i have an ati radeon 9000 graphics cards which is running on and XP pro sp1 machine. I have instaled the latest drivers downloaded from teh ati website but the monitor keeps blinking. I know there isn't a conflict with any software because I have just formated and started from scratch. The things instaled currently are XP obviously, ati drivers and firefox. Can anybody suggest what can be done to reslove this issue?

Cheers
