I've found a fair few posts on this card, think mine's a slightly original problem though so I'll post a new thread! Bit of background first. Unlike most of you here, I guess, I'm not into games in the slightest on my PC. I use it as a digital audio workstation and the most important considerations to me are stability, multiple monitors and not pinching any of my system RAM. For the past two years or so I've had a PC with the following spec: P4 3.2HT 2GB RAM Abit IC7 mobo Radeon 9250 128MB AGP M-Audio Delta 1010LT Intel Pro 100/S NIC I've been running two screens off it, no problem, in fact this is about the best machine I've ever built, performing flawlessly with everything I've thrown at it. Recently went to add another two screens (hey, I was given them, and screen real estate is VERY important for audio ) and thought 'well, that Radeon 9250 has done me proud, no worries etc, I'll just get the PCI version of the same card'. So I did. Dual output Radeon 9250, 128MB Ram, except on PCI. Turns out to be something of an error.... the machine either fails to display anything on the 2 original screens or hangs halfway through POST (after CPU detection, before RAM), depending on which PCI slot it's installed in. 3rd & 4th screens both display 'no input signal' at all times. Obviously my situation is different to most other posters on this card, as I still want to use the original AGP card when the PCI one is installed! Any ideas what's causing this? Can't be Windows drivers as it doesn't even boot that far, I'm thinking its defaulting to the same IRQ as the other one or something? Help would be appreciated.
