How to uninstall nvidia forceware update with blank screen
Posted on 2006-06-10
Under pressure from Grandson, I installed Half-Life 2 episode 1 on a W2K machine. It did all its updates (hours) on-line but then complained that if I did not update to the latest nvidia graphics drivers it would probably fail.
I have GeForce card (don't know which right now) and was running 81.98_forceware_winxp2k_international_whql.exe with no apparent problem. Yesterday I downloaded Forceware version 84.21 and (don't laugh) installed it without doing backups. The computer cycles rebooting with an exception more or less before anything,
I then tried "safe mode" (sic) with "enable vga mode". Sure enough it now displays a login screen which will stay indefinitely. BUT any user logging in looks normal to start with, but about 5 seconds into the login, the video goes off completely. The computer is still running OK because I can access all the filestore with admin shares from a linux computer. I think that the keyboard and mouse are working also. I JUST CANNOT DO ANYTHING before the screen blacks out.
It looks like it is loading something (and I thought the culprit was nwiz.exe) during the start-up of every user. I cannot get into uninstall the update and I don't know how to do it completely blind. I tried renaming the nv*.exe files in system32 directory but it still kills the screen. I am reluctant to start re-loading W2K.
It of course COULD be something that half-life has imported, but I had rebooted with half-life on before I installed Nvidia.
I cannot telnet into the W2K machine (connection refused) and not sure that would help if I could. I tried running "NVUNINST.exe uninstall" from the "run" prompt which I did manage to type in before the black screen of death. Unfortunately it failed but that might be because I had renamed some files. I will put those back and try again.
So, the question is - can anybody help me to remove the latest "Nvidia improvement" completely blind?
