So, this project has turned out to be a complete disaster. Here's what has happened so far.
1st card purchased: ATI Rage 128 Pro 32MB. Plugged the card in and when rebooting my system, it would shut down after 10 seconds. Could not install the driver as the system kept shutting down. Also, the metal front piece would not fit into the back of my box, so I had to bend the metal to make it "fit". The installation guide made reference to replacing the screw to lock the card in place. I have no such screw. Customer support tells me that this card won't work with the ATI Radeon cards because the drivers are different. Out $40 because I ruined the card by bending the metal.
2nd card purchased: ATI Radeon 7000 64MB. This time, the instrux told me to uninstall all other drivers before replacing this one. I don't want to replace the card, I want to add it to an existing card. Called ATI customer support and they told me that this card will not work with my existing card as the driver is not compatible with the "x" series. Was advised to purchase the exact same card that's already in the the box.
What is going on??? Am I being jerked around by the good folks at ATI? Should I attempt to install this second card? Someone please help as I have not been able to get my third monitor up for over 3 weeks.
Thanks in advance.
