Hi i recently purchased an inno3d 6800 agp 8x card, i installed it into my computer and plugged everything in, pressed the power button and lo and behold the screen was black, i have tried uninstalling all my pci cards and devices, tried the graphics card by itself with no cd drives in, switched my ram around, bought a 650 watt power supply, bought a new monitor, still nothing. I also tried it on my friends sytem and it worked:/ i cant send the card back and im really stuck for ideas, anybody got a clue? by the way my setup is an ms-6590 motherboard, 768mb of pc 2700 ddr ram, amd ahtlon 2600xp+ processor, 80gb sata hard drive. also my motherboard has no onboard graphics so thats also out of the question SOMEBODY HELP ME
