Hello,

After removing an old, & inserting a new graphics card & associated software/drivers, my PC won't get past the loading Windows stage.

It does startup without the ATI drivers (presumably using Windows drivers), but not when the ATI ones are installed.

I had removed the old drivers. I have re-tried using latest drivers from ATI.

6Pin Power supply connected.

System;
Pentium D 2.8Ghz
Ram: 2048mb, DDR2 667Mhz
'Old' graphics: ATI Radeon X1550 (single card tho 'primary' & 'secondary' noted in system info)
New card: ATI Radeon HD 4850, (Sapphire, dual slot version).
OS: XP Media Center 2005, SP2,
Mobo: Asus P5SD2-FM
PSU: 600w OCZ GameXtreme.

Appreciate any ideas to resolve this,

Thanks,
timtechless.

BTW: Its a Scaleo P 6405
