Error installing Video Card: Cannot Install because driver is corrupted or missing

I have a hp pavillion 9900 and a geforce2 mx 400 video card. I was having problems updating the drivers lately until i recently encountered a new problem. I installed the latest version of the driver from the nvidia website, and when I restarted my computer the video was reset to using the standard vga adapter. Not that big of a deal. So I went to the hardware wizard to reinstall my geforce2 card when i recieved an error message saying that it could not install the card because the drivers were missing or corrupted it said it was code 39 or something. Right now im not worried about updating the drivers, I just want to have my card running, it doesnt matter which version of drivers. Please Help!!

There's more info here on above problems ;

if anyone cares to look .

nvm i fixed it, and in a strange twist of fate actually ended up succesfully installing the newest version and now all of the games work fine. I screwed up my video card to end up fixing it, and fixing my other problem. Strange, but im not complaining! ;)
