I can't help a lot, as I use nVidia video cards.
But, ATI says this card needs a lot of power. Do you have two of them in a
Crossfire?
I am sure that each will require a power connection.
The release notes for Catalyst 7.2---

And---
System Requirements
a.. PCI ExpressT based PC is required with one x16 lane graphics slot
available on the motherboard.
b.. Connection to the system power supply is required:
a.. 450-Watt power supply or greater, 30 Amps on 12 volt rail
recommended (assumes fully loaded system)
c.. For CrossFireT: 550 watt power supply or greater, 38 Amps on 12 volt
rail
d.. 512MB of system memory
e.. Installation software requires CD-ROM drive
f.. DVD playback requires DVD drive and decoder software (not included)

certified components
h.. To complete the CrossFireT platform, a second PCI Express® Radeon®

Maybe you have a conflict between Catalyst and some other program, like an
antivirus program.
