radeon x550 blackout after installing

Specs: Windows XP
after my reformat i installed my latest chipset, soundcard, network drivers. When I try to install my the latest videocard drivers, setup runs fine through everything. I get the message that on the next restart my drvers will be tested for the first time. So i reboot and after the Windows XP loading screen i get a blackscreen with very few scattered dots and my computer freezes. I gotta restartand boot with last known config to get back to where i started.
Under other devices, in device manager, it lists.

#1 -Video Controller
#2 -Video Controller(VGA Compatible)

I've tried updating the driver manually and finding the driver set to where the .exe extracted it too.

For #1 manual install, installation goes fine and drivers install, it then list itself in device manager as Radeon X550 PRO Secondary, then ask me to restart.
For #2 The drivers start to install and at the end, it stops itself and says "Unable to install, Access Denied" .

Please help what can I do with this video card, is it broke?

Which driver did you try? You should be installing the ATI Catalyst driver version 9.3.1 & if you intend to use the Catalyst Control Center, you need to install Microsoft .NET Framework 1st.
