hi guys. I bought a new video card today, the ati radeon hd 5570. I installed it and downloaded the latest video card drivers from ati's site. When i install them, the installation gets to the point where it says detecting graphics hardware but the check never finishes. It goes on and never stops and i have to restart the computer to get rid of the catalyst process to try again. I have tried using driver sweeper in safe mode and normal mode and the installation still freezes. I go to my hard rive and search ati in the search bar and i get many dll's and other files that start with "ati". I dont want to delete all of them incase something might happen. These files were not removed by driver sweeper. I erased all ati folders using regedit. nothing seems to work. I have windows vista home premium 32 bit. I have uninstalled the device from device manager and removed all the installation folders on my hardrive to no avail. Any advice would be appreciated. Thanks in advance.
