I recently purchased a Chaintech Geforce FX5500 256MB DDR AGP 4X/8X video card from newegg.com. Additional stats: Core clock: 270MHz D-SUB: 1 DirectX: DirectX 9 DVI: 1 Max Resolution: 2048x1536@85Hz Memory Clock: 400MHz OpenGL: OpenGL 1.4 TV Tuner: No TV-Out: S-Video Out VIVO: No I've been using an old Geforce 2 32MB card (don't have the specifics at the moment) and it was working fine, albeit sub-par for new games (namely Guild Wars). I'm using an ASUS A7V133 Socket A motherboard, 200/266MHz FSB AGP Pro/4X (if you need any other info or specs let me know and I'll provide what I can). Long story short: I correctly and safely removed the old card, input the new card, and nothing happens. My monitor says "no input/check cables". Obviously, something is going on with this card. I'm not sure if the problem is with the card itself, or its compatibility with my motherboard. I'm not a genius when it comes to pc hardware (that's why I'm here) and basically I have two questions: 1. If this video card can work with my motherboard, what do I need to do to get it to work? 2. If this video card cannot work with my motherboard, what's the best video card I could buy that would be compatible with what I've got? Also, considering the motherboard I DO have, if I indeed I need to replace this card again, what should I look for so I don't order the wrong thing? Any assistance will be GREATLY appreciated. Thanks.
