Couldve answered the question while you were moving the post. Im afraid to hit "NEXT" on my Ati Software installation wizard waiting for that all elusive answer.
You aren't providing much info to go on.
You say its a new card so we assume you are installing with
the ATI cd.
What's the worry over the "NEXT" button?
If a new system, have you installed the motherboard/chipset drivers?
If not a new system, did you completely uninstall the old video drivers?
If it was an nVidia card, I often see experienced users advising the use of DriverCleaner
to clean them out completely: http://www.drivercleaner.net/dc.htm
Your ATI cards manual should guide you through the install.
Most people use the "Custom" install and choose what they want installed.
When you get the card installed, the drivers will be old.
1. Start >Control Panel >Add or Remove Programs >ATI Catalyst Control Center >Remove.
2. Do not Restart when prompted.
3. ATI Display Driver >Remove.
4. Restart when prompted.
5. Upon return to Desktop in Windows Standard display, cancel offer to install drivers.
6. Start >Run >browse to where you downloaded the new ATI Catalyst driver package and run it.
If the above doesnt work out, download this util: ATI Catalyst uninstaller https://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&folderID=27 Utilities >Various >CATALYST ATI Maintenace Utilities > cat-uninstaller.exe
This will clean your system of any ATI software along with any remnants that could be causing problems.
Use it instead of steps 1, 2 and 3 above; then continue with steps 4, 5 and 6.
