I've recently replaced my 512mb ATI 4850 with an nVidia GTX 275. I uninstalled the 4850, booted into safe mode and ran Driver Sweeper. Upon reboot Windows installed my GTX for me, @#$%!!!!. In all fairness it was the latest driver but that's not the one I want.
I went in and disabled the auto update feature and went through the uninstall, Driver Sweeper routine again. Of course Windows ignored my do not install selection and did it again! GRRRRRRRRRR!
I get no dialog box explaining it is doing it so I have no way to stop it's progress. I log in and after hitting enter it takes about 10 seconds for a dialog box to pop up telling me I need to reboot to complete installation.
I went to a Windows help forum and they told me to set Windows to not install updates. Been there, done that. No worky.
Here is what I responded with, please correct me if my understanding is incorrect....
Hello Samhrutha G,
Thank you for your response. I believe your solution would work if Windows had never had the nVidia driver on the system but since it did (from when my settings were to allow updates) it installs it regardless of my settings in the Windows Update Settings area. You see I had (temporarilly) set that setting to never allow Windows to download and install updates but it ignored that (I tried with your settings too).
I think I found a solution but I may be wrong in my understanding. It is my thoughts that when you uninstall a video card driver and reboot with no 3rd party drivers on your system Windows uses it's "Standard VGA" driver. I'm not sure but I believe that is the state that we are looking for after using something like Driver Sweeper in safe mode, just the Standard VGA driver, that way a clean install of 3rd party drivers can be done.
What I've done is to use the Device Manager to navigate to my VGA card and selected the option to update my driver from a list of drivers already on my system. I was given the choice of installing nVidia's GTX 275 driver or the Standard VGA driver. I chose the Standard and rebooted. After reboot it did not try to update to the one I don't want so this is good.
My next steps will be to boot to safe mode, run Driver Sweeper to clean out any remnants of the nVidia driver, reboot letting the sytem totally load and then reboot again. I wil then install the nVidia driver of my choice.
If I am right that what users are usually trying to accomplish with the Driver Sweeper method is Windows just using it's Standard VGA driver then I am all good and my card will run better than my old less powerfull card (which is not the case now). I think I'm right because Windows would need some kind of driver to display anything on screen at all which I assume is it's "Standard VGA" driver.
Please anyone correct me if I'm wrong as I typed all that out in hopes of helping others with the same issue.
Thanks again Samhrutha I appreciate you taking the time to offer your help,
... so is my thinking right?
I'm hoping it is a driver installation issue as FSX was way, way smoother on my 4850. I've lowered a lot of settings and reduced my cloud resoltion to 1024 from 2048 and it's still not as nice as the 4850 was.
I have my fingers crossed that I can avoid the complete Windows and FSX re-install.
