I installed the newest version, and it wouldn't work. No values register, and when I click on any buttons, it says "The video card you selected for overclocking in ATITool does not seem to be used by Windows. Visual testing has been disabled. To fix this, go to Display Properties, settings, and enable the monitor output of the card." My specs: EVGA 7900GS GPU E6600 Gigabyte P965-DS3 (v. 3.3) Windows Vista Home Premium I scanned all over the internet and can't seem to find out how to remedy this. I went to Regedit and made sure I have administrator privileges. I uninstalled and reinstalled, and still it's not working. HELP!
