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
