NVidia Driver Failure From Windows 7 Update?

This occured just hours after I first registered for this website.I have had some problems with updating the drivers for my EVGA GTX 460 SE 1GB and it has been giving me h3ll about it.Innocently, just hours after I registered for this site, I was going to do a Windows update as I hadn't yet done one in weeks and decided to do the optional update on Windows 7 Pro for a new nVidia driver as I do with everything.When I downloaded it, installed, then restarted, my computer started to act kind of funny. For the most part it was pristine, but it started and continues to operate funny with the visual display.1) During the second Windows loading screen, the one after the glowing Windows logo, the screen quickly flickers to black and back to the screen during the process. It does this sometimes while I'm navigating in Windows as well using some programs albeit somewhat infrequently.2) The driver update screwed up my desktop display immensely as it is now. When I originally installed the nVidia driver from the EVGA cards software CD, I noticed the picture quality and resolution jumped up immensely and added higher resolutions to my desktop settings. Icons got immensely smaller, more windows with smaller text could fit on the screen, the cursor was half the size about, and my start menu and bar with it's icons, shrunk down a bit smaller too. That was the healthy behavior. Now when I did this Windows Update for the nVidia display driver it messed everything up to what it is now. Everything is blown up in size. And when I tried to uninstall all the nVidia software, restarting, and then installing it again using the latest driver download off of nVidia's website, the same stuff. I can see the uninstallation of the driver causes it to revert to I take it some default Windows visual driver lowering the max desktop resolutions and that reinstalling the driver off of the website does indeed add the higher resolutions and the visual appearance does change where the cursor, icons, etc. aren't as pixelated, but everything is still oversized instead of shrunken down like as is normal. It says my desktop is at 1680x1050 as the monitor is and what stuff on my desktop has on it looks more high-definition, but the actual size of icons, cursor, etc. almost suggest like it's running on a lower resolution.3) As I tried to reinstall the driver from the website and it didn't do much to change the problem, I tried instead to use the CD again and it's giving me h3ll about it. I even went so far as to uninstall it through both normal and safe mode boots and do a Norton Utilities scan to scan for junk files and registry entries as well as try some driver cleaner software to get rid of excess stuff that may not have been gotten rid of, and then use the EVGA driver CD. But the driver CD will show up the autorun window, but then when I try to install the drivers it gives me an error message saying "Access denied". Why is it doing that?And I know fully well it's the Windows Update of the nVidia driver that is doing this because it did it just after I installed it. It screwed things up BAD and will not do something so stupid as taking their nVidia updates from this point on, but the question still remains... How do I get the d@mn drivers to work PROPERLY? How do I get the visual display to be 100% FULLY WORKING?
