Vista Logon.scr error

When I boot up my PC with Vista on it, it goes into a black screen for 10-15 minutes followed by an error regarding logon.scr All I see is my cursor and a black screen. I was previously deleting nvlddmkm.sys files on my computer and then I restarted and it's been like this since. Is there a way to get into my computer now? All I'm seeing is black and an error after staring at the screen... Can I enter the boot menu and somehow get in? All I was doing was trying to get rid of a display driver error and now I can't even access anything on my computer :x

Since I can't screenshot the error I'll just type it out.

Application Error
The application failed to initialize properly (0xc0000022) Click ok to terminate the application.

That's all I can see on my black screen with cursor..

Try performing a System Restore, either from Safe Mode or from the System Recovery dialog...

Using Windows Vista System Restore

that'll erase everything I had on my computer right? I've tried to repair but it's not working so I guess this is my only resort. I was hoping to save my files :/

System restore only affects system files, the data on your machine will not be affected.
