Video Card not staying installed.

I'm running Windows XP Home SP1. I have an NVidia GEforce4 MX420 video card. It was preinstalled by Dell. But now, under display adapters in the Device manager all I get is "Video Controller (VGA Compatible)". I have tried to reinstall the drivers using the Nvidia drivers found at their website but still no go. I get a "Access is Denied" message with the Hardware update wizard when I try to reinstall the drivers. Does anyone know what I can do?

That's a truly odd install method. When I use Nvidia's installer, it just works. Try the easy way?

OK, so I was a little bad with my description of how I was trying to reinstall it. I tried the regular install method with the exe from Nvidia's site. And it didn't work. But for some reason, after trying it for the 4th time it decided to work. Anyway, Bob, thank's for your help.

Try windows update

In reply to: Video Card not staying installed.

Have you tried this:-
NVidia produced a winXP certified driver about November last year (its the same version as 52.16 they have on their web site) looks the same as the lastest version - you should be able to get it via winupdate - win update will auotomatically update the driver for you so it will be interesting to see if it can without any problems. If it does install OK then "go for gold" and try installing the lasest version as you may have broken the bad cycle.

I've tried that previously and and I just tried it again. Although my driver's working correctly now, the windows update driver does not work for some reason. It just says that it's unable to install.

admin privilage?

In reply to: Re: Try windows update

Have you tried logging on as the adminsitrator because it sounds as though you haven't got administrative privilage to change systems setting (for your graphics card at least)
Also are you able to view the driver details in "systems information" and/or "Help centre" see if anything shows up with "problem devices" of "conflict sharing"
Also try change the IRQ of the grahics card in your bios setup if you can - if you have recently added new hardware lately there maybe conflict.
Dell used to supply diagnostic software with their machines - have you ran these programs yet.
And one other thing, when i upgraded from an older version of the NVidia software I found that there were still some older items in in the "run" section of the registry - so run msconfig.exe and carefully check what is being loaded. What I should have done was uninstall the previous version in add/remove programs first!!!! Maybe you can try doing this first!!!???.
