I bought a new graphic card and I need to uninstall the ATI Catalyst and it will not uninstall. I click on the express uninstall and it goes to the generate list in custom uninstall and never loads the list. Runs for hours and does nothing. I bought a new Nvidia card and have to get this uninstalled so I can install the new card. Should I try the uninstaller program in system mechanic? They used to have programs to uninstall ATI and I could not find one, Any Ideas? Thanks
That command prompt install/un-install procedure should be sufficient to do the job. On my second quad core machine, i just install nvidia driver after the command-prompt un-install of ATI software. I took out a 4890 on that machine and installed a GTX280.
The drive sweeper should also work.
The procedures outlined on this thread should work. I tried these options myself. I have 2 quad core machines. One nvidia (GTX280) and other other is ATI (CF 4890).
In the last 8 months i played around with video cards on these 2 machines i use different methods of un-installing drivers. They all work...
- Drive Sweeper
- Command Prompt Un-install/Install
- Regular Install/Un-install for both Nvidia and ATI.
The last thing that i want to do is fresh windows installation because it requires a lot of work. That's the last resort that i use. I have never made a fresh install in more than 1.5 year on the 2 machines that i have. But there comes a time that the registers are already messed up that a fresh install is required.
As suggested in this thread fresh install is always a valid option(Clean Start).
Yes, I agree a full reinstall is not fun, especially if it doesn't help.
What I'd actually suggest is buying (or finding) an old, empty hard drive. That way if you are ever having problems, you can do a fresh install of windows (without wiping your current) to see if that resolves anything. Even that though is time consuming and a last resort.
2) Download your new driver to the same place.
3) Add/remove programs, uninstall any Nvidia or ATI vga drivers and programs.
4) Boot into safe mode. Press F8 repeatedly while booting to enter safe mode. Your display resolution may be minimal.
5) Run driversweeper. Check the selection boxes for the removal of all nvidia vga drivers and ati drivers.
6) Rerun driversweeper. All such components should be gone.
7) Install the new driver from the desktop or saved location.
