Sounds like a faulty userinit.exe file, or registry entry to it

Try this:

1.- Get into the recovery console (with boot disks, you can get them from microsoft page, even use the Ultimate Boot CD)

2.- Get the file userinit.exe from another NOT INFECTED computer. (located in windows/system32 folder)

3.- Overwrite the userinit.exe original file (from the infected computer) with the new one (use a cd or disk to transport it) (COMMAND: COPY e:/userinit.exe c:/windows/system32/userinit.exe)

Note at this stage it may work
If not try the following:

4.- Rename the userinit.exe to wsaupdater.exe

5.- Exit
