I just replaced my ASUS Nvidia GeForce 2 GTS Pro (32mb) with an ATI Radeon 9800 Pro 128 mb card and cannot get my computer to boot. The monitor goes into "power saving mode" and won't even POST. I use WIN XP Pro and and AMD 1.8Ghz CPU and an ABIT KR7A RAID mobo. My PS is a well regulated 350W and I use 2 HDD's and (1) CD-RW and (1) CD player. I disconnected (1) CD- drive but the rig still would not boot. Does anyone have any idea what the problem is here? The ATI fan on their GPU spins properly when I start up the rig and it has power from the PS. I cant find anything in the ATI troubleshoooting section about this problem. Thank you.
