Black screen at start up, can't access drives

[pantabulosin]

Hi. I tried reading the forums, but I didn't quite get information on the exact problem I have. When I boot (I use Windows 7 Home Premium 64 bits) I initially got an error message that said I needed the .NET Framework version 2.05 or above in order to use a program called Soluto, I click accept and the computer takes me to the user logon screen. After I enter my password I get a black screen, so I started troubleshooting.

I first tried running on safe mode, and I got the black screen again, so I tried ctrl-alt-del to see if I could open the task manager. I was successful. From there I managed to run explorer.exe as a new task.

At this point I can see all my files using the search bar on the start menu by writing their addresses (as in d:/randomfolder/example.jpg) but I can't open them by clicking on them, nor can I run any application that is pinned to the task bar by clicking on them because I get different errors (such as visual c++ runtime error r6034 and a comment saying something along the lines of "incompatible shell") and I get mixed results from the task manager. However, I can open regedit.exe from the task manager, although I did not use it at all. All of this happens even after I tried a clean boot

I know the hard drive works because I dual boot Ubuntu 10.04 on this machine and I can open the files on my C: drive from there. So I just decided to copy every file in the drive and try other options.

My fist choice was to go to a restore point using the tools in my laptop, but my computer couldn't find any, I then tried to use my backup partition to wipe the C: drive and reinstall windows 7 with factory settings, and the computer couldn't find the drive.

I'm at a loss as to what the problem could be exactly, and I'm not knowledgeable enough to try to solve the problem via the task manager/registry editor. I would appreciate any help that would lead to having windows 7 running as intended. Right now my best guess would be to back up every partition in my hard drive, then wipe everything out and start from scratch, but there must be a better way. Any thoughts?

Thanks in advance.


Update: I managed to open firefox through the task manager and I can browse the web with it, but when I try to download anything it gets cancelled. I tried downloding the executable on the BSOD thread, but I don't even have the option to run it

From task manager try running control.exe and using that to create a new user account. Use task manager to log out and then login as the new user.

Thank you for replying. I tried what you said and I got the following error message:

::{26EE0668-A00A-44D7-9371-BEB064C98683}\0

Interfaz no compatible


that second bit means something like "incompatible interface" in spanish.

I should add that I tried to log on as a guest earlier and I basically got kicked out of the session and sent back to the login screen.

Explorer CLSIDs are unregistered for your account. Try running LUSRMGR.MSC to create the new user.

 

[pantabulosin]

tried LUSRMGR.MSC

Thanks again. I tried it and my computer tells me that I can't use "users and local users" because "I'm not running windows 7 home Premium", and instead it implies that I may be using Windows Personal. However, it does let me go file->options->free disk space. The about section of the Microsoft Management Console shows a Windows 7 Home Premium logo

Thankfully there are still other ways to do this. Try running cmd.exe from task manager and executing these commands replacing "name" with the username you wish to use:

net user name /add
net localgroup administrators name /add

Once again, thank you for your help. I tried your advice and got the following:

net user hola /add worked

net localgroup administrators hola /add yielded system error 1376

That's telling you that the administrators group does not exist! Perhaps it's been renamed by whatever terrible software has caused all this damage. You can list the groups with this command and try to determine which as the administrators group:

net localgroup

net localgroup

Ok, I wrote that command and I got (roughly translated)

Alias for\\myname-VAIO

___________________________....

*Administrators (it actually says Administradores, and it's what I should have written. Language barriers....)
*HomeUsers
*IIS_IUSRS
*Guests
*Event Registry Readers
*Users
*distributed COM Users
*System monitor users
*Performance registry users
The command has been completed correctly

So I tried running net localgroup Administradores hola /add and the command works, and when I try to log on with the new username I get a blue screen (kind of like the old school windows desktops). I didn't log out of this session if that's of any use

I want to stress how thankfull I am for your help, as I was very unlikely to come up with any of this stuff on my own, and even if it turns out that I need to wipe my C drive to reinstall windows from scratch at least I'll have a bunch of tools for next time (though I hope there'll be no next time).

Try

net localgroup administrators hola /add

again with "administrators" typed exactly as the first item in the list above without the asterisk *

That should work. If that works and Windows still fails to log this new administrator into the system then we can try two more things before I suggest you do a repair installation:

1) check integrity of system files:

sfc /scannow

2) re-register OLE classes

for %a in (c:\Windows\System32\*.dll) do regsvr32.exe /s "%a"

I actually edited my previous post saying that I entered the command into the console and it worked (I just had to use the spanish word for administrators), the new user is in basically the same initial situation as my administrator account, excetp the screen is not black.

I ran the sfc /scannow command and I the command line says "Windows did not find any security infraction" but at the same time I got an error message saying:

Runtime Error!

Program C:\Windows \system32\sfc.exe

R6034
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.

I think it's worth noting that the Windows folder has an extra space in it, but I'm no expert on the matter.

I guess that leaves re-registering OLE classes. I guess I'll have to make a list of my dlls and run the command for all of them, right?

No. That command makes the list and executes regsvr32 for each. Are you using 32 or 64 bit Windows?

It's 64 bit. I just didn't know how the command worked.

It's 64 bit. I just didn't know how the command worked.

In that case, you'll want to re-register your 64-bit DLLs too:

for %a in (C:\Windows\SysWOW64\*.dll) do regsvr32.exe /s "%a"

Don't worry. You'll get through this without wiping your drive and losing your files. Any idea what was installed that caused this?

I don't know exactly what could have caused it, as the las three programs I installed are Internet Explorer 9, Steam and a piece of software I use for my graduate classes called KENPAVE. At first I thought my problems booting were the result of an update in ubuntu or just me being dumb and changing a filename by mistake. But the most likely culprit is probably meclicking on the wrong link or opening a dummy file by mistake.

Hmm. Civil Engineer. Well done. How are the re-registrations going?

 

[pantabulosin]

Hmm. Civil Engineer. Well done. How are the re-registrations going?

I typed them in as they are written in here, the first time i tried it for the 64 bit ones the computer asked "more?" and I couldn't get past that. I typed them again and nothing happened in the command line. I restarted the machine and I'm basically in the same situation.

I tried adding a space in windows (think "windows_") and the output looked like /s C:"Windows" so I', about to restart again and see what happens.

cd into the C:\Windows\system32 and C:\Windows\SysWOW64 folders respectively and execute this. Looks like whatever malware you have has renamed the Windows folder.

for %a in (*.dll) do regsvr32.exe /s "%a"
