or ubuntu to attempt to back up your data.

Windows Vista/ 7/8/8.1 keep a regular backup of the registry handy in case you need to overwrite a corrupted registry. By default, the RegIdleBackup task runs every 10 days, so that’s as far back as you would lose if you replaced the current registry with the automatically backed-up files. You can find the backed-up registry files in \Windows\System32\config\RegBack folder.


Please boot your computer with Windows Setup Media and from Windows Recovery Environment start the Command Prompt.

Please type below command into Command Prompt and press Enter key.

Code:
 Dir C:\Windows\System32\config\RegBack

Above command will list files stored within RegBack folder and there file size, make sure files are not zero size if they are do not follow below instructions.



Please replace partition letter C: with Windows installed partition letter. When computer boots into Windows Recovery Environment (WinRE) environment the drive letter assign to Windows partition may not be C: drive letter because Windows 7, 8 , 8.1 and 10 creates a separate system partition when it's installed from scratch. The system partition contains boot files WinRE assigns the system partition the C: drive letter and the Windows installed partition will be assign any other drive letter usually D: drive letter is assign to Windows installed partition. The Bcdedit /enum | find "osdevice" command can be use to find out the drive letter of the Windows installed partition the output of the Bcdedit command is similar to this osdevice partition=D:. The drive letter after partition= is the drive letter of the Windows partition.

Please type below commands into Command Prompt and for each command you have typed press Enter key.



Code:
Replace C:\Windows\System32\Config\RegBack\*     C:\Windows\System32\Config
As files are replaced, the Command Prompt displays their filenames on the screen.

This procedure assumes that Windows Vista/7/8/8.1 is installed to the C:\ partition. Make sure to replace C:\ drive letter to the appropriate Windows OS installed partition drive letter if it is a different location.


Above commands renames the registry files at their existing location, and then copies the registry files from the RegBack folder to the C:\Windows\System32\Config folder.

Hi townsbg,

Thanks for your reply. I should be clear that I can't access any sort of desktop or startup screen--even in "safe mode" I just end up with a black screen. The best I can do right now is get to the "Command Prompt" screen and type commands. Some of those solutions seem to presume otherwise. I have run multiple disk checks at this point, with no apparent effect on startup.

Hi Freebooter,

Thanks for your response, I am going to try that now from the Command Prompt screen.

Hi Freebooter,

Tried all of that but no change. The initial \regback did something (tried to post a screen shot, but image attachments are not working on SevenForums right now for some reason). The other commands I'm not sure did anything.

Followed it with another check disk, which did find errors and fixed them.

However, upon rebooting, I still get the same error message when trying to login.

Tried to do another system restore, but I still get the same error message (shown in a previous screen shot) telling me it can't do a system restore because there are errors that need to be fixed.

Any other suggestions guys? Is this the end of the line?

You need to back up your data and test the hard drive with the manufacturer's tools.
