Default Switching from Nvidia to Ati.

Allright I've always been with Nvidia, and now i've decided to upgrade my 8600gt to a 4870. Finally!

Now, i just want to make sure i do everything correctly for switching.

1-Uninstall drivers with driver cleaner
2-Go to safe mode and clean what's left with driver sweeper
3-Switch card, install catalyst and be happy.

Is this fine? I read in some other forums that driver cleaner could bring more trouble and i should just uninstall the drivers from my control panel. I also read in other places that going into safe mode and using driver sweeper is useless.

What do you guys think about that? Any other things i should know or be warned? I already dowloaded catalyst 9.3 from ati's site.

I got Xp Pro 32 bit, e8500 and p5q pro.

I suggest an complete OS re-install, however, be sure to update DirectX BEFORE installing the drivers for your new card. If you have Phys-X installed, remove it and install 07-13 package from Ageia, not one from nV.

nVidia drivers are known to change required Windows files in such a way that it hampers ATI card performance, in just your situation. This isn't some conspiracy or anything, it's just what nV drivers do in order for the VGA to work properly. ATI renders differently from nV, so those files being changed have an minor effect.

I've never heard of this and always use DriverCleaner!

Have never heard of this either and always Bot into Safe Mode and run DriverCleaner more than once until no more Video Drivers appear to Clean.

Driver cleaner doesn't do anything that you wouldn't have to do manually anyway.

Removing uninstalled hidden devices will have the same effect, and DOESN"T require safe mode. It just requires you have a different part installed...and if you do not, there's really no point to it, IMHO, unless you are using beta or modded drivers.

Same here, never heard ANY of this.

Personally, while a driver scrubbing will most likely work, your best best would be to do a fresh OS install.Go ahead and try scrubbing the drivers first, but be fully mentally prepared for a full OS reinstall if you encounter any strange(performance, stability, etc) issues.

Here is what i do and you can imagine how many times I have done this....

Go into Device Manager
Uninstall Nvidia card and the Nvidia uninstaller will pop up
Restart and boot into Safe Mode
Use Driver Cleaner (the REAL one from Drivercleaner.net)
Use Driver Sweeper
Shut Down
Install new card

since I dont feel like starting a new thread for essentially the same question, is the procedure any different from ATI to ATI?

Nope.

But if just updating the driver, simply use the ATI catalyst uninstaller, reboot if required, then install the new package.

SKY's method is probably the best, however, the card will still show in device manager until you remove it(although it will be hidden).

You mean upgrading the drivers or switching out the card?

Either way, here is my ATI procedure.

First of all, DO NOT go through the Device Manager.

Open the driver file of the CURRENT ATI DRIVER you have installed.
Go through the prompts until it asks you to either Install or Uninstall
Click Uninstall
Reboot into Safe Mode
Use Drivercleaner.net and Driver Sweeper
Uninstall the card

I do not use device manager to uninstal teh card, SKY; after uninstall i remove the registry keys for the old hardware by using device manager, rather than by driver cleaner/driver sweeper.

This is where we differ...you use a tool to do it, I do it manually. Yours is probably better for odd file removal. Just note that additional devices installed for audio won't be fully removed, neither will drivers for monitors conected via the old card.
