I have an ASUS A8N-SLI mobo that's been sitting on my shelf or a few years. I've built several machines since buying it and had just about forgotten I had it. I bought an AMD Athlon 64 Socket 939 processor and 4 1gb sticks of DDR-400. The board doesn't have on-board video o I installed an ASUS EN8400GS 512 DDR2 PCIe 2.0 16x video card. When I powered it up for the 1st time, I got no graphics, just a beep code. 1 long beep & 2 short beeps. I looked up the codes & the only thing it indicated was an issue with the video. I was told by a tech in a local shop that a 2.0 card wouldn't work in a 1.0 slot. All of the cards I've been able to find so far are low profile 1.0 x16. Tiger Direct had one but it was sold out. Does anyone know where I can get a high profile PCIe 1.0 x16 card that will work on this board.
