Ok, Let me explain what I've done.
I use to have a ax5450 1gbk3-sh Card in my computer(1gig PCI-E x16 2.0). I've bought a 830W power supply and a Radeon HD 6970 2.0 2G DDR5 Graphics Card. When I removed the out card and added the new card with the new power supply, I get a long beep with 2 beeps after. As I looked into it. I found out its a graphic card error or display. I put the old graphic card back in with the new power supply and it boots just fine. I put the new one back in and same problem. Both cards are PCI-E 2.0!!! Difference between these 2 cards are that one is a 2 gig and that it takes power from the power supply(2 connectors). Anyone have any idea why this card won't display? I'm using HDMI on a TV. Thanks for reading.
