My media centre XP 2005 needed reinstalling. After quite a palaver I have it managed to install the OS. Now when I install the ATi drivers for the graphics cards I get the start up Ok but after clicking on a Windows users name the screen goes blank a few moment later and that is the end of it. Problem is present on large TV monitor and small PC monitor when plugged into graphics card. I can start in safe mode on the PC monitor only, go to device manager and uninstall the drivers. Then I can get going again but when I install the drivers I am back in the loop. Any suggestions please? It is an ATi Radion 350/550/1050 accoring to the info in the device manager. The driver is the latest from the ATi site (8.1).
