Radeon 9600 XT not recognised

[jamesblond]

Hello.

Recently I've re-installed Windows XP Professional on my system, but now I've ran into a problem with my graphicscard. As soon as I install the ATi catalyst drivers, Windows finds two pieces of new hardware, but lists them as "Unknown", and is unable to find a suitable driver. These to pieces of unknown hardware have something to do with my vga board. When I look in the device manager an click on "properties" of the unknown devices, it says "on Radeon 9600 series". That is my graphics card. Also, my second monitor started shaking a little after the new windows installation. Weird...

This is what I did. After installing Windows, I first installed the drivers for my chipset, then I installed ATi Catalyst 4.7, next servicepack 1a and several other fixes. After everything is installed and seems to be running OK, the graphics card still doesn't work the way it should. It's a bit slower than normal and none of the 3D features are listed in any of the the Display Properties Pages. I
haven't tested 3D performance yet, but I have a feeling that it doesn't work, or at least a lot slower than normal.

If anyone knows how to solve this problem, It would make me a REALLY happy man!

Thanks a million!

Well, I would assume an 'Unknown device' on a graphics card is probably a monitor, and you have two because you have two monitors.

Install the drivers for your monitors and see what happens (at the very least it'll let windows know what resolutions/refresh rates the monitors support).

As for 3d Performance, I can't see why it would be affected by this, but if your monitors were running at 60hz then it wouldn't look very pretty...

Thank you for your reply.

It's not the monitors. They are both correctly recognised as "Iiyama A705 MT VisionMaster Pro 411 /i70A". I'm not sure what went wrong during installation of windows, but there used to be tabs with an ATi logo on them in the Display properties window. Thete are not there anymore. On those tabs one could control Anti Aliasing, Dualhead support, overlay settings, etc. Also, there used to be a small ATi logo in my systemtray. This could be used to switch screenresolution. It is gone as well.

If this rings any bell, please let me know.
