I was having an old system which was dying so I rebuilt the system with a new AM2+ motherboard, cpu, ram, video card. I booted off the original installation CD with Windows XP and with the original drive installed, and told the CD to repair the existing Windows installation. The updating actually went quite well and everything is working fine. But I am not able to get the ATI catalyst software to load because it says no ATI driver is installed, even after I've installed the full correct catalyst package direct from ATI's website (HD4890). When I go into Device Manager there is no longer a "display adapters" entry showing in the list of hardware, and my video card is now showing under "Unknown" at the bottom of the list of hardware. If I go into DISPLAY inside Control Panel, I do see the video card listed as a 4800 series ATI video card attached to multiple displays?
Can anyone please help. Thanks
