Hello.........I have a Gainward Ti4200 G-4 card and I'm trying to update the driver. First....I have no anti-virus software, or anything else running. I deleted my old driver (4230)from add/remove programs. I downloaded a newer driver from the Nvidia website, because Gainward ended their driver updates for this card at version 4230. It unpacked the files to the default folder. I then went to my display adapter in 'System Properties' and selected 'update driver'. I point it to the folder where the newer driver,etc. is, but it won't install.........the update wizard says that an appropriate driver cannot be found. Any ideas to try??? At the moment, it looks like the generic Microsoft driver is installed (version 2980). Thanks....
