Give this ONE a try, but first uninstall the drivers you currently have.
Then reboot and try the install. Let us know if it works or not.

Does your mother board have integrated video?
If so make sure that it is disabled in the BIOS, maybe the driver doesn't like that as well.No, it still doesn't work with that driver you suggested. I am still getting the same error message. One thing I did notice however, is when I uninstalled my old driver and restarted my COMPUTER to install the new driver, I got the same error message. This tells me that it isn't the new driver at all but has something to do with the uninstall of the old driver, but what is causing this?? Thanks!!

BTW - I have aslo NOTICED this nvsvc.dll is part of my start up programs in msconfig listed under "startup." Do you think I should just prevent it from starting up by unchecking the tick box, or do you think that it is something that is NEED to start up.It's not IMPORTANT to the functionality of the video card, disable it in startup.
