hola compi,
La verdad es que al final acabé formateando para ponerme el windows 7. La verdad es que va bastante fino.
De todas fomas te adjunto notas que encontré en foros y sitios varios que proponían algunas soluciones. A ver si tú tienes suerte:

This would be the best option, at this point. If SR is not enabled, you will need to perform the following.
This procedure enables you to edit the registry from within the Vista Recovery Environment. Be careful and follow the steps explicitly.
Follow the same steps, as in the previous message to access the RE with the Vista boot disc.
At the Repair options, select the Command Prompt option.
1. Type C: [Press ENTER]
2. At C:> type regedit [Press ENTER]
The registry editor will open.
3. In the Registry select 'HKEY_LOCAL_MACHINE' and then go to File/Load Hive.
In the 'Load Hive' dialog box, navigate to the C:\Windows\System32\Config folder.
In the Config folder, select SOFTWARE and click Open.
In the Name Hive dialog box, type a unique name, such as EDIT1 and click OK.
4. You should now see the EDIT1 branch, expand this branch and navigate to,
\Microsoft\Windows NT\CurrentVersion\Winlogon.
5. In the right side of the Winlogon Key you will see a Value called 'Shell', double click this value.
In the Value Data box, it should show 'Explorer.exe' and nothing else. If it shows something different, change the Value Data to Explorer.exe.
Click OK.
6. Scroll back up and select the EDIT1 branch.
7. Go to File and select Unload Hive.
Exit the registry editor and the command prompt. Press the 'Restart' button to reboot.
Reboot normally.
Let us know the result.

http://support.microsoft.com/kb/946532FIX: Event Log Corrupt
Thread has many different approaches to solving the same symptoms. So, maybe this post will help others.
My black screen after logon: system hung with no response to control-alt-delete. Only thing that worked was pressing SHIFT KEY 5 TIMES. The sticky key assistant opens, then you can CLICK the link to edit advaced settings. This got me to an explorer, then manually entered into the address line
c:\windows\system32\msconfig. Using that tool, you can go into diagnostics mode and shut down services and startup tasks. Restart the computer.
Using msconfig I narrowed down the cause of the black screen to the Event Log Service.
Using that knowledge, was able to find the log files (new to vista: they're stored in a dedicated folder vs. the old .evt files of previous Windows versions.)
