Windows 7: Black screen before login HELP! -thorough information

10 Jul 2011   #1

Windows 7 Home Premium 64bit
Black screen before login HELP! -thorough information

Whenever my computer starts up, right after the windows logo goes away and right before I can even get to the login screen, my screen will stay black forever and all I can see is my cursor and if I wait there for a few seconds an error pops up, it reads runtime error C:\windows\system32\nvvsvc.exe

nvvsvc.exe is apparently part of my nvidia drivers (I have a gtx 260 core 216) it could either be that my drivers are corrupted or a virus used the same name. I replaced nvvsvc.exe and the problem persists, I also re installed my video card drivers and its not fixed.
Heres a few more things ive tried but still with no luck. Safe mode does not work it will do the same thing, give me a black screen and the runtime error.
I've also tried system restore, didnt work.
I've installed ubuntu and im backing up everything important on that hard drive in case i have to system restore.

Im trying to pinpoint the problem here since it wasnt nvidia drivers. The last thing i did when my computer was working was I changed some startup items and I also deleted something I think I believe I shouldnt have.

I noticed widgi toolbar was running and with a quick google search I learned that it wasnt good to have so I looked up the registry for it and deleted it. After all my changes, I restarted my computer and its been hung up ever since.
